I-40

FLAGSTAFF – Drivers along Interstate 40 through Flagstaff should be aware of around-the-clock lane restrictions while the Arizona Department of Transportation continues projects to improve the much-traveled highway.

Crews continue to work on replacing pavement on 10 miles of I-40 from the I-17 interchange east to Walnut Canyon Road. Eastbound I-40 is currently narrowed to one lane between I-17 and Butler Avenue through the evening of Friday, July 16.

Next week, eastbound I-40 will be narrowed to one lane between Butler Avenue and Country Club Drive. 

Let us just take a moment to say how much we love I-40. How much, you might ask? Oh, we love it to the tune of $275 million.

PHOENIX – Recognizing the importance of Interstate 40 for commercial trucks and travelers, the Arizona Department of Transportation has invested $275.2 million in bridge improvements, pavement projects and other safety-related projects along the 360-mile corridor over the past five years.

Since 2016, ADOT has replaced pavement on about 90 miles of I-40, which includes rebuilding 5 miles of the interstate in each direction near Williams, and repaired, upgraded or replaced 35 bridges along the corridor.

PHOENIX – The Arizona Department of Transportation is starting a project to repave a 10-mile stretch of Interstate 40 between I-17 and Walnut Canyon Road in Flagstaff. This project will improve safety and extend the life of the highway.

The work will include replacing the existing pavement in both directions of I-40 and replacing pavement on the on- and off-ramps at four intersections in the project area. Work will also include making repairs to bridge decks along the 10-mile stretch and repairing guardrail as needed.

PHOENIX – With warmer weather coming to Arizona’s high country, the Arizona Department of Transportation is ramping up construction projects to improve safety and extend the life of the infrastructure.

In the Flagstaff area, ADOT has already started projects to replace the Interstate 40 bridges over Business 40 which connects to Historic Route 66 in west Flagstaff. The project, which is approximately 3 miles west of the junction with Interstate 17, will replace the east- and westbound bridges on I-40 in their entirety. The project is anticipated to be completed by fall of 2022.

Does merging present a dilemma for you? Then let us introduce the zipper merge to help!

PHOENIX – The Arizona Department of Transportation is starting a project to replace the Interstate 40 bridges over Business 40, which connects the interstate to Historic Route 66 in west Flagstaff. 

As we build new bridges along I-40 at Two Guns, we are connecting more than two pieces of roadway.

PHOENIX – In order to increase safety and mobility in highway work zones, the Arizona Department of Transportation is studying a “smart work zone” at an existing I-40 bridge project located between Flagstaff and Winslow.

A smart work zone is a traffic management system that can be controlled remotely through computer networks, portable message boards and sensor technology to provide motorists with real-time traffic information as they approach construction work zones. This project utilizes a dynamic merge system, which is a specific type of smart work zone.

The community of Ash Fork has always had a knack for being at the right place when it comes to popular transportation.

PHOENIX – The Meteor Crater Rest Area on Interstate 40 between Flagstaff and Winslow in northern Arizona has closed for a nearly $3.5 million renovation project that’s expected to be completed by the fall.

While closed to the traveling public, the rest area will remain open for commercial truck parking only. Message signs placed on I-40 in each direction approaching the rest area will advise drivers of this.

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.
