In recent years, Sargent Electric Company has worked with local contractors and Pennsylvania Department of Transportation to perform various upgrades and modifications to the Liberty Tunnel.
Sargent Electric Company removed, modified, and re-installed the entire lighting system in both tunnels, approximately 1,600 luminaries. Our team also installed new communication systems located at the North and South Portal buildings. Approximately 7,000’ of new 48F fiber optic cable was installed and integrated into the existing traffic control systems at each tunnel end, including fusion splicing and OTDR testing of all fibers. Numerous supporting electric activities were performed within each tunnel.
