US 54 Canadian River Bridge

SEGMENTS, SPRING 2016, VOL. 60

The New Mexico Department of Transportation (NMDOT) is replacing the existing US 54 steel deck truss bridge over the Canadian River south of Logan, New Mexico. The US 54 corridor is a main trucking corridor from Chicago to El Paso with over 50% truck traffic. US 54 also provides access to Ute Lake State Park, the second largest lake in New Mexico, which is popular with water and fishing enthusiasts. An alignment study and preliminary engineering for the new crossing was started in 2011 with public input reviewing eight different alignments and six structure types. The preferred alternative selected is a new offset eastern alignment of US 54 with a new three-span, cast-in-place segmental bridge, built in balanced-cantilever with form travelers.

A cast-in-place segmental structure type was selected to minimize impacts to the Canadian River and wetlands, with a long span design that can be constructed primarily from above with limited access in the deep ravine. The bridge will measure 43'-0" in width, with a span configuration of 200' -325'-210' along a constant horizontal curve. The box girder depth varies from 18'-0" at the piers to 8'-0" at mid-span and abutments. The new bridge will be New Mexico’s first cast-in-place segmental bridge and first segmental construction since the Big I Project (I-25 and I-40 Interchange) in Albuquerque.

The project is programmed for construction in 2017 and 2018. The bridge is currently in final design and scheduled for advertisement in early 2017. A pre-bid meeting for those interested in the project will be held in late 2016.
