The West Juniata Parkway bridge, which spans Wild Cat Run in Greenwood Township, Perry County, reopened to traffic today. The West Juniata Parkway is officially designated as State Route 1015. This bridge was replaced as part of the Pennsylvania Department of Transportation's (PennDOT) Rapid Bridge Replacement Project and allows PennDOT to remove it from the state's structurally deficient list.
With the bridge reopened to traffic, motorists may notice a slight bump as they drive across the bridge until a polyester polymer concrete (PPC) overlay is applied to the deck. This is often the final step in completing box beam bridge projects. The PPC overlay is designed to protect the deck from the wear and tear brought about by Pennsylvania’s harsh winters and reduce the long-term maintenance costs.
The polyester material can only be applied when temperatures are consistently above 40 degrees, dry weather is forecasted and after the bridge concrete has cured for at least 30 days. Flaggers will assist in guiding alternating bi-directional traffic when the PPC overlay is applied in the spring of 2017.
This bridge is one of 558 bridges being replaced statewide under the Rapid Bridge Replacement Project. The Rapid Bridge Replacement Project is a public-private partnership (P3) between PennDOT and Plenary Walsh Keystone Partners (PWKP), under which PWKP will finance, design, replace and maintain the bridges for 25 years. The P3 approach allows PennDOT to replace the bridges more quickly while achieving significant financial savings and minimizing impact on motorists.
