Medora Business Loop and City Section

Construction on the Medora Business Loop and City Section project began in fall 2024 and will continue through summer of 2026. The infrastructure enhancements will improve safety, traffic flow, and pedestrian access along Pacific Avenue (I-94 Business Loop) between exits 24 and 27. The work is vital as Medora prepares for the Theodore Roosevelt Presidential Library opening and the additional traffic it will bring to the city.

The NDDOT has worked closely with city officials, local business owners, and the public to develop a traffic solution that benefits the entire community.

Key features of the project include:  

• Roundabout installation to improve traffic flow at Pacific Avenue and Chateau Road.
• Bridge widening to expand the Little Missouri River bridge including a left-turn lane and a shared-use path.
• Roadway upgrades, including fresh pavement along Pacific Avenue from I-94 Exits 24 to 27, decorative lighting and landscaped medians in select areas.
• Pedestrian accessibility and ADA enhancements, including new crosswalks and upgraded pedestrian ramps.
• Chateau Road reconstruction, including a shared-use path, new signage, a center turn lane and other roadway upgrades.

Construction Progress

To minimize disruptions, work will not take place in the city center from May 22 to September 3, 2025. Construction on the new roundabout, Little Missouri River Bridge, and Pacific Avenue widening just east of the bridge will continue throughout the summer.

• Pacific Ave (Little Missouri Bridge to East River Rd N): Road widening is in progress for future connection to the expanded bridge. Construction of the Shared Use Path (SUP) will begin the week of July 21.
• City Section Improvements: New curbs and gutters will be added to the west side of East River Rd N. Construction of the Chimney Park entrance is complete.
• Little Missouri Bridge & Roundabout: Girder placement is set for the week of July 21. Work on the SE corner of the roundabout is paused until the north side of the bridge is completed this fall.
• Chateau Road: Earthwork operations for the construction of new alignment areas and temporary bypasses are in progress. Concrete paving will start early August.

• The Pacific Ave/Chateau Road roundabout is open to traffic. Pedestrians can use the new north sidewalk.
• Expect short-term traffic impacts on Pacific Ave as materials are delivered for bridge girder placement the week of July 21.
• Chateau Road traffic is open to two lanes, with flaggers onsite to guide traffic as needed. All operations stop before 4 p.m. to accommodate pitchfork fondue and musical traffic.
