Starting April 11, the ramps from westbound I-475 to Douglas Ave. and from Douglas Ave. to eastbound I-475 will be closed.
The closure is necessary to facilitate the ongoing upgrades to the I-475/I-75 interchange.
The Ohio Department of Transportation recommends that motorists use Secor Rd. to and Monroe St. as detours.
A new ramp from Promedica Parkway is now open. The ramp from Upton Ave. to I-475 is permanently closed.
The construction project to improve access to the Toledo hospital and Promedica facilities and to improve the interchange of I-475 and I-75 are expected to last through 2012.
