The Pennsylvania Turnpike Commission retained Erdman Anthony for construction management and construction inspection services for the total reconstruction of the turnpike between mileposts 242 and 245 in York County, PA.
Our firm’s scope included the construction management and inspection of four projects.
The first two projects were “early action” replacements of two overpass bridges: Marsh Run Road and Old York Road. To accommodate the ultimate 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/enhancement. The bulk of this project was graded/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 will 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 italso involded 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:
- Sound walls/retaining walls
- Roadway reconstruction
- Construction of/extension of box culverts
- Southern widening of the Lewisberry Road bridge
- Stormwater best-management practices
Stages two through four reconstructed the center portion of roadway, and stages five and six reconstructed a portion of Lewisberry Road.
The project was completed in May 2018.
