Construction to be complete after Overlay Surface is applied to Bridge Deck
GREENWOOD TOWNSHIP – A Route 219 (Mahaffey Grampian Highway) bridge, spanning Curry Run in Greenwood Township, Clearfield County, reopened to traffic on Friday, Dec. 2.
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, 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 mid-2017.
This bridge is referred to as JV-38 and is one of 558 bridges being replaced under the Rapid Bridge Replacement Project.
JV references the joint-venture partnership between Walsh/Granite, which is leading construction for the entire project. Replacement work for this bridge was performed by Walsh Construction II.
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 will allow PennDOT to replace the bridges more quickly while achieving significant savings and minimizing impact on motorists.
