BRIDGE CONSTRUCTION: First prefabricated bridge in Arizona to go up on Route 66

The Arizona Department of Transportation (ADOT) will be installing the state’s first prefabricated bridge along Oatman Highway, or old Route 66, in Mohave County. The 110-ft bridge is being manufactured in Phoenix and then will be transported in sections to the site in northwestern Arizona. When completed, the bridge will carry traffic over the Sacramento Wash, about a mile north of I-40 near Topock.

American Society of Civil Engineers’ 2017 Infrastructure Report Card

The ASCE’s 2017 Infrastructure Report Card continues to give bridges a grade of C+ (“mediocre, requires attention”). “The U.S. has 614,387 bridges, almost four in 10 of which are 50 years or older. 56,007 — 9.1% — of the nation’s bridges were structurally deficient in 2016, and on average there were 188 million trips across a structurally deficient bridge each day. While the number of bridges that are in such poor condition as to be considered structurally deficient is decreasing, the average age of America’s bridges keeps going up and many of the nation’s bridges are approaching the end of their design life. The most recent estimate puts the nation’s backlog of bridge rehabilitation needs at $123 billion.”
