Executive Summary

The objective of this senior design statement is to consider the conversion of N 3rd Street

and N 4th Street from one-way streets to two-way streets in Grand Forks, North Dakota. The

proposed alternatives designed for this project convert N 3rd Street and N 4th Street to two-way

streets, reconstruct the north side of Gateway Drive and N 3rd Street and 4th Street, or change

nothing. The goals for this project focus on safety, efficiency, and sustainability. This significant

urban planning initiative, encompassing the area between Gateway Drive and University

Avenue, is poised to bring about a myriad of benefits, with a particular emphasis on these

specific goals.

The conversion to two-way streets is anticipated to significantly enhance safety by

simplifying the traffic flow and minimizing complex intersection dynamics in these areas. This

aims to create a secure transportation environment for all vehicles and pedestrians in the area.

Not only do these alternatives enhance safety, but the proposed alternatives also focus on

efficiency by using a redesigned street layout. It is proposed when designing alternatives for

these streets to optimize traffic flow, reduce congestion, and offer a more streamlined

transportation experience throughout the city. This has a far-reaching implication for

convenience, productivity, and overall higher quality of life. The last of the more prioritized

goals in consideration is the sustainability factor of this conversion. With an emphasis on the

possible impact of converting from one-way streets to two-way streets, the alternatives minimize

disruption of the environment and surroundings to maximize sustainability efforts.

Other factors considered in the process of designing alternatives for the idea of

transforming N 3rd Street and N 4th Street’s one-ways are the optimization of traffic signals,

working within traffics codes, cost, and possible limitations and constraints.

The existing traffic signals and their proximity to the proposed changes are analyzed to

ensure that the signal design aligns with the City of Grand Forks traffic control standards and

guidelines. The project’s designs follow the North Dakota Department of Transportation

(NDDOT) Traffic Operations Manual in considering the need for left turn lanes, right turn lanes,

and traffic signals at intersections.

Another factor that is being investigated is the estimated costs for the three design

alternatives. The conclusion derived from the data suggests that the first alternative of changing

N 3rd Street and N 4th Street from one-way to two-way would be costly. The limitations

considered in these alternatives include restricted space surrounding the one-way streets in this

project’s scope. The impact on the existing businesses and other surrounding existing structures

are considered in preserving the right-of-way and possible implications for pedestrians and

school access.

Design Recommendation

Thorough investigations were formed into multiple alternatives for the proposed two-way

street conversion project. It determined that a complete overhaul of the roadway geometry,

layout, and flow of traffic surrounding Wilder Elementary is necessary to provide the greatest

positive influence upon the school and surrounding area. This work will remove of a current

traffic light system along Gateway Dr, and 11th Avenue N and replace it with a new traffic light

at Gateway Dr, and N 4th Street. A raised median will be installed along Gateway Drive that

extends from N 3rd Street to N 4th Street. 11th Avenue N will be converted into a hammer-head

turnaround. A right turn lane for N 3rd Street will be added along Gateway Drive.

These changes will help improve, and align with the city’s goals for transportation

quality, as well as those who it directly affects. The proposed changes do not only impact

mobility, but also the overall urban experience for residents and visitors, positioning Grand

Forks as a city that embraces modern urban planning principles to prioritize the overall health of

the transportation networks of their community.

1.0 Introduction

The city of Grand Forks, North Dakota is working towards a more urbanized

development, motivated to redefine its transportation infrastructure to meet the growing demands

of a dynamic urban landscape. Part of this transformation are the proposed alternatives aimed at

the conversion of N 3rd Street and N 4th Street from their existing one-way configuration to a

two-way, spanning the stretch between Gateway Drive and University Avenue. This ambitions

initiative holds the potential to improve traffic flow and enhance accessibility within the city,

with a commitment to safety, sustainability, and efficiency driving the project forward.

The two proposed alternative designs consider minimal change to the road’s geometry

and layout against a full overhaul design of the layout and geometry surrounding Wilder

Elementary. As the demographics of Grand Forks shift and urbanization accelerates, the

initiative to optimize transportation networks becomes increasingly pronounced. The design

alternatives for the conversion project embody a proactive approach to meeting the evolving

needs of a growing city, rooted in a comprehensive understanding of the area’s traffic dynamics

and urban design. The conversion from a one-way to a two-way of N 3rd Street and N 4th Street

is discussed with a proposed idea of implementation while prioritizing the transportation

infrastructure to align with the growing city’s needs and aspirations.

1.1 Challenges During Design

Wilder Elementary School is located between N 3rd Street and N 4th Street and immediately

adjacent to Gateway Drive.

