Indiana, PA – The Pennsylvania Department of Transportation (PennDOT) is announcing an upcoming overnight detour on Interstate 79 Northbound and Southbound in Muddy Creek Township, Butler County as crews demolish a portion of the existing overhead State Route 488 Portersville Bridge.

Beginning at 8:00 PM on April 13, crews from J.F. Shea Construction, Inc. of Mt. Pleasant, PA, will be demolishing the first stage of the existing structure with work continuing overnight until 6:00 AM April 14. Following the April 13-14 detour, two-lane traffic on State Route 488 will be maintained throughout the project.

To detour, motorists travelling north on Interstate 79 should exit at the Exit 96 off-ramp and then get back onto Interstate 79 via the Northbound on-ramp.  Southbound, motorists should take Exit 99 to U.S. Route 422 Westbound to U.S. Route 19 Southbound to State Route 488 Eastbound to Interstate 79 Southbound.

Work is weather dependent. 

The anticipated completion date for this $6.3 million bridge replacement project is June 2024. The existing bridge will be replaced with a two-span, steel bridge.
