Motorists traveling the Pennsylvania Turnpike in the Breezewood area late Saturday and early Sunday will be forced to take a detour.

Both directions of the 65-mile stretch between Breezewood Exit 161 and Carlisle Exit 226 will be closed to allow a contractor to demolish two bridges that carry local roads over the turnpike in Cumberland County.

Beginning at 11 p.m. Saturday, all eastbound traffic will have to exit at the Breezewood Interchange in Bedford County. At 11:45 p.m., all westbound traffic will be forced to exit at the Carlisle Interchange in Cumberland County.

Detour directions will be given to exiting motorists by tollbooth operators.

Westbound motorists exiting at Carlisle will follow Route 11 North to Interstate 81 South into Maryland to Interstate 70 West to Route 30 East, re-entering the turnpike at Breezewood.

Eastbound motorists exiting at Breezewood will follow Route 30 West to Interstate 70 East to Interstate 81 North to Route 11 South, re-entering the turnpike at Carlisle.

The detour is estimated to add 30 minutes of travel time and 33 miles to the trip. The turnpike is scheduled to reopen to one lane in each direction by 4 a.m. on Sunday, and traffic should be fully restored by 8 a.m. Sunday.

The bridges, which carry Bloserville Road and Old Mill Road over the turnpike in West Pennsboro Township, are the first of four along the turnpike scheduled to be replaced.
