Sixteen miles of lane restrictions on Interstate 79 bridges will affect Butler County motorists for the next month.

According to a news release from the Pennsylvania Department of Transportation, work will be done on three bridges on I-79, between exits 88 and 105.

The work will restrict travel lanes starting at 7 p.m. Sept. 30 and will last, weather permitting, until 3 p.m. Nov. 1.

PennDOT says the work being done on the project — which includes milling, patching and repaving the four-lane interstate, new guiderails and new painting and line delineation — will cost a total of $25.8 million. The release also stated the work is being done by Glen O. Hawbaker of State College.