A chain link fence separates N 3rd Street from Wilder Elementary School. Additional

signs are also implemented to improve safety around the school. The pedestrian tunnel

under Gateway Drive remains intact and sees improvements and upgrades.

N 3rd Street currently has a left turn lane and a right turn lane and could not support a

southbound lane as is.

In both design alternatives, N 3rd Street only accommodates right turns from N 3rd Street

onto Gateway Drive and right turns from Gateway Drive to N 3rd Street. This provides a

safer environment and restricts Gateway Drive traffic from making a left turn onto N 3rd

Street without a traffic light.

There is an existing traffic signal at Gateway Drive and N 3rd Street and 11th Avenue N so

adding additional signals at N 3rd Street or N 4th Street would be too close to the existing

traffic signal.

Alternative one features minimal changes to the current setup and only requires new

striping of pavement markings. The traffic signal stays in its current location. In

alternative two, the traffic signal at 11th Avenue N is removed and a new traffic signal is

placed at the intersection of Gateway Drive and N 4th Street.

Currently, N 4th Street only allows parking on the west side of the road, however vehicles

dropping off and picking up school children from Wilder Frequently Park on the east side.

So, the new layout should address this concern.

In both design alternatives, a drop off and pick up section is exclusively designed for

Wilder Elementary. N 4th Street is widened between 11th Avenue N and 10th Avenue N

for the addition of this lane.

Could N 3rd Street and/or N 4th Street be realigned to better connect to the streets north of

Gateway Drive?

Alternative two realigns N 4th Street with Gateway Drive. This improves the street’s

safety and efficiency.

Could N 3rd Street be changed to a cul-de-sac and not connect to Gateway Drive?

The design team reviewed this concept but decided against it. There is enough room to

construct a cul-de-sac, but keeping both streets connected to Gateway Drive provides

better traffic flow and prevents all traffic being forced onto N 4th Street. Cul de sac is a

very possible option, but the design team prefers to keep connection of 3rd St to Gateway

Dr.

Is it feasible to purchase/relocate business if additional property is required?

Alternative two require right-of-way purchase for the hammerhead on 11th Avenue N.

The additional turn lane will also require right-of-way if one is installed.

If N 3rd Street and/or N 4th Street are realigned how does this impact the existing shared

use path?

Both alternatives do not impact the shared use path. The shared path remains in its

current location.

Project Limits:

N 3rd St & N 4th St between Gateway Drive and University Avenue in Grand Forks,

North Dakota.

Figure 1 Project Limits

2.0 Existing Conditions

2.1 Land Use

Most of the land adjacent to N 3rd Street and N 4th Street is single family residential. At each end

of the project area for N 3rd Street and N 4th Street, the land use is commercial. The land

surrounding the project area on Gateway Drive is used for commercial purposes. The impacts of

these residents and businesses will be specified.

2.2 Existing Roadways

Figures 2, 3, and 4 show the existing typical sections for N 3rd Street, N 4th Street, and Gateway

Drive.

Figure 2 N 3rd Street Existing Typical Section

Figure 3 N 4th Street Existing Typical Section

Figure 4 Gateway Drive Existing Typical Section

2.3 Right of Way

The Right of Way (ROW) for N 3rd Street varies from 44 feet wide to 73 feet wide. The

roadway width varies from 28 feet to 43 feet. The berm on each side of the roadway varies from

1 foot to 15 feet. There is a 6-foot-wide sidewalk on each side of the roadway. The ROW for N

4th Street is 66 feet wide. The roadway width is 36 feet wide. There are berm widths of 15 feet on

each side of the roadway. There is a 6-foot-wide sidewalk on each side of the roadway. The

ROW width for Gateway Drive varies from 79 feet to 99 feet. There is a 4.5-foot-wide sidewalk

that is flush to the curb on each side of the roadway. There are varying widths of berm on each

side of the roadway.

2.4 Utilities

There are underground utilities within the area of the project. There are electrical,

telephone, and fiber optic cables beneath the ground. There are also stormwater and sanitary

lines underground. These underground utilities will need to be identified to ensure they are not

damaged during construction.

2.5 Traffic

2.5.1 Average Daily Traffic

Figure 5 shows the average daily traffic (ADT) for N 3rd Street, N 4th Street, Gateway

Drive, and the surrounding streets. These values are obtained from the Grand Forks GIS and

from the year 2022. N 3rd Street has an ADT of 1,005. N 4th Street has an ADT of 400. Gateway

Drive has an ADT of 16,380.

