About The Project
Construction on the Medora Business Loop and City Section project began in fall 2024 and will occur in multiple phases until its projected completion in the 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 especially vital as Medora prepares for the opening of the Theodore Roosevelt Presidential Library 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. To minimize disruption during peak tourist season, work will not take place east of East River Road N (Park Entrance) and west of 6th Street from May 22 to September 3, 2025.
Key features of the project include:
- Roundabout installation to improve traffic flow at Pacific Avenue and Chateau Road with a new roundabout.
- 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.
Project Updates
Watch for construction workers and equipment. Sections of Pacific Avenue, from Chimney Park Road to Pool Drive, have been widened. Traffic has been shifted to the southern portion of the new widenings, creating a safe work zone on the northern side for construction on the Little Missouri Bridge and the new roundabout at Chateau Road. Two-way traffic remains in place throughout the project.
Medora Community Center Entrance: Construction of a new driveway is underway to align with E. River Road S. The existing driveway will be removed once the new one is complete. Work will take two weeks.
Chimney Park Entrance/ E. River Rd N.: Crews will grade and build a new Shared Use Path (SUP) at Chimney Park Entrance, plus install curbs and gutters on the west side of E. River Rd N. Work will proceed in phases starting the week of April 21. Two-way traffic will be maintained along Pacific Avenue.
Pacific Avenue & 6th Street: Culvert installation in progress. Expect one-lane traffic with flaggers directing traffic for a brief period.

Frequently Asked Questions
Will there be a sign in the middle of the roundabout?
A “Welcome to Medora” sign will be installed as part of the project. The design and aesthetics were developed in consultation with members of the city council.
How long will the current temporary traffic control roadway be like it is?
The temporary roadway will remain in place until portions of the Little Missouri bridge are widened, and the roundabout is complete, which is expected by late summer or early fall. Lanes will stay 11 feet wide.
How will construction and traffic control impact summer events?
Crews will update pavement markings at the Chateau Road intersection and coordinate with the Billings County Sheriff’s Department for safe traffic control during the Medora Musical season. NDDOT will coordinate logistics with the contractor for the annual All Horse Flag Parade. Pile driving is expected to be completed by summer, minimizing construction noise.
