Engineering Project Case Studies | Erdman Anthony

Construction Management and Construction Inspection

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

THE PROJECT
The Pennsylvania Turnpike Commission completed a total reconstruction of the turnpike between mileposts 242 and 245 in York County.

The four projects involved presented various challenges, including the tight proximity of businesses and residents, unsuitable soil characteristics, and large cut slopes on the alignment’s south side.  

Erdman Anthony was selected to provide construction management and construction inspection services for all four projects included in the reconstruction. 

FEATURES/SOLUTIONS
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 total reconstruction – the fourth and largest of the projects – consisted of staged widening of the turnpike mainline from four lanes to six lanes with widened median and outside shoulders from the Harrisburg West Interchange to the Susquehanna River Bridge. 

This total reconstruction also included:
•    Reconstruction of SR 0114 (Lewisberry Road) and the relocation of T-970 (Evergreen Road)
•    Replacement and/or widening of the mainline bridges and culverts 
•    Culvert extensions at various locations throughout the project limits
•    Various types of retaining walls and the extension of an existing noise wall

IMPACTS
During stage one of the reconstruction, traffic flow was maintained by shifting onto the median for the majority of the project area while most of the “outside” work was completed.

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.
