Capacity issues at signalized intersections, ramp curvature and atypical interchange layout at PA 581 (Exit 59) result in highway safety implications.
The existing mainline I-81 routinely experiences relatively high speeds in excess of the posted speed limit in the northbound direction between Exit 61 and Exit 65; and significant travel delay in the southbound directions, which contributes to operational and safety issues.
Land Use and Access
Commercial and residential development will continue to increase near Exits 57 and 61, resulting in traffic increases on area roads. The construction of a new hospital and expansion of an existing hospital at Exit 61 will also increase traffic volumes on roads in proximity to the interchange.
The existing pavement and structures within the I-81 corridor were constructed in the 1960s and 1970s and are approaching the end of their serviceable life span. Gaps in ITS devices (CCTV and DMS) and antiquated existing equipment were identified near mile marker 58 NB.
