I-75 will be closed in both directions this weekend in Southwest Detroit due to bridge construction. The freeway will be closed from Springwells Street to Clark Street from around 11 p.m. Friday evening until 5 a.m. Monday morning. Both the Vernor Highway on-ramp to southbound I-75 and the Ambassador Bridge on-ramp to southbound I-75 will be closed as well. These closures are due to the interchange for the Gordie Howe International Bridge being built.
