About The Study

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
