| Project Profile: Tuscarora Tunnel on the Pennsylvania Turnpike Project: Mountain Tunnel Lighting and Touch Screen Control System Client: Pennsylvania Turnpike Commission Construction Cost: $7 Million Tunnel Renovation Scope of Work: PSE completed a project for the design of a new mountain tunnel lighting system and computer control system as part of a $7 million tunnel renovation project for the Pennsylvania Turnpike Commission (Commission). The Illuminating Engineering Society of North America (IESNA) recognized PSE with an award for design excellence. Key benefits of the new lighting and control systems are reduced maintenance, lower operating costs, and improved driver safety. The 30-year-old fluorescent lighting system, once considered state-of-the-art, had become obsolete and costly to maintain. 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 United States renovated to meet the most stringent tunnel lighting standards, specifically, the IESNA/ANSI RP-22-96 "Recommended Practice for Tunnel Lighting." |

| All tunnel systems operate through a sophisticated touch screen control system. The person manning the tunnel can control tunnel systems simply by touching their finger on the computer monitor. The new system reduces maintenance. Longer life lamps are used and the luminaires are spray washable. The system uses high-tech, low-smoke, halogen-free, polymeric cables on non-corrosive cable tray for power feeds. Sidewall-mounted luminaires accommodate existing tunnel design, and provide clearance for trucks in the tunnel. PSE met all the design criteria for the replacement system including: |