3.0 Project Design

Two different design alternatives were analyzed. One design provided minimal change to

the road geometry and layout. The other design contained a full overhaul of the layout and

geometry surrounding Wilder Elementary School. Table 1 below highlights the total cost and

The complete overhaul alternative was proceeded with because it provided the best traffic flow

and safety around Wilder Elementary School.

Table 1 Design Alternative Comparisons

Design Total Cost Construction Feasibility

Minimal Change $351,291.00 •Simplest

•37 Construction Days

•No Road Closure

Complete Overhaul $864,045.00 •Hardest

•109 Construction Days

•Road Closure and Lane Reduction

3.1 Complete Overhaul

The second alternative proposes major changes to the N 3rd Street, N 4th Street, and

Gateway Drive intersections. A complete overhaul redesign is made to the roadway layouts and

geometries. At the intersection of N 4th Street and Gateway Drive, a new traffic light system will

be employed. A raised median will run from the intersection of N 4th Street and Gateway Drive

to the intersection of Gateway Drive and N 2nd Street. This alternative brings greater construction

costs and more time for this project to be designed, approved, and constructed. A major concern

facing this alternative is preventing unauthorized left turns onto Gateway Drive from the streets

south of the intersection.

Figure 12 Alternative 2 N 4th Street Typical Section 0+50 to 3+50, 7+00 to 37+00

Figure 8 displays the new layout for the proposed signalized intersection at Gateway

Drive and N 4th Street. A right turn lane is constructed on N 4th Street to head east onto Gateway

Drive. Property acquisition is obtained from Fox Radiators. The current inlet is turned into a type

C R-1733 manhole. Figure 9 shows the intersection of 11th Avenue N and Gateway Drive. In the

proposed layouts for the second alternative, on the north side of Gateway Drive and the N 3rd

Street/11th Avenue N intersection, the traffic signal is removed and the north leg of N 3rd Street is

converted into a right-in-right-out street. N 4th Street is turned into a signalized intersection.

Figure 10 portrays the proposed intersection for Gateway Drive and N 3rd Street. The

raised median extends through N 3rd Street and converts the intersection into right-in-right-out

only. A right lane is implemented heading east on Gateway Drive, which turns onto N 3rd Street.

This prevents backup of the through lane and allows for a comfortable right turn. The

intersection of Gateway Drive and N 3rd Street/11th Avenue N is converted to a right-in-right-out

intersection and the raised median prevents left turns. A crosswalk is designed at the intersection

of N 4th Street and Gateway Drive to redirect crossing and allow safe travel. It also gives a

crossing route for when the pedestrian underpass is flooded. N 4th Street on the south side is

widened to create room for turn lanes. On the north side of Gateway Drive, N 4th Street has a left

turn lane and a right/thru lane. The south side of Gateway Drive and N 3rd Street is turned into a

right-in-right-out street. A right lane is added to reduce the impact of eastbound traffic on

Gateway Drive. The median extends from N 4th Street to N 2nd Street to prevent unauthorized left

turns. 11th Avenue N is closed off and turned into a hammerhead turnaround. The catch basins

shown above are readjusted to the geometry of the hammer-ended section. Property acquisition is

acquired from Fox Radiators to create room for this change. This allows for extra pickup and

drop-off space and allows for easy access out of 11th Avenue N, as well as snow removal during

the winter months.

Figure 14 Alternative 2 N 4th Street Typical Section 3+50 to 7+00

Figure 1 shows a proposed pick-up/drop-off zone along the north side of N 4th Street,

adjacent to the school. No-parking signs are added for regular school hours to prevent clogging

of the lane during school hours. This allows for extra pick-up spots for parents and buses to pick

up children on the same side of the school, which reduces the chance of accidents occurring.

The plan of action regarding traffic control and how to move vehicles, and pedestrians through

the construction of the proposed layout will be implemented in 3 phases. Highlighted below, are

those 3 phases highlighted in greater detail. It is important to note that N 3rd Street, and N 4th

Street will not be open to two-way traffic until full completion of construction, as it is not

feasible, and not safe to open until construction along Gateway drive is completed.

Phase 1

The area concerning Phase 1 is the intersection of 11th Avenue N and Gateway Drive. This part

of the process will include the removal of the current traffic signals; constructing the right turn

lane going into N 3rd Street, and construction of the hammer ended intersection as well as the

storm sewer adjustment.

Figure 15 Phase 1: Traffic Control Work Zones

Shown in Figure 1 is the proposed layout of the traffic control devices utilized during the

first phase. Shown in yellow represents work areas and road closures. Channeling devices

utilized will be tubular markers for daytime and speeds not exceeding 40 miles per hour. Road

closure barricades will be type III barricades with road closure signs attached, per NDDOT

standards. N 3rd Street is converted into a temporary right-out lane to prevent any confusion for

drivers planning to turn left onto Gateway Drive. 11th Avenue N, on both sides of Gateway

Drive, is closed to allow room to remove the current traffic signals, as well as the construction of

the hammer ended turnaround and the adjustments made to the storm sewer. Gateway Drive is

reduced to the outside lane in each direction to allow for construction of the raised median.

