The Pennsylvania Turnpike Commission is sending out another traffic reminder that a detour that could add more than an hour to travel times will be in place on the Pennsylvania Turnpike this weekend as crews demolish and replace a bridge in New Sewickley Township. The turnpike will completely close to traffic at 9:00 tonight between the Beaver Valley and Cranberry exits. The closure is necessary for crews to tear down and replace the bridge that carries the turnpike over Brush Creek. The closure will last about 55 hours and is scheduled to repopen Monday morning at 4am.
