I-40

PHOENIX – While 2020 presented many challenges, the Arizona Department of Transportation continued to serve drivers in northern Arizona by using different methods, including the innovative bridge slide, to improve bridges to keep cross-country commerce flowing and increase the mobility of local traffic.

PHOENIX – The new Fourth Street bridge passing over Interstate 40 in Flagstaff is now complete, providing improved safety and traffic flow in the area.

Do you know you can find the spot on Interstate 40 that determines which way water will flow? Let us show you!

You may have seen a sign for this long-forgotten town while cruising down I-40, but did you know about its bizarre past?

PHOENIX – The Arizona Department of Transportation has been granted environmental approval to move forward with plans to improve the US 93/I-40 traffic interchange in west Kingman.

Our project on the Fourth Street bridge over Interstate 40 is one of those times when things just seem to slide into place.

PHOENIX – Using an innovative bridge slide technique that accomplishes in days what ordinarily would take months, construction crews have placed a new Fourth Street bridge over Interstate 40 in Flagstaff.

The new, wider bridge will improve traffic flow and have a dedicated path for bicycles and pedestrians connecting the Flagstaff Urban Trail System across the interstate.

PHOENIX – The Arizona Department of Transportation will use an innovative method to slide the new Fourth Street bridges over I-40 in Flagstaff into place later this month, cutting by months the time it would normally take to build a new bridge.

Installing the new bridges will require the closure of Fourth Street over Interstate 40 beginning at 8 p.m. Friday, July 17. The work will continue over the next couple of weeks and is scheduled to be completed early Monday, Aug. 3.

It may not quite be to the level of "Star Trek," but ADOT has embraced virtual communication during the current public health situation.

PHOENIX – The Arizona Department of Transportation has expanded a renovation project at the Interstate 40 Meteor Crater Rest Area in northern Arizona to nearly double the parking spaces available for commercial vehicles.

With 65 truck parking spaces currently available at the rest area between Flagstaff and Winslow, ADOT is adding 32 spaces to the westbound facility and 24 spaces to the eastbound facility. This $5.2 million improvement was added to a current project renovating both the Meteor Crater Rest Area and the Painted Cliffs Rest Area along I-40 near New Mexico.

Construction projects continue through the current public health situation, which means ADOT had to adapt in order to keep the public engaged.

PHOENIX – The Arizona Department of Transportation is seeking input on a project to build a freeway-to-freeway interchange between US 93 and Interstate 40 in west Kingman by hosting the agency’s first project-level virtual call-in public hearing.

PHOENIX – The Arizona Department of Transportation is starting a project to reconstruct the St. Anselm Road bridge over Interstate 40 at milepost 348 between US 191 and the New Mexico state line in the community of Houck.

The bridge, located on the Navajo Nation, will be closed for the duration of the project. Drivers should also expect overnight closures of I-40 during portions of  the project, with traffic using the on- and off-ramps at the St. Anselm Road interchange to exit and re-enter the freeway. 

PHOENIX – A project fast-tracked by the Arizona Department of Transportation will add 38 truck parking spaces to the Haviland Rest Area along I-40 west of Kingman.

Deemed an emergency project due to the current public health situation, the upgrade will allow more commercial drivers to rest as they travel long distances delivering essential supplies. The State Transportation Board awarded the $3.98 million project to Fann Contracting on Tuesday.

PHOENIX – In partnership with Flagstaff, the Arizona Department of Transportation is starting a project this week to improve traffic flow and add capacity for bicycles and pedestrians where Fourth Street passes over Interstate 40.

The Fourth Street bridge, which is currently one lane in each direction, will be replaced with a wider bridge offering two lanes in each direction, a center turn lane and a protected path for bicycles and pedestrians on one side and a sidewalk on the other. 

An ADOT employee went out of his way to help two out-of-state motorist with a flat tire on Interstate 40.

It's not a dance move, but an innovative new technique for replacing bridges. Read more in today's blog.

PHOENIX – A new technique that basically slides precast bridges into place has greatly reduced delays for the Bellemont community with an Arizona Department of Transportation project replacing spans over Interstate 40 at Transwestern Road west of Flagstaff.

Using this technique, which the contractor proposed, allowed crews to replace the bridges during a nine-day closure of Transwestern Road over I-40 rather than having the six to eight months of restrictions required for a traditional bridge replacement project.

PHOENIX – As progress continues on the Bellemont traffic interchange along Interstate 40 west of Flagstaff, the Arizona Department of Transportation will close the highway under the bridge overnight on Monday, Sept. 16, and Thursday, Sept. 19.

Eastbound I-40 will close under the overpass for the Bellemont/Transwestern Road interchange from 7 p.m. to midnight on Sept. 16, and the westbound direction will close from 7 p.m. to midnight on Sept. 19.

Not one, but two, innovative techniques are helping us save time and money as we rebuild the bridges on Interstate 40 at Meteor City.
