On Oct. 1 the city will begin a six-week rehabilitation of the northbound on-ramp to Lake Shore Drive from Michigan Avenue at Oak Street.
The $1.78 million project will close the ramp while repairs are made to the nearly 50-year-old viaduct and retaining walls where traffic is brought under the roadway before merging onto the northbound Lake Shore Drive, according to the Chicago Department of Transportation.
Northbound traffic will be rerouted along Inner Lake Shore Drive for a mile to LaSalle Drive, where vehicles can get onto Lake Shore Drive. Traffic control aides will be deployed and adjustments will be made to traffic signals along the detour route.
Southbound traffic exiting Lake Shore Drive at Michigan and Oak will not be affected, but there could be temporary nighttime lane closures in both directions on Lake Shore Drive on the top side of the viaduct for needed repairs.
The city knows there will be traffic delays but say it can't be helped because the viaduct needs immediate repairs. Officials said they are working with area residents and businesses, along with the Chicago Transit Authority, to prepare for the project.
“This repair project is necessary due to the deteriorated condition of the concrete of the viaduct deck and retaining walls of the ramp, which has not seen any significant rehabilitation since its original construction in 1963,” CDOT Commissioner Gabe Klein said in a release. “We want to complete this repair work immediately before another winter cycle of freezing and thawing, as well as additional damage that could come from the use of road salt.”Copyright © 2015, The Baltimore Sun
