Alcon Construction, Inc. has been building bridges for the past thirty-five years. In the 1990’s Alcon participated statewide in a bridge replacement program replacing on average three county bridges per year.  These bridges were located mostly in the San Luis Valley including Alamosa County, Rio Grande County, Conejos County, Costilla County, Saguache County and Mineral County.  Alcon also replaced one bridge in Jackson County.  Projects ranged from $57,000.00 to $150,000.00 in cost, roughly averaging one hundred thousand dollars per project.

In addition, Alcon has completed smaller bridge projects for individuals and larger projects such as the Alamosa walk bridge (picture located on the City of Alamosa website) and a box culvert on Highway 285 for the Colorado Department of Transportation. The latter project was just under a million dollars. The most recent bridge projects Alcon Construction, Inc. has built include the Vega bridge in Costilla County and Coller Bridge in Mineral County.

Alcon has poured second story concrete deck floors (Adams State University and Trinidad State Junior College are a couple examples) very similar to bridge decking work.

Alcon also completes multiple types of bridge rehabilitation and component construction. Alcon has built headgates, headwalls, inlet structures, outflow structures, metal trestle x-brace tensioning adjustments and constructed abutments. Some locations for this type of work have been the Chicago Ditch in East Alamosa, Trinchera Irrigation just outside Blanca, Sanchez Reservoir & Canal, South Fork Bridge, Hermit Lakes between Creede and Lake City, Ute Creek, the Cumbres & Toltec sites of Chama Bridge (abutment) and Lobato Trestle.
