This $110M project at the Tuscarora Tunnel will improve both the eastbound and westbound tunnel tubes. The tunnel is located on the PA Turnpike Mainline (I-76) between mileposts 186 and 187 between the Fort Littleton Interchange (Exit 180) and the Willow Hill Interchange (Exit 189) on the Huntingdon/Franklin County line. The project is needed to improve and modernize the tunnels and to maintain safety for workers and travelers.

Throughout the project, there will be multiple traffic patterns required to accommodate work tasks. Travelers can expect intermittent closures, crossover traffic patterns, and possible delays. At times, one tunnel tube may be closed completely while the other tube will have both lanes open with bi-directional traffic. All traffic in both directions will merge into one lane approaching the tunnel, with a reduced speed limit. Traffic patterns are subject to change according to the time of year, weather, and projected travel volumes.

The eastbound tunnel tube opened in 1940 and the westbound opened in 1968. The two tubes were last renovated in the 1980s. This project was issued Notice to Proceed on July 31, 2019 and has an estimated completion date of June 2023.
