The Pennsylvania Turnpike Commission has retained Erdman Anthony for construction project management and inspection services for the Mileposts 242-245 Total Reconstruction Project in York County, PA.
This agreement’s scope includes the construction management and inspection of four projects. The first two 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 construction projects, consists of staged widening of the turnpike mainline (milepost 241.98 to milepost 245.51) from four lanes to six, from the Harrisburg West Interchange to the Susquehanna River Bridge.
The project also includes reconstruction of SR 0114 (Lewisberry Road) and the relocation of T-970 (Evergreen Road). The mainline project will include 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 will also include various types of retaining walls and the extension of an existing noise wall. The expected completion date is 2018.
During stage one, the traffic was shifted into the median for the majority of the project area, and most of the “outside” work was completed. This work included the majority of the earthwork, all the sound walls/retaining walls, roadway reconstruction, construction of/extension of box culverts, southern widening of the Lewisberry Road bridge, stormwater management best management practices, drainage, and other incidental construction. The project is now in its second stage, with traffic shifted to the previously constructed outside lane and shoulder. Work is also progressing in the median.
