About The Project
NDDOT expects to break ground on the I-94 Interchange (Exit 161) Reconstruction project in spring of 2024, with construction estimated to run through the summer of 2026. The interchange reconstruction project is designed to support growth in this area of Bismarck and relieve what has become an increasingly congested corridor along Centennial Road/Bismarck Expressway and I-94. NDDOT has worked closely with the City of Bismarck, local business owners, and the general public to find a traffic solution that would benefit the entire community. The modified single-point urban interchange (SPUI) selected for this project will efficiently move large volumes of traffic by converging traffic under one set of traffic signals.
