The Michigan Dept. of Transportation hopes to expedite rebuilding of a new overpass over Interstate 75 north of Detroit, to replace a five-lane steel-girder structure that collapsed on July 15 from a fire caused by a tanker truck that crashed into it. Posen Construction Inc., Detroit, removed debris in a $78,000 contract, says MDOT spokesman Robert Morosi. Locally based Cadillac Asphalt LLC removed the top 3 in. of asphalt on I-75 and put in 450 tons of new pavement under a $90,000 contract. The highway was reopened on July 20. MDOT will seek bids for a new overpass in September.
