Project Profile

By EnCon Marketing Staff

Colorado Department of Transportation’s (CDOT) flyover ramp was installed at Santa Fe Drive and C-470 to reduce congestion on Santa Fe Drive and ease southbound traffic merging onto eastbound C-470.  The completion of this $23.3 million project was supported by EnCon Colorado through the supply of the bridge’s main structural elements.

EnCon Colorado produced the 1,713 ft. structure using 36 curved tub sections and straight trapezoidal Ugirders supported by precast pier caps, and precast/prestressed deck panels.  Over 200 deck panels were cast directly on top of the U girders in the plant after casting in order to create a torsionally rigid section.  The precast pieces have a radius size of 822’ feet.

The bridge was opened four months ahead of schedule and under budget, primarily due to the use of the precast prestressed concrete structural system.  Erection on the project was done at night in order to minimize disruption to the public.  This project was funded with money from Stimulus, CDOT, and Douglas County.  EnCon Colorado received the Award of Excellence for Bridge Construction in the 44th Annual Rocky Mountain Chapter American Concrete Institute (ACI) Awards competition.
