SCOPING REPORT A. GENERAL INFORMATION

Project Number: District: Williston Highway: 23 Location: Approximately 4.5 Miles to 8 Miles West of New Town Reference Point: RP 41.30 to RP 44.60 Counties: McKenzie Legal Description: T152N, R94W, Sec 23 to T152N, R93W, Sec 16 Functional and Funding Roadway Classification: State Corridor National Highway System: Yes Speed Limit: 65 mph – RP 41.30 to RP 43.87 45 mph – RP 43.87 to RP 44.60 Freight Level: 1 Project Schedule: Proposed to be added to the STIP as a Safety Project.

B. PURPOSE, NEED, AND IMPROVEMENT Purpose and Need of Project: Public concern about turning movements in passing and climbing lanes prompted NDDOT to do a safety study of those areas, and the ND 23 corridor west of New Town was identified as having turning-related crashes. For this report, three intersections of ND 23 are being proposed for safety improvements: 97th Ave NW, 95th Ave NW, and Chief Four Bears Ave. A Traffic Operations study was conducted in October 2018 and the following recommendations were made:

1. Install WB left and right turn lanes and EB left and right turn lanes at ND 23 and 97th Ave NW. Install destination lighting at the intersection of ND 23 and 97th Ave NW.

2. Install WB left and right turn lanes and EB left and right turn lanes at ND 23 and 95th Ave NW. Install destination lighting at the intersection of ND 23 and 95th Ave NW.

3. Install EB left turn lane and lengthen existing WB right turn lane at ND 23 and Chief Four Bears Ave.

There is an existing WB passing lane through the intersection of ND 23 and 95th Ave NW. Also, the intersection of ND 23 and Chief Four Bears Ave currently has illumination lighting on the north side of the roadway which illuminates the existing WB right turn lane. Additional recommendations were made regarding any future projects pertaining to the above recommendations:

• It is recommended that the turn lanes be designed according to section III-03.05.01 of NDDOT’s Design Manual with an L4 storage length of 100ft for left turns and zero feet for right turns.

2

• If an EB left turn lane is added at the intersection of ND 23 and Chief Four Bears Ave., it is recommended that the existing lighting be extended to the west of the intersection.

The intersection of ND 23 and Chief Four Bears Ave. is located near a portion of Lake Sakakawea reservoir and adding an additional turn lane might impact the reservoir. Due to this and limited right of way, an additional option to install a bypass lane is proposed to limit the roadway footprint and still add operational improvements. Proposed Improvements: 1. Turn Lanes at 97th Ave NW: It is proposed to install left and right turn lanes in both east and westbound directions at 97th Ave NW and add destination lighting.

3

2. Turn Lanes at 95th Ave NW: It is proposed to install left and right turn lanes in both east and westbound directions at 95th Ave NW and add destination lighting.

3A. Turn Lanes and Lighting at Chief Four Bears Ave: It is proposed to install an EB left turn lane, lengthen the existing WB right turn lane, and extend the existing illumination lighting to fully illuminate the turn lanes.

3B. Bypass Lane and Lighting at Chief Four Bears Ave: It is proposed to install an EB bypass lane, lengthen the existing WB right turn lane, and extend the existing illumination lighting to fully illuminate the turn lane and bypass lane.

PCE = Passenger Car Equiva lent.

Warrant 1.A i s traffic volumes . Warrant 1.C i s engineering judgment. Warrant 2.A i s engineering judgement ≤ 45 mph.

Warrant 1.C was used turn lanes , due to the volumes being just under the threshold and the recommendation of a WB left turn lane.

Warrant 2.A was used for a right and left turn lane with the assumption traffic travels > 50mph and there i s an exis ting right turn lane.

Warrant 1.B i s when there have been 2 crashes in 3 years of crash types susceptible to correction by a turn lane.

Crash Analysis: 1. Turn Lanes at 97th Ave NW: The study period was 01-01-2013 to 12-31-2017

• There were no fatal crashes. • There were 3 rear-end and 2 angle crashes. • 80% of crashes occurred during daylight conditions. • All crashes occurred on dry surface conditions

2. Turn Lanes at 95th Ave NW: The study period was 01-01-2013 to 12-31-2017

• There was one fatal crash: A semi (V1) was making a WB to SB left turn from the WB passing lane when it side-swiped a WB V2 attempting to pass it on the left (EB lanes). The driver of V2 was ejected.

• There were 5 side-swipe same direction and 3 rear-end crashes at this location.
