The Hawk Falls Bridge Replacement Project is part of the continuing improvements scheduled for the Pennsylvania Turnpike's Northeast Extension (I-476).
This project includes the complete replacement of the Hawk Falls Bridge (NB-610), milepost A-88.59, and the nearby Hickory Run Road Bridge in Carbon County, PA.
Construction Start: Fall 2021
Construction Completion: Spring 2025
Project Total: $88 million
General Contractor: Trumbull Corporation
Construction Manager: STV, Inc.
Design Consultant: Modjeski and Masters, Inc.
The existing Hawk Falls Bridge (Bridge NB-610) is a 738'-long, three-span deck truss bridge with deck I beam approach spans. It carries two lanes of Turnpike traffic in each direction over Mud Run in Penn Forest Township and Kidder Township, Carbon County. The existing bridge is scheduled for replacement because it is nearing the end of its design service life and considered functionally obsolete due to lack of roadway shoulders.
The replacement Hawk Falls Bridge will be a 720'-long steel structure featuring a 480' deck arch span flanked by four 60' deck plate girder spans. As with the current bridge, the new bridge will carry two traffic lanes in each direction, but it will also provide 12' wide outside shoulders and 6' wide median shoulders. Three welded, steel box arch ribs will be utilized to create an aesthetically pleasing structure that spans the deep Mud Run Valley located within Hickory Run State Park.
The Hickory Run Road Bridge, located directly to the north of the Hawk Falls Bridge, will also be replaced with this project. This three-span overpass bridge, measuring 111' in length, carries the PA Turnpike over PA State Route 534. It will be replaced with a new 120' long, single-span bridge. By eliminating the two existing concrete piers, the new bridge will provide a more open feel for travelers on Hickory Run Road, and also provides room for future roadway upgrades on this vital link through Hickory Run State Park.
To maintain smooth and consistent traffic flow on the Turnpike during construction, both new bridges will be constructed on a new roadway alignment just east of the current alignment. Once completed, traffic will be shifted to the new structures with only minor traffic control measures needed to complete the transitional roadway.
The existing bridges are being replaced because they are nearing the end of their design service life and considered functionally obsolete due to lack of roadway shoulders.
Construction on the larger arch bridge begins in spring 2022 and is anticipated to be completed in mid-2024. Construction of the Route 534 overpass will also begin in spring 2022 and be completed in stages by mid-2025.
To minimize traffic disruptions, the Hawk Falls and Route 534 bridges are being constructed on new roadway alignment to the east of the existing bridges. While everything will be done to minimize traffic disruptions, lane restrictions will be in place periodically during construction.
Most of the construction will take place weekdays during normal construction worker hours. However, the contractor always has the option to work at night or over weekends if necessary to meet completion milestones.
The contractor will install the project's environmental controls. They include erosion and sedimentation controls to slow and filter the natural stormwater runoff during construction prior to its entering natural lands or the surrounding waterways, which protects aquatic life. Special restrictions have been placed on construction in the adjacent stocked and wild trout streams.
The Turnpike Commission works continuously with local, state, and federal regulatory agencies such as the Carbon County Conservation Office, the Department of Conservation and Natural Resources, the Pennsylvania Department of Environmental Protection, the Pennsylvania Fish and Boat Commission, the US Army Corps of Engineers, and local special interest groups to make sure the project is completed with the least impact to the existing environment. The project also employs an Environmental Monitor to ensure that environmental controls remain in place and functioning properly.
This project is fully funded entirely by the Pennsylvania Turnpike Commission, with no federal or state tax dollars involved.
No. The Turnpike does not raise tolls to fund individual projects.
