The HATS region has nearly 5,000 miles of roadway with nearly 1,700 miles on the Federal Aid System:
Reported in inches per mile, International Roughness Index (IRI) ratings provide a metric which illustrats the smoothness of the ride on a surveyed stretch of road. While IRI provides a rating for the road, the evaluation of that rating varies depending on characteristics of the road itself. IRI evaluation and overall rating of a road depends on which business plan network it falls in. PennDOT’s breakdown of IRI evaluation is shown in the following graphic:
Broadly, the median IRI ratings for all business plan networks in the Federal Aid System fall within “Good” or “Excellent” ranges. Non-NHS roadways with less than 2000 ADT have seen overall improvement. In 2014, the median IRI rating in this business plan network fell into the “Fair” range. At the time of the writing of this plan, it has improved to the “Good” range.
Looking at the overall comparison of pavement quality in the HATS region, there has been improvement. Fair and poor segment miles have seen a slight decrease while Excellent and Good segment miles have seen an increase. Between 2014 and 2018, there has been an improvement of approximately 35 “Excellent” segment miles on Federal Aid roadways in the region while “Poor” segment miles have seen a decrease of the same amount, most likely due to recent resurfacing projects.
In terms of bridges, the region continues to be in good standing in regards to District targets in all areas except for structurally deficient (SD) deck area on the NHS Non-Interstate network (BPN2) and on the local network. HATS will move forward with a focus on bridges in these particular networks and continue to find resources to address bridge needs.
In 2017, Dauphin County received a $2 million grant to implement the $5 registration fee to address county bridges. Cumberland County also recently received state funding to complete one of their local bridges through PennDOT’s LaSeR initiative.
- Continue coordination with PennDOT to select projects for future TIP updates to address eligible SD or FO bridges or poor IRI roadway miles;
- Continue to assist municipalities in finding financial means to address local bridge projects;
- When released, coordinate with the necessary agencies to work toward applicable performance targets for pavement and bridges.
