invest $1.1 million to make structural steel repairs and replace the underwater cable providing power and control to both sides of the US-31 bascule bridge in Charlevoix. This project also will include replacement and upgrade of electrical components that control the bridge’s various mechanical systems.
This work will primarily require single-lane closures and traffic shifts, with one lane open in each direction, except for:
– The bridge will be closed to traffic for two nights between 11 p.m. and 5 a.m. on two dates that have not yet been scheduled. During those closures, traffic will be detoured on US-31, US-131, M-32, and M-66. Closures will be announced in advance. Those closures are expected to occur the nights of Tuesday, Jan. 7, and Wednesday, Jan. 8, weather and work progress permitting.
– During installation of the underwater cable and limit switches, intermittent nighttime testing of the bridge will occur, resulting in closures to traffic of up to 15 minutes.
This project includes upgrades and repairs to the bridge’s structural steel and electrical components, designed to extend its service life and maintain reliability.
