Built in 1939, the Allegheny Mountain Tunnel is a vehicular tunnel carrying the Pennsylvania Turnpike (Interstates 70 & 76) through the Allegheny Mountains east of the Somerset Interchange.

Throughout the 2000s, state officials attempted to implement plans to replace the tunnel, citing the westbound tube's age. In 2020, following analysis of several design alternatives, the Pennsylvania Turnpike Commission opted for a new road only alignment to the south of the tunnels, which – at $332 million for the versus $628 million for a replacement tunnel – is the least expensive and environmentally disruptive of the alternatives. As part of the project, several sharp curves to the east of the tunnel will be redesigned to meet current standards. The project is funded for design, but not for construction.
