History
The utility of constructing a cross-town expressway through Detroit was recognized as early as the 1920s. Planning continued off and on through the early 1940s, when the state began anticipating post-war projects. Originally called the "Crosstown Expressway," the Detroit City Council approved a petition to rename the proposed stretch the "Edsel Ford Expressway" in April 1946. The 14-mile (23 km) Edsel Ford would ultimately require the construction of over 70 structures, of which the US-12 bridges are two.[2]
Work began on the freeway in 1948, starting on the Detroit–Dearborn border, with the US 12 bridges being the first structures opened for bidding. The firm of Darin & Armstrong won the construction contract with a bid of $925,000, and began work in August 1948. The bridges were completed by August 1949. A ribbon cutting ceremony, presided over by State Highway Commissioner Charles Ziegler, was held on August 17.[2]
Description
Of the two bridges, the span over I-94 is the longer. The shorter span over the westbound I-94 ramp is 50 feet (15 m) long and 90 feet (27 m) wide. The bridge has eighteen stringers, more closely spaced in the center of the deck to support what once was a streetcar line. Channels are laid over and riveted onto the stringers. The railing, installed in 1967, has a precast base and horizontal pipe.[3]
