More than 94 percent of Colorado’s major vehicle bridges are considered Not Structurally Deficient.
Structurally Deficient bridges do not meet minimum standards for condition or load-bearing capacity. They also often have one or more damaged or deteriorated structural members, such as a girder, truss or deck.
The condition of Colorado’s bridges is among the best in the nation. This is because a portion of your motor vehicle registration fee goes toward keeping Colorado’s bridges safe.
Additionally, CDOT formed the Colorado Bridge Enterprise (CBE) in 2009 to finance the repair, reconstruction and replacement of bridges in poor condition. At the end of 2013, 68 bridges had been repaired or replaced with FASTER funds. In addition, 10 bridges funded by FASTER were in construction; four bridge designs were completed; 26 bridges were in the design stage; and 22 bridge projects were waiting to be scheduled. A list of current FASTER bridge projects and a map of their locations is at www.coloradodot.info/programs/BridgeEnterprise.

The tunnel maintenance program tracks CDOT progress in maintaining tunnels on the State Highway System. A letter grade is given every year on maintenance activities at the Eisenhower-Johnson and Hanging Lake tunnels on I-70. Maintenance on these aging tunnels includes tunnel washing and sweeping, ventilation maintenance, snow removal, emergency response and round-the-clock television surveillance.
Although CDOT’s tunnel infrastructure is aging, in the 40 years the Eisenhower-Johnson Memorial Tunnel has been in operation there have been no traffic fatalities. More than 30 million vehicles have traveled the tunnel since it opened on March 8, 1973.
