Construction Update

Excavation, Foundation Construction This Summer 

July 14, 2022 – Construction is well underway this summer on a project to replace two Pennsylvania Turnpike bridges on the Northeast Extension (Interstate 476) in the Pocono Mountains between the Lake Harmony/Jim Thorpe (Exit 87) and Pocono (Exit 95) interchanges in Carbon County.

Turnpike traffic is shifted slightly through the work zone for large-scale excavation that is underway for the new northbound and southbound Turnpike roadway that will connect to the new bridge.

Travelers are advised to reduce speed in the work zone as loaded dump trucks and other construction vehicles exit and enter the highway from the adjacent work area.

Construction of foundations for the new Turnpike bridge will begin this summer and continue through spring 2023.

Local motorists on Route 534 may encounter occasional flagger-controlled stoppages for construction vehicles entering or leaving the construction access road there.

Located mostly within the boundaries of Hickory Run State Park, the $88 million, toll-funded project will replace the Turnpike’s Hawk Falls Bridge, named after one of the Park’s most popular attractions.

On a new alignment east of the existing bridge, the smaller adjacent bridge over Route 534 is also being replaced to accommodate the new alignment of the larger span.

Erection of the bridge’s 3,300 tons of structural steel that will rise some 200 feet over the Park’s Mud Run Valley is expected to begin in summer 2023. When completed in summer 2024, the bridge will match the elevation of the existing mainline roadway.

The new Hawk Falls Bridge will be 720 feet-long and incorporate a unique, eye-catching “skewback arch” design. It will be four lanes wide, with six-foot medians and 12-foot shoulders. It will replace the existing 738-foot-long truss bridge that is nearing the end of its design service life and considered functionally obsolete due to lack of shoulders.

The new bridge over Route 534 will be a single-span structure, also four lanes wide, with six-foot medians and 12-foot shoulders and will be built a half-at-a-time. The first half will be completed during the current construction phase.

At the end of Stage 1, Turnpike traffic will be traveling over the new Hawk Falls bridge.

The second stage of the project entails completing the remaining half of the Route 534 bridge and some connecting portions of the southbound roadway.

At the end of Stage 2, traffic will be traveling over the new Route 534 bridge

The final phase of the project will see the demolition of the existing Hawk Falls bridge, completing new paving in transition areas, and removal of the old roadway. A series of basins and rain gardens will be created in its place.

The Hawk Falls Bridge Replacement Project is part of the Turnpike's continuing improvements on the Northeast Extension and is solely toll-funded.

The Trumbull Corporation of Pittsburgh is the general contractor.
