I-83 Exit 4 Improvements (SR 0083 Section 074)

Project Description

Shrewsbury Township, York County, PA

PROJECT OWNER
Pennsylvania Department of Transportation, Engineering District 8-0

Interstate 83 Exit 4 is an existing diamond configuration interchange with signals located at the ramp intersections with PA 851.  Due to the growth of the Shrewsbury area, congestion is experienced at the interchange during peak periods, and traffic exiting I-83 northbound and southbound backs up onto I-83.  The existing bridge carrying I-83 over Route 851 is structurally deficient.  The project will replace the existing I-83 bridge with a two-span structure that will accommodate the additional lanes on PA 851 and possible future widening of I-83.  The project will also implement a Diverging Diamond Interchange (DDI) and lengthen the I-83 northbound and southbound on and off interchange ramps.
