COLUMBIA — The Route B bridge over Business Loop 70 will close for demolition starting Friday.
The bridge will close at 6 a.m. in preparation for demolition, according to a Missouri Department of Transportation news release. The demolition will occur over the weekend, from Friday to Monday. It will remain closed until Sept. 15 while a new bridge is built in its place.
A portion of Business Loop 70 from Old 63 to College Avenue will also be closed while the bridge is being taken down.
Kirsten Munck, assistant to the resident engineer at MoDOT, said the demolition should only affect traffic on Business Loop 70 from 10 p.m. Friday until 5 a.m. Monday.
The road should be fully reopened by rush hour Monday morning, Munck said.
During the construction of the new bridge, businesses along Route B and Business Loop 70 will still be accessible. However, Route B from Hathman Place to Ammonette Street will be closed for the duration of the construction.
There are detour options available for drivers and Munck said MoDOT is putting up a stop sign at the intersection of Ammonette Street and Old 63 to help control the flow of traffic. A temporary traffic signal will also be placed at Route B and Hathman Place to help manage the expected traffic until the new bridge is complete.
The bridge is being built by APAC-Missouri using a technique known as geosynthetic reinforced soil. This bridge-building method is much faster and cheaper than traditional techniques, according to the release. Munck said this was the first bridge of its kind to be built in the state.
Without the need to drive expensive bridge piles, the geosynthetic technique saves time and resources, the release said. The $881,239 bridge is being partially funded by a federal grant in order to test the geosynthetic method.