Phase 2

Phase 2 occurs at the intersection of N 4th Street and Gateway Drive. The scope of work

nucleus in this phase includes the installation of the new traffic signal, as well as the

implementation of signal timing and crosswalk adjustment. N 4th Street is widened to allow for

the added right turn lane. The conflicting storm sewer is readjusted. Gateway Drive is reduced to

the inside lane both ways to allow for construction room. Figure 14 below shows the lane

closures and work zones to complete these actions. Figure 15 below, highlighted in purple

arrows, shows a detour route to manage the partial N 4th Street closure.

Figure 16 Phase 2: Traffic Control Work Zones

Figure 17 Phase 2: Traffic Control Detour Map

Phase 3

The last phase opens N 3rd Street and N 4th Street as new two-way pairs. This will include

repaving N 3rd Street and N 4th Street, beginning with N 4th Street. Road closure extends all the

way from 11th Avenue N to University Avenue and a detour plan enacts. It is highlighted in

purple arrows in Figure 1. 10th Avenue N remains accessible to allow for bus pick up and drop

off. Like N 4th Street, N 3rd Street closes from Gateway Drive, extending to University Avenue.

N 4th Street will open to two-way traffic and all N 3rd Street traffic is routed to N 4th Street.

Signage is removed and readjusted along the street length extending from Gateway Drive to

University Avenue, turning the intersections of N 3rd Street, N 4th Street, and University Avenue

into four-way stops. To adjust for new traffic flows, pickup and drop off zones along N 4th Street

are created along the side of the school. Pavement markings are added along the whole project

area.

Figure 18 Phase 3: N 4th Street Detour Map

6.0 Cost Estimates

Table 2 shows the cost estimate. The estimate includes paving the entirety of N 3rd St and

N 4th St with asphalt and milling between 00+50 and 11+50 on N 3rd St. Asphalt is also used to

construct the hammerhead on 11th Avenue N. The most expensive bid items are the Gateway

Drive and N 4th Street traffic signal system, the curb, gutter, and median concrete, and the

asphalt paving. Traffic control signs are estimated using “Traffic Control Requirements for

NDDOT Operations on Highways and Streets” for lane closures on a multi-lane road with

reduced speed. The standard drawing for the traffic control is shown in Figure 17. Table 3 shows

the number of traffic control signs needed for each phase. Table 4 shows the 2023 NDDOT

specifications for temporary traffic control. The specifications are listed in appendix A.

7.0 Conclusion and Recommendations

7.1 Conclusion

The transformation of N 3rd Street and N 4th Street from one-way to two-way roads in

Terrific Forks, North Dakota, presents a huge metropolitan arranging drive pointed toward

improving security, effectiveness, and maintainability inside the task region. The existing traffic

signals and their proximity to the proposed changes are analyzed to ensure that the signal design

aligns with the city’s traffic control standards and guidelines. Through an exhaustive examination

of the current circumstances, including land use, street setups, option to proceed, utilities, and

traffic designs, as well as thought of different plan choices, the venture group has recognized key

difficulties and potential open doors for development. Elective One spotlights insignificant

changes to the current format, principally changing over N 3rd Street and N 4th Street into two-

way roads while consolidating raised medians and assigned go paths to advance traffic stream

and improve security. Elective Two, then again, proposes major overhauls and crossing point

realignments to address traffic concerns more thoroughly, including the establishment of new

traffic lights and the production of turn paths and pickup/drop-off zones close to More stunning

Primary School. The impact on the existing businesses and other surrounding existing structures

are considered in preserving the right-of-way and possible implications for pedestrians and

school access. All through the plan cycle, a few difficulties were distinguished and tended to,

including obliging existing foundation, guaranteeing person on foot security, limiting

interruptions to organizations and inhabitants, and complying to traffic light principles and rules.

Nitty gritty development plans and traffic signal measures have been illustrated to work with the

smooth execution of the proposed changes while alleviating possible interruptions to traffic and

encompassing exercises.

7.2 Recommendation

Considering the exhaustive examination and assessment of the other options, as well as

considering the project’s goals and the recognized difficulties, the proposal is to continue with

Elective Two for the change of N third Road and N fourth Road into two-way streets.

Elective Two offers a more comprehensive way to deal with tending to somewhere safe
