Project Overview
From early May through August 2018, crews on this project removed lighting at the US Highway 550 Red Mountain Pass Tunnel Shed and replaced it with more energy-efficient LED lighting.
The project on US Highway 550 between Silverton and Ouray, approximately eight miles north of the Red Mountain Pass summit cost $675,000 and was completed on schedule.
Work Completed
Crews completed the following:
- removed the existing lighting and electrical circuit;
- replaced 198 interior lights;
- replaced all the associated electrical wiring with new electrical system;
- installed 11 contactors and a new program logic controller (PLC).
The PLC operates by a photocell and will allow different light settings for daytime and nighttime. The old, out-of-date lighting system was updated with new LED, energy-efficient lighting. The updated lighting will use less power, while allowing more light, for better travel visibility at all times while driving through the tunnel.
