Columbia I-70 Bridges Project

The Columbia I-70 Bridges Project was 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.

Ceremony Marks Completion of Columbia I-70 Bridges Project

How do you keep 80,000 vehicles a day moving on a cross-state interstate while replacing several aging and deteriorating bridges and improving two major interchanges?

That’s the challenge the Missouri Department of Transportation, Emery Sapp and Sons and Parsons faced with the Columbia I-70 Bridges design-build project.

A ribbon-cutting ceremony was held Aug. 26 to celebrate the completion of the $18 million project, which began last August and was completed one year later, about two months ahead of schedule. (MORE)

Driving a Dual-Lane Roundabout

What is a Roundabout?

  • A roundabout is an intersection that accommodates traffic flow in one direction around a central circular island.  It is used as a form of intersection control, like traffic signals or stop signs.                                                

Why Roundabouts?

  • Roundabouts increase safety and improve traffic flow.
  • They allow for free flowing traffic with yield conditions that reduce crashes by as much as 75 percent.

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.
