Pecos Street over I-70 Bridge Replacement
- Jan 22, 2015
The Colorado Department of Transportation chose to use accelerated bridge construction (ABC) techniques during replacement of the Pecos Street Bridge to minimize impact to the traveling public. After construction, the bridge was rolled about 1000 ft to its final location using self-propelled modular transporters (SPMT). Using this method, the disruption was minimized as the entire bridge move was conducted during a 50-hour closure of I-70. This time also included demolition of the existing structure. The entire superstructure was constructed using cast-in-place concrete construction along with epoxy-coated reinforcing steel.
More than 1,000 people visited the public-viewing area to observe moving of the 2,400-ton bridge.
