From  Route 885 intersection to approximately 200' after the New Jersey Avenue intersection the existing concrete pavement will be reconstructed. The remainder of Route 837 will be mill and resurfacing of the existing asphalt pavement. The construction on Route 885 will consist of concrete reconstruction.  

There will be approximately 11 small strip takes along the frontages of parcels to replace existing guiderail and signal pole that are currently outside of existing Right-of-Way. 

Environmental

Within the project limits there is Clairton Park and Dravosburg Ballfields but will not be affected by the project. Access to these facilities will be maintained at all times during construction. 

Traffic during construction is anticipated to utilize a combination of short-term and long-term flagging operations on Route 837. To complete the concrete reconstruction of Route 885 there will be truck detours and phased short car detours utilizing municipality roads. The northbound truck detour will be approximately 14.6 miles in length and the southbound truck detour will be approximately 4.6 miles in length.
