The Midway Interchange area and Grant Marsh Bridge connect I-94, I-194, and Bismarck and Mandan. The existing bridge and interchanges were constructed with the surrounding Interstate system, which has not experienced major improvements since it was originally built in 1965.
The bridge is reaching the end of its useful life and will need replacement in the future. This provides an opportunity to consider operational improvements for the I-94 and I-194 roadways and ramps. These Interstate improvements would work jointly with replacement alternatives for the Grant Marsh Bridge.
This Study will provide project-level analyses and early decisions that follow Federal Highway Administration (FHWA) guidance under the Planning and Environment Linkages (PEL) initiative. More information on PEL studies can be found at: www.environment.fhwa.dot.gov/env_initiatives/PEL.aspx
The purpose of this study is to determine alternatives that improve traffic operations, increase capacity, reduce driver confusion, and maintain a uniform freeway system. By following the PEL Study process, transportation planning is connected with environmental community concerns. At the conclusion of this feasibility study, a project will be incorporated into the federal environmental review process.
A public input meeting will be held on Thursday, December 7, 2023 from 5:30 to 7:30 p.m. with a presentation at 6 p.m. This meeting will be held at the Morton Mandan Public Library (600 W. Main Street, Mandan, ND 58554). At this meeting individuals will be shown traffic, safety, and environmental considerations, and asked to provide feedback on the preliminary purpose and need, range of alternatives, and conceptual solutions.
Comments are requested via email or comment card by Friday, December 22nd. Meeting materials will be posted to the project website on Thursday, December 7, 2023.

The Civil Rights Act of 1964 and related nondiscrimination authorities require the North Dakota Department of Transportation to ensure everyone has the opportunity to comment on the transportation programs and activities that may affect their community. To help with that, we ask that you respond to the following questions. You are not required to disclose the information requested in order to participate. Any information provided to the NDDOT will be retained solely for the purpose of collecting statistical data to ensure inclusion of all segments of the population affected by transportation programs and activities.
The first public input meeting was held on Monday, June 5, 2023 at the Huckleberry House in Bismarck, ND. At this meeting individuals were provided project background information and asked to provide feedback on existing conditions, concerns, and opportunities within the project area.
The project is located along I-94 from Exit 153 in Mandan to Exit 157 in Bismarck. This area encompasses the Midway interstate system and Grant Marsh Bridge. It is the main area being analyzed for traffic operations. This study will develop alternatives for this area.
The study area encompasses the project location and various ramps and segments of the surrounding roadways. The purpose of studying this larger area is to understand how different alternatives within the project location will impact the greater roadway network.
