Detroit, MI - After successfully completing post-tensioning work on the new Second Avenue bridge over I-94 in Detroit, crews will reopen the freeway at 4 a.m. Tuesday, Oct. 4.
The work required closing both directions of I-94 between I-75 and I-96 for five days.
Upon reopening the freeway, crews will keep the left lane closed on eastbound I-94 from I-96 to M-10 (Lodge Freeway) for ongoing bridge work at Grand River Avenue and the M-10 interchange. The single lane closure, and the ramp closures at the I-94/I-96 interchange, are expected to be removed by the end of October.
Post-tensioning was required on the new Second Avenue structure to reinforce the cables that support the bridge's driving surface for vehicular traffic, nonmotorized components, and barrier walls.
The new Second Avenue structure is the first network tied arch bridge built in the state of Michigan. 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.
The Second Avenue bridge was originally built in 1954 and has never been replaced. Additional information on the Second Avenue bridge can be found here.
