Modernizing I-270

The I-270 North Project is the next step toward improvements along interstate 270 from I-70 on the west to the Chain of Rocks Bridge on the east. This follows the completed I-270 North Environmental Assessment (EA) that addressed impacts of congestion, safety, and mobility, as well as accessibility and aging infrastructure, along I-270. The Federal Highway Administration (FHWA) determined that the Preferred Alternative for the I-270 North EA will have no significant impact on the area. This meant the Missouri Department of Transportation (MoDOT) was able to move to the next step for improving I-270. The Missouri Highways and Transportation Commission approved the I-270 North project to be procured using Design-Build in the summer of 2018.
