The Jefferson bascule bridge over the Rouge River will close to traffic from 9 a.m. to 9 p.m. Sunday, Wayne County officials said.
The bridge will be closed for repairs to the bridge's steel deck, they said.
Despite scheduling the work to be done outside of rush hour traffic, they also said motorists should be prepared for delays and be aware of the detour.
Northbound Jefferson Avenue traffic will be routed to Schaefer Highway, then to Fort Street, from Fort to Dearborn Street and back to Jefferson.
Southbound Jefferson traffic will detour to Dearborn, then to Fort and to Schaefer before returning to Jefferson.
Built in 1922, the 248-foot-long bridge is a double-leaf, fixed trunnion bascule bridge, or drawbridge.
Located south and east of Interstate 75, the Jefferson Avenue drawbridge is a heavily traveled crossing between Detroit and River Rouge. It's owned and maintained by Wayne County.
In May 2013, a bridge operator lowered it onto a 670-foot freighter that had been cleared to pass. Police later determined the operator was drunk.
The bridge was repaired and reopened in August 2016.
