The Pennsylvania Turnpike Commission is taking a new look at a long-dormant plan to replace mile-long tunnels near Somerset.
The Pittsburgh Post-Gazette reported Wednesday the turnpike commission is considering six options to replace the Allegheny Tunnels.
Three of the options would require new tunnels, and the others would build an open highway either north or south of the existing route.

Depending on which approach the commission takes, the project would cost between $242 million and $694 million.
Proposals to replace the tunnels have been around for nearly two decades. Officials say replacement is needed because of the tunnels' age, traffic congestion and crashes.
A spokesman says turnpike commissioners could make a decision as early as this spring. Planning and construction could take six or seven years.
