TRAFFIC ALERT: Complete closure of I-94 in Detroit through Tuesday AM — What to know

75756A5E-120A-4932-810C-2FD980DB785E

DETROIT (WWJ) – Drivers in Detroit are dealing with a big detour, beginning Thursday morning, as the Michigan Department of Transportation continues work on the Second Avenue bridge.

Back in July MDOT crews moved the network tied arch bridge over I-94, the first of its kind built in the state. Now crews have started post-tensioning work to reinforce the cables that support the bridge's driving surface for vehicular traffic, non-motorized components, and barrier walls.

MDOT began closing the four-mile stretch of I-94 between I-75 and I-96, at 4 a.m. on Thursday, Sept. 29.

It is scheduled to reopen at 4 a.m. on Tuesday, Oct. 4.

Officials say the full closure is needed for worker and public safety to allow inspectors full access to monitor the structure during the post-tensioning process.

Here’s what you need to know about the closure:

• Starting at 1 a.m. on Sept. 29, all entrance ramps to eastbound I-94 will be closed from 30th Street (just west of Warren Avenue) to Chrysler Drive.

• All entrance ramps on the westbound side will be closed from Mt. Elliott Street to Trumbull Avenue.

• Weather permitting, the freeway and ramps will be reopened by 4 a.m. on Oct. 4.

• During the closure, EB I-94 traffic will be diverted to EB I-96, then northbound I-75 and back to EB I-94.

Westbound traffic on I-94, meanwhile, will follow I-75 south, then WB I-96 back to WB I-94.

The new network tied arch bridge, which was built in a parking lot at Wayne State University, is replacing the original Second Avenue bridge, which was built in 1954 and has never been replaced.

Network refers to the cables that are crossed from the top of the arch to the bottom of the driving surface on both sides of the structure.

More information on the Second Avenue bridge project, including photos of the new structure, is available on the I-94 modernization project website.
