I-70 Hanging Lake Tunnel Traffic Surveillance & Control System

Owner:
Colorado DOT

Location:
Glenwood Canyon, CO
Project Description:
Interstate 70 through Colorado’s Glenwood Canyon traverses a stretch of the Colorado River using unique construction techniques to minimize environmental impacts to the scenic beauty of the region. An Advanced Traffic and Facilities Management System (ATFMS) was developed and installed by Transdyn in two tunnels and four miles of I-70 through the Canyon. This system monitors vehicle speed, vehicle length and height, traffic congestion and incidents, traffic lane devices, variable message signs, tunnel ventilation system, and electrical distribution.
