Michigan’s first network-tied arch bridge

The brand new Second Avenue construction is the primary network-tied arch bridge inbuilt Michigan.

The Second Avenue bridge was initially inbuilt 1954 and has by no means been changed.

Community refers back to the cables which can be crossed from the highest of the arch to the underside of the driving floor on each side of the construction. The design makes it so a middle pier isn’t needed, which is able to accommodate the long run I-94/M-10 interchange.

The skeleton of the bridge was constructed off-site on the Wayne State College Palmer car parking zone. Whereas the skeleton was constructed, crews labored on-site constructing the bridge basis and abutment partitions alongside the I-94 freeway.

Crews will use self-propelled modular transporters (SPMTs) to maneuver the skeleton of the bridge throughout the freeway. The skeleton will likely be secured into the brand new bridge helps on either side of I-94. The skeleton weighs 1,100 tons.

After the bridge has been moved, a brand new driving floor will likely be constructed on the skeleton of the bridge. There will likely be extra closures earlier than the bridge opens to site visitors.

The Second Avenue bridge is predicted to reopen to site visitors this fall. Click on right here to study extra.
