East-West Tunnel Lighting Survey

PSE provided a complete study of the existing lighting systems for the Tuscarora, Blue, and Kittatinny Tunnels. PSE evaluated existing electrical distribution and lighting systems and made recommendations for upgrades. The latest IES tunnel lighting standards using precision computer programs formed the basis for recommendations. PSE also made recommendations for lamping, maintenance, emergency distribution, luminaire replacement, and automated control system.

(PTC) New Tunnel Lighting System
for Tuscarora Tunnels

PSE designed a new system for the two-tube, one-mile tunnel to replace the fluorescent luminaires, switching, generators, and switchgear. It is comprised of almost 2,000 specially built high-efficiency, high-pressure sodium luminaires. Tuscarora is now the longest tunnel in the US renovated to meet the most stringent tunnel lighting standards, the IESNA/ANSI RP-22-96 "Recommended Practice for Tunnel Lighting." The Illuminating Engineering Society of North America (IESNA) recognized PSE with an award for its design.
