Proposed Needs

Highway Safety

Ramp curve issues, confusing lane assignments and ramp orientations / configurations, the inadequate bottleneck configuration at I-83 (Exit 70) with unsafe lane drops and merges, and high congestion along the freeway result in highway safety implications


The existing mainline I-81 routinely experiences relatively high speeds in excess of the posted speed limit and travel delay at several sections of roadway which contribute to operational and safety issues.

Land Use and Access

Commercial development will continue to increase between and south of I-81 Exits 67 and 69, increasing traffic volumes at both interchanges. Both exits provide access into the City of Harrisburg and surrounding communities.

Highway Infrastructure

The existing structures within the I-81 corridor were constructed in the 1960s and 1970s and are approaching the end of their serviceable life span.  The existing pavement was reconstructed in the 1990s and 2000s and ride quality is beginning to degrade. Gaps in ITS devices (CCTV) were identified in three locations (mile markers 69 SB, 69 and 71 SB).
