Geocal assisted the Colorado Department of Transportation (CDOT) in reconstructing the 2 ½ mile segment of Interstate 70 between Tower Road and Colfax Avenue (U.S. 40/287). Work for this project consisted of removing portions of the existing asphalt and replacing it with concrete pavement. Other areas of existing asphalt were overlaid with new concrete pavement, shoulders were widened, and new bridges were constructed over the Union Pacific Railroad and Smith Road. The project also included numerous retaining walls, drainage improvements and water quality ponds, guardrails, curbs and gutters, signing and striping.
The bridge demolition and reconstruction that was part of this project replaced a bridge that is at capacity. The new bridges included wider shoulder lanes that have improved safety for all motorists.
During this phase of construction, the on ramp from northbound Tower Road to eastbound I-70 was realigned to improve the flow of traffic and safety at this location. Phasing of this project has allowed traffic flow to continue in the area at reduced capacity without utilizing full long term complete road closures as originally designed. By removing and replacing the bridge in two segments, traffic flow continued on this stretch of road with lane reductions.
