Pecos Street over I-70 Bridge Replacement

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 selfpropelled 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-inplace concrete construction and epoxy-coated reinforcing steel (ECR rebar) was used to provide corrosion protection to the reinforcing steel.
