Travel Advisory

Traffic Pace May 31 on Northbound NE Extension between MP A85 and A88 in Carbon County

May 26, 2022 – The Pennsylvania Turnpike Commission advises motorists that a traffic pace is scheduled on Tuesday, May 31, at 11:30 PM in the northbound direction of the Northeast Extension (I-476) between mileposts A85 and A88.

During the traffic pace, the northbound left lane of the Northeast Extension will be shifted onto the rebuilt median to set up a long-term traffic pattern that will be used during the first phase of construction of the Turnpike’s $88 million project to replace the Hawk Falls Bridge in Carbon County.

Motorists should use caution and be prepared for slow or stopped traffic approaching these areas. All work is weather permitting.

This project will replace the 738-foot-long Hawk Falls Bridge that carries two lanes of Turnpike traffic in each direction over Mud Run in Penn Forest Township and Kidder Township, Carbon County. The 111-foot-long Hickory Run Road Bridge that carries Turnpike traffic over PA State Route 534 also will be replaced under this contract.

Digital message signs will also provide information on closures and detours. Motorists are encouraged to plan travel accordingly. Work schedules are subject to change based on weather conditions. The scheduled activities will be pushed back to the following day/evening in the event of any cancellations.

Project Overview

Read the May 25 Construction Update

The Hawk Falls Bridge Replacement Project is part of the continuing improvements scheduled for the Pennsylvania Turnpike's Northeast Extension (I-476).

Project Summary

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.
