Firm Engaged for Design of the New Pecos River Bridge

Modjeski and Masters was contracted by the Texas and New Orleans Railroad Company to prepare a study, recommendations, and final plans for a new Pecos River High Bridge to replace the existing structure (shown in this photo). Since World War II was in full swing, steel was considered very critical to the war effort, so the design had to utilize the material as efficiently as possible to safely span the Pecos River Canyon.
