It is within the boundaries of the Petrified Forest National Park. HistoryIn 1929 the Arizona Highway Department (AHD) began to renovate what was then U.S. Route 66. The project consisted of approximately {{convert|22.5|mi|km}} of grading and road surfacing, as well as the construction of several bridges. The Querino Canyon Bridge was the largest of these. In November, the contract for the bridge and roadways was awarded to F.D. Shufflebarger, a contractor from Phoenix, for a sum of $184,604. While they began work prior to year's end on the roadways, they did not begin work on the bridge until 1930, completing it by December of that year, which was behind schedule.[1] In the 1960s, this section of Route 66 was re-routed due to the construction of Interstate 40 (I-40), leaving this particular highway to a county road.[1] DescriptionThe length of the bridge's three spans is {{convert|77|ft|m}}, with a total length of {{convert|269|ft|m}} when the approaches are included. The bridge is {{convert|20|ft|m}} wide. The substructure consists of concrete abutments and pedestals, along with steel piers. Sitting on the steel piers are three Pratt deck trusses, supporting a concrete deck.[1] See also
