Proposed Needs

Highway Safety

Short acceleration lanes with inadequate merging distance, poor sight distance, and high traffic congestion particularly during the morning rush hour result in highway safety implications.


The existing mainline I-81 routinely experiences relatively high speeds, greatly in excess of the posted speed limit and substantial travel delay in the northbound direction at Exit 65 and in the southbound direction at Exit 66, which contribute to operational and safety issues.

Land Use and Access

New residential and commercial development is anticipated near Exit 65 which will increase traffic volumes near the interchange. While no future development was reported near Exit 66, the municipality’s recent comprehensive plan update and corresponding land development ordinance updates will likely stimulate redevelopment opportunities north of Exit 66.

Highway Infrastructure

The existing structures on existing I-81 corridor were constructed in the 1970s and are approaching the end of their serviceable life span.  The existing pavement was either constructed in the 1960s or reconstructed in the 2000s and ride quality is beginning to degrade. A gap in ITS devices (CCTV) was identified near mile marker 66.
