Why is MoDOT doing this project?

The interchange, built in 1969, is near the end of its life and the bridge is due for replacement within the next several years. The interchange is highly congested and there are currently no pedestrian or bicycle accommodations. Surrounding land development is underutilized or undeveloped and is ripe for economic growth if we have adequate transportation infrastructure.

How will this project benefit me?

The Route 291 Interchange at US 50 is currently over capacity and requires significant maintenance, including bridge replacement. This project will ease congestion, enhance transportation safety and accommodate future growth.

The proposed interchange improvements include:

  • reconstructing the Route 291 overpass bridges into a diverging diamond design.
  • The intersection of Blue Parkway, the north outer road to US 50 Highway, and Jefferson Street will be reconstructed as a roundabout.
  • Oldham Parkway will be realigned to the south and the existing traffic signal controlled intersection will be removed.
  • There will be an auxiliary lane added on WB 50 connecting the Route 291 on-ramp to the 3rd Street off-ramp.
  • See the concept here.

This project will also accommodate bikes and pedestrians. One of the busiest park facilities in the community with indoor and outdoor recreational amenities is located at the northeast corner of the interchange. The project will include off-street shared-use trails to enhance connectivity of pedestrians and cyclists.
