MIDLAND (WJRT) (2/2/2018) - Part of the M-20 bridge over the Tittabawassee River in downtown Midland will be closing Monday for the start of an 18-month project to replace it.
One lane of the eastbound span will be closed next week while crews complete a pavement project before that side is reconfigured to carry traffic in both directions over the river.
The Michigan Department of Transportation is beginning a $21 million complete demolition and reconstruction of the bridge, which isn't scheduled for completion until September 2019.
Sometime before Feb. 13, all traffic on M-20 will shift to the eastbound side of the bridge and the westbound side will be demolished. The new bridge will be rebuilt in phases from the foundation up.
When the new westbound side of the bridge is complete sometime in the fall of 2018, all traffic will shift to that side so the eastbound side can be demolished and rebuilt.
Traffic will be limited to one lane in each direction during the project.
Left and right turns from Jerome Street onto Larkin and Main streets in downtown Midland will be restricted during the project. A signed detour route will be provided for motorists entering and leaving the downtown area.
In addition to the lane closures, the Pere Marquette Rail Trail will be closed under the M-20 Bridge beginning Feb. 12 through the duration of the project. The Chippewassee Park Loop will have intermittent closures as construction activities warrant.
A signed detour route for the rail trail will be provided, which will direct rail trail users to utilize Ashman and Main streets to get around the closure.
Electrical power will be shut off at Chippewassee Park and Trilogy Skate Park from Feb. 12 through May 2018 to facilitate work by Consumers Energy related to the project.
