Long-term plans call for major maintenance to be performed on the twin Allegheny Mountain Tunnels; however, this presents a major problem for traffic. On October 22, 2013, the PTC announced plans to replace the tunnels, the older of which was 73 years old that year, with either new tunnel or a bypass due to the age and condition of the twin tunnels and the need for additional capacity. Approximately 11 million vehicles drive through the tunnel every year.
