History & significance

The Dean Parkway Bridge is a reinforced-concrete, cast-in-place slab constructed in 1912. The former Chicago, Milwaukee & St. Paul Railroad bridge features a concrete parapet with Classical Revival details, including recessed panels and circle medallions centered on each span. It currently carries Midtown Avenue over Dean Boulevard. The Dean Parkway Bridge is significant as a contributing resource to the determined-eligible Grand Rounds Historic District.

 

Rehabilitation activities

Dean Parkway BridgeHennepin County Housing, Community Works, and Transit, with assistance from the Federal Highway Administration, rehabilitated Bridge 90661 in 2011. The rehabilitation included repair of deteriorated concrete on the bridge parapet railing, piers, and abutments. To repair areas of deterioration, the contractors utilized shotcrete, a construction technique that involves spraying concrete onto the bridge surface. While the material was wet, saw-cut wood boards were pressed onto the new concrete surface to replicate the historic concrete wood-board formwork pattern. After curing, the concrete was stained to match the original color.
