SwiftGate for Pennsylvania Turnpike

摘要

The Tuscarora Mountain Tunnel consists of individual two-lane highway tunnels through the Tuscarora Mountain between Huntingdon and Franklin Counties in rural Pennsylvania. Each tunnel is around 1.6km long with portal buildings at each end. As part of a rehabilitation project, Versilis, based in Quebec, Canada, was selected by the Pennsylvania Turnpike Commission to supply a permanent automated lane closure system at each tunnel approach. Tunnel closure using standard maintenance of traffic procedures can take up to 45 minutes or 90 minutes to open and close. This reduces the night-time work window. The solution was to install two series of SwiftGate HSG-18CW automated gate systems - 38 gates in all - to facilitate the lane shifts required as part of tunnel closures.
