PTC MP 242 to 245 Roadway and Bridge Reconstruction
- Project Name: PTC MP 242 to 245 Roadway and Bridge Reconstruction
- Project Client: Pennsylvania Turnpike Commission
- Project Location: Fairview Township, York County, Pennsylvania
The Pennsylvania Turnpike Commission completed a total roadway reconstruction and widening of three miles of the Pennsylvania Turnpike between the Harrisburg West Interchange and Susquehanna River Bridge. Construction management services provided by A.D. Marble included the construction and post-construction monitoring of a 1.45-acre wetland mitigation site and 2,596 linear feet of off-site stream mitigation. Services also included evaluating construction noise, reviewing Notices of Violations (NOVs) for erosion and sediment control (E&SC) and providing recommendations, inspecting failed E&SC measures and recommending changes, performing an agency walkthrough to inspect E&SC measures, comparing wetland and stream impacts vs. permitted impacts to ensure compliance, providing additional wetland delineations, providing recommendations for stream mitigation changes where field conditions did not match design conditions, and conducting an inspection of a wetland stormwater management basin.
In addition, A.D. Marble converted a standard erosion sediment control basin into a constructed stormwater wetland. This was due to the large overland flow runoff and to meet additional National Pollutant Discharge Elimination System (NPDES) requirements requested by the Pennsylvania Department of Environmental Protection (PADEP).
