Milepost A59.20, Northeastern Extension, Lehigh County
Accelerated Bridge Construction (ABC)
Accelerated Bridge Construction (ABC)
The Pennsylvania Turnpike Commission (PTC) will complete construction this fall on a bridge-replacement project in Lehigh County in eastern Pennsylvania utilizing a modern process called Accelerated Bridge Construction (ABC). This technique is being used to construct the Huckleberry Road Bridge (NB-363 Bridge) on Interstate 476 in South Whitehall Township.
Interstate 476 is a major urban interstate carrying an average daily traffic (ADT) of 31,174 vehicles per day (2019 pre-pandemic data).
This will be the fifth ABC project to be completed by the PTC. Instead of one to two years of Turnpike roadway lane closures and delays, most impacts will occur over the course of a single weekend with this ABC method. The final stage of the bridge replacement work is a weekend closure of I-476 that is scheduled to start on Friday, Oct. 14, and be completed by Monday, Oct. 17.
To prepare for the bridge replacement, the PTC has already closed Huckleberry Road in South Whitehall Township, and it will remain closed until December 2022. During the Huckleberry Road closure, please expect higher traffic volumes on detour roads. Motorists are encouraged to plan travel accordingly. Changeable message signs will also provide information on closures and detours. Work schedules are subject to change based on weather conditions.
The Huckleberry Road Bridge Replacement Project is part of the continuing improvements scheduled for the Pennsylvania Turnpike's Northeastern Extension (I-476).
This project includes the complete replacement of the Huckleberry Road Bridge (NB-363), milepost A59.20, in Lehigh County, PA.

If you have questions or comments about the Northeastern Extension, Lehigh County bridge construction, please contact:
The existing bridge is being replaced because it is nearing the end of its design service life and is considered functionally obsolete due to the lack of roadway shoulders. The replacement of this structure will accommodate the vehicular needs of motorists such as the public and emergency services and allow for safer and more effective travel in the area.
Construction of the bridge is ongoing and is anticipated to be completed in Fall 2022.
To minimize traffic disruptions during the weekend closure scheduled for Oct. 14 through Oct. 17, motorists are encouraged to avoid driving in the area, if possible. Advance notice of detours near and around the project area will be set-up and can also be accessed via the Turnpike Commission’s website here. If avoiding the area is not possible, motorists should anticipate the potential for heavier traffic volumes than normal along the Northeast Extension during the weekend closure and are advised to plan accordingly.
In an effort to complete the bridge replacement as quickly as possible, work will continue through the night over the course of the weekend closure, scheduled for Oct. 14 through Oct. 17. Full closure of the northbound and southbound directions of I-476 will occur from 9 p.m. Friday until 4 a.m. Monday.
The contractor will install 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 due to the adjacent stocked and wild trout streams.
The Turnpike Commission works continuously with local, state, and federal regulatory agencies such as the County Conservation Districts, 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 all projects are completed with the least impact to the existing environment.
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.
