The final bridge on I-70 takes more time than anticipated

COLUMBIA - The Missouri Department of Transportation was sliding the third new bridge in place on I-70 Monday at Business Loop 70. It is expected to open to traffic in 30 days.

Danny Roeger, a construction inspector with MoDOT, said the latest part of the project was off to a rough start.

"This morning we had a few delays, some prep work that took longer than anticipated, but also the structure itself is roughly twice the size the other two bridges we previously slid. It's just a little more bulky, a little more weight to move. It's just taking a little more time," Roeger said.

He said the workers were moving the bridge about five feet per hour, which is slower than the bridges at Garth Avenue and Rangeline Street.

"The bridge will support all four lanes, two lanes on each direction of I-70 traffic," Roeger said.

The other two bridges only have two lanes.

The bridge was slid in place about 10 p.m. Monday. It was originally scheduled to be slid in place by 5 p.m.

Roeger said using dish soap to move the bridge is cost-efficient.

"Build the bridge off to the side out of traffic, and without any impact to traffic, and build this new footings and just slide the bridge onto those footings. And all we have to remove, moving forward, is only the temporary footing under the bridge," Roeger said.

Roeger said the bridges on I-70 are no longer serviceable and tough to maintain. The three new bridges are expected to serve 50 to 80 years.

He said the entire construction work is expected to be complete early this fall.
