In light of rapid growth in Philadelphia's northwest suburbs, Pennsylvania Turnpike officials sought a low-maintenance, cost-effective solution for increased traffic volume at its Valley Forge interchange. The answer was a $48-million project that aims to relieve traffic congestion in Chester County by building the turnpike's first four-direction, all-electronic toll interchange.
The project's scope called for building new east-bound and westbound exit and entrance ramps, three retaining walls and two electronic tolling facilities, plus widening the freeway and creating a monitoring system.
