The Columbia I-70 Bridges Project is an $18 million design-build project to replace the I-70 bridges over Business Loop 70/West Boulevard, Garth Avenue, and MO Route 763/Rangeline Street in Columbia, Mo. Design-build is a project delivery method that combines both the design and construction phases into one contract to save time and resources.
Business Loop Bridge Slide
Here’s a time-lapse video of the bridge slide and other work at Business Loop this past week:
Traffic Impacts Week of
Contractor Emery Sapp and Sons is on schedule to finish work on the new
Business Loop 70/West Boulevard interchange on the evening of July 27. Business
Loop and all ramps will open on July 27.
Until then, all on- and off- ramps at Interstate 70 and Business Loop remain closed.
Those heading to Cosmo Park for the Show Me State Games this weekend (July
22-24) should use Stadium Boulevard as an alternate route. In addition to
Stadium, travelers can use Providence Road and Bernadette Drive to get to shops,
restaurants and other destinations along Business Loop.
When completed, the new Business Loop interchange will include two dual-lane
roundabouts on the north and south sides of I-70, improved access to I-70 Drive
SW and decreased traffic delays on Creasy Springs.
Median barrier near Range Line St. along I-70 will be finished Monday, 8/1

Rangeline, Garth Pedestrian Detours
The sidewalks along Rangeline Street (Route 763) between Interstate 70 and Vandiver Drive in Columbia will remain closed for several months as construction takes place.
Pedestrians and bicyclists are advised to detour around the closed sidewalks by taking Business Loop 70 to Providence Road to Vandiver Drive.
Pedestrians can also use Columbia’s public transit system, COMO Connect, to travel through the area. The Co-Mo Connect Black Connector has stops at Boone Electric Cooperative and Rangline on the south side of I-70 and at Rangeline and Vandiver on the north side of I-70.
The sidewalks along North Garth Avenue between U.S. Route 40 and Interstate 70 will remain closed until next summer as construction takes place.
Pedestrians and bicyclists are advised to detour around the closed sidewalks by taking N. Providence Road to E. Texas Avenue.
Maps of Rangeline and Garth pedestrian detour routes, as well as the Black Connector route, are below.
