This project involved reconstruction of approximately one mile of the PA Turnpike on a new alignment with a maximum divergence of approximately 66 feet to the south. Staged construction of the mainline structure was employed to maintain four lanes of traffic at all times during construction. W.E.C. Engineers, Inc. provided final design for the replacement of the Viaduct and also performed shop drawing review and construction consultation. The reconstruction efforts included:

• The construction of a 594 foot-long, 5 span continuous curved girder bridge

• A 1,000 foot-long soil nail anchored retaining wall

• A 230 foot-long extension to an existing culvert

• The resurfacing of 1,800 feet of turnpike immediately east of the realignment

• Demolition of the 5-span concrete arch viaduct with traffic stoppage of 15 minutes or less

• The widening of ramps A, B and C to facilitate future re-decking of the bridges without interruption of traffic

• Redesign of the affected roadways

• Development, maintenance and protection of traffic plans

• Field Surveys

• Storm water management

• Erosion & sedimentation control measures

• Hydrology and hydraulic analyses (including determination of the impacts of the project on flood way elevations)

• Right-of-way plans

• Signing and lighting plans

• Coordination with Conrail, the PUC and all utilities
