Description: NM 50 over Glorieta Creek is a small, unique bridge in an environmentally and historically sensitive area. The bridge is within the Pecos National Historical Park where the Battle of Glorieta Pass occurred during the Civil War. An adjacent historic well, witness trees, building, and stone wall are from the Civil War era and had to be protected during construction. A perennial stream flows beneath the bridge that feeds an adjacent wetland. The old 1923 bridge was cut apart from above and lifted out to protect the environmentally sensitive stream below, and the new 2021 bridge was built in very tight quarters within the narrow, existing right-of-way. Closure of the bridge during construction meant a 20-mile detour for those living east of the bridge who commute to Santa Fe.  As a result, construction was accelerated (7 weeks). Abutment caps, wingwalls, approach slabs, and prestressed slab beams were all precast. Ultra-high performance concrete (UHPC) connections were used throughout. Design and construction details, including lessons learned, are presented.
