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. The new structure is a three-span, cast-in-place segmental bridge, built in balanced-cantilever with form travelers.
The 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.
Hatcher Technical worked with construction engineer McNary Bergeron and the contractor to provide:
- Fully integrated shop drawings for the cast in place concrete superstructure, including pier tables, typical segments and cast-in-place end spans
