Pennsylvania Turnpike Reconstruction Management

Join project manager Noel Caron, PE, for a recap.

The Pennsylvania Turnpike Commission contracted Erdman Anthony for construction management (CM) and construction inspection (CI) services for the total reconstruction of the turnpike between mileposts 242 and 245 in York County, Pennsylvania. Our firm provided CM and CI services for four projects that had various challenges, including the tight proximity of businesses and residents, unsuitable soil characteristics, and large cut slopes on the alignment’s south side.  

The first two projects were “early action” replacements of two overpass bridges: Marsh Run Road and Old York Road. To accommodate a six-lane configuration, both bridges were replaced in 2013 with two-span precast-concrete spread box-beam bridges. 

The third project included construction of approximately 2.5 acres of wetland mitigation and approximately 3,000 linear feet of stream relocation or enhancement. The bulk of the project was graded or mitigated in 2015; final planting occurred in 2016.

The total reconstruction – the fourth and largest of the projects – consisted of staged widening of the turnpike mainline (milepost 241.98 to milepost 245.51) from four lanes to six lanes with widened median and outside shoulders from the Harrisburg West Interchange to the Susquehanna River Bridge.

The total reconstruction also included reconstruction of SR 0114 (Lewisberry Road) and the relocation of T-970 (Evergreen Road). The mainline project included the replacement and/or widening of the mainline bridges and culverts [EB-207, MP 242.29, bridge replacement over SR 0114 (Lewisberry Road); EB-208, MP 242.35, culvert extension – unnamed tributary to Yellow Breeches Creek; EB-211, MP 244.54, culvert extension – unnamed tributary to Marsh Run] at various locations throughout the project limits, and it also involved various types of retaining walls and the extension of an existing noise wall.

During stage one, traffic was shifted into the median for the majority of the project area while most of the “outside” work was completed. This included:

    • Earthwork
    • Noise walls and retaining walls
    • Roadway reconstruction
    • Construction of or extension of box culverts
    • Southern widening of the Lewisberry Road bridge
    • Stormwater best-management practices
    • Drainage

Stages two through four reconstructed the center portion of roadway, and stages five and six reconstructed a portion of Lewisberry Road. 

This five-year reconstruction delivered various environmental benefits, including wetland mitigation, stream enhancement, and a reduction of vehicle emissions through on-site recycling of concrete slabs for subbase.

Sustainable Design Impact

Wetland mitigation and stream enhancement improved habitat in two of the Commonwealth’s watersheds, and reusing on-site roadbuilding material lowered emissions that delivery trucks would have produced.
