Why are portions of M-6 crumbling, and what is the state doing about it?
In 2004 the Michigan Department of Transportation spent $370 million constructing the South Beltline. The warranty on the surface expired before sections of the freeway began to fail. Three years from now MDOT will resurface two, three mile sections of M-6 where seams are prematurely deteriorating.
The state called on Dr. Peter Taylor, director of the National Concrete Pavement Technology Center, to find out what can be done to improve state roadway surfaces.
