Over the past five years, the Arizona Department of Transportation (ADOT) invested $275.2 million in pavement projects, bridge improvements, and other safety-related projects along the 360-mile Interstate 40.
“We know the value I-40 brings to Arizona as well as the rest of the country, and making sure this vital roadway continues to be safe for all motorists is our first priority,” Dallas Hammit, ADOT deputy director for transportation, said. “That’s why we continually invest in extending the life of bridges along the corridor and replacing pavement that gets damaged over years of heavy traffic use and winter weather exposure.”
Work since 2016 includes:
Approximately 90 miles of roadway have been replaced. This includes 35 bridges and five miles in each direction near Williams. Most of these areas are in higher elevations.
Several bridges have either been replaced or upgraded. The Fourth Street bridge in Flagstaff and the Bellemont bridges west of Flagstaff were replaced by “sliding” a new bridge into place using hydraulic jacks. The bridges on I-40 at Meteor City Road were rebuilt by creating new abutments integrating into the roadway with a reinforced soil foundation.
Several rest areas were improved, with truck parking permanently expanded by nearly 100 spaces.
