MDU will be removing overhead lines on Sunday, March 30 at three locations along Memorial Highway: 46th Ave, 40th Ave and just west of the Kia dealership. Traffic will be stopped for around 5 minutes per location to safely remove the overhead lines. Please use caution and be prepared to stop when in the area on Sunday, March 30.
3/27/25 Temporary closure of 19th Street SE in Mandan begins Apr. 1
3/17/25 Construction Update. Memorial Highway construction will begin around April 1. Traffic will be reduced to a single lane in each direction during construction, the speed will be lowered to 25 mph, and there will be an 11-foot width restriction.
Memorial Highway will be reconstructed from 32nd Ave SE to 46th Ave SE as part of the 2025 construction season. The project includes replacing the existing surfacing with new concrete pavement, improving drainage, installing underground utilities, and a new multi-use path for bicyclists and pedestrians.
Other improvements include upgraded traffic signals, lighting, improved access for businesses, and drainage enhancements. The east half of the Memorial Highway reconstruction is expected to be completed by mid-November, and the east side multi-use path is scheduled for completion in 2026.
Upcoming Work. Project improvements include construction of an underground storm sewer trunk line that will cross 21st St SE and 19th St SE. Information regarding street closures and proposed detour routes is available here: 19th St SE (starting Apr. 1, 2025), 21st St SE (April 2025).

The Memorial Highway Reconstruction project is a two-phase project, anticipated to take three years to complete:
During construction, the roadway will remain OPEN with at least one travel lane in each direction and a center turn lane. Access to all businesses will remain open during the construction years as well.
Project Overview. Full-depth reconstruction of Memorial Highway from Main Street to the Memorial Bridge including:
- transitioning from an asphalt to concrete surface
- adding sidewalks to the NE side of the corridor and a shared use path to the SW side of the corridor
- improving traffic flow and intersection safety
- improving drainage
- providing safe access to businesses
- addressing pavement at the end of its useful life
- underground sanitary sewer and water line improvements
- MDU will bury current above-ground lines along the corridor.
Financial Breakdown. The project is now estimated at $119M. The federal and state contributions to this project are estimated at $89M. The remaining $30M will be paid through a combination of funds including a City-wide speical assessment and a tiered, localized utility assessment.

Special Assessment District. There are two parts to the special assessment district: a tiered, localized special assessment district and a City-wide special assessment district:
- The tiered assessment is for properties located either on-corridor or just off the corridor with a greater benefit from the project than the rest of the community.
- A City-wide special assessment is being used for roadway and storm sewer improvements as most all people in the city of Mandan use and/or benefit from the roadway. The anticipated city-wide assessment is $500 per parcel paid back over a 20-year period (which is approximately $25/year).
Information on the special assessment district was noticed in the Oct. 4 Mandan News newspaper. Tier 1 and Tier 2 property owners will soon receive a letter in the mail with information on the street improvement district, estimated costs and protest period. A 30-day protest period began Oct. 4, 2024. Residents may submit a letter of protest to the Engineering Department by 4:30 p.m. on Monday, Nov. 4. Consideration of sufficiency of protests and a public hearing are scheduled for the Nov. 5 City Commission meeting at 5:30 p.m.
Final distribution of assessments will be determined by the City Commission at the conclusion of the project, after review and approval by the Special Assessment commission (anticipated in 2028).
