PTC Total Reconstruction MP 199-213
As part of their on-going efforts to modernize and update their roadway infrastructure, the Pennsylvania Turnpike Commission identified the section of Mainline between Mileposts 199.30 and 213.83 for a total roadway reconstruction. This section lies within Franklin and Cumberland Counties in southcentral Pennsylvania and includes the Blue Mountain Interchange.
As a subconsultant to KCI Technologies, Inc., Gibson-Thomas provided:
- Stream surveys and hydrologic and hydraulic analyses for 25 structures
- Three stream relocation designs
- Drainage designs
- Stormwater management designs
- Erosion and sedimentation control plans
- PADEP Joint Permit and NPDEPS permit preparation for seven miles of the corridor
- Structural design for the extension or replacement of 20 reinforced concrete arch culverts and one slab bridge
- DARWin pavement design
- Utility coordination
As part of the reconstruction, the existing 10-foot median was reconstructed to 46 feet to incorporate a 3rd travel lane in each direction.
Construction of the last section within of this corridor was completed in 2019.
