Bridges

PHOENIX – While work is underway to reconstruct Bridge No. 1 along Interstate 15, access to the Virgin River that passes under the bridge will be closed for public safety beginning March 8.

The Arizona Department of Transportation will be replacing the abutment foundations of the bridge as part of the project. With heavy equipment and work taking place beneath the bridge, the public will not be able to access or utilize the river or adjacent lands at this location during the construction project.

Have you thought about being an engineer when you grow up? At ADOT, we have many different types, all doing important work!

It's Engineers Week and ADOT Director John Halikowski is saying a big thank you for all that engineers do for the agency.

This bridge in Cochise County may not look like it has a lot to do with ADOT, but it's an example of a changing time in the world of infrastructure. 

How do you know that a slope is secure? Why, you use inclinometers and piezometers, of course!

PHOENIX – The Arizona Department of Transportation is set to begin work on replacing Virgin River Bridge No. 1 along Interstate 15 with a brand new bridge that will increase safety and help the corridor to continue carrying commerce for decades to come.

The Houghton Road interchange project at I-10 near Tucson has been in the works for awhile, but this photo will help you get a sense of the scope of the project.

James Lemmon's job at ADOT rocks. Literally, it's all about rocks.

If you drove on SR 77 near Winkelman this month, there was no missing this important sign of progress.

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 – Several major bridge and intersection replacement projects in southern Arizona presented a big challenge for the Arizona Department of Transportation in 2020: How to replace existing structures or entire interchanges without closing highways on projects that last up to two years.

The agency applied several innovative approaches to do just that, keeping passenger vehicles and commerce moving while minimizing potentially disruptive restrictions and closures.

The trip east from Superior on US 60 used to be a lot different, but the need to cross Queen Creek is timeless.

They say there is strength in numbers - and that is especially true when it comes to the girders used for bridges like the one on Interstate 17 over Central Avenue.

PHOENIX – The Arizona Department of Transportation will begin work to replace the Rio de Flag bridge along Historic Route 66 near Flagstaff City Hall. The work will involve the use of precast bridge components to significantly reduce the amount of traffic restrictions during the project. 

We are nearly half a year into our project to reconstruct the I-17 bridge over Central Avenue. While the project won't be finished until fall 2021, here's some photographic evidence of progress being made.

The Chevelon Creek bridge may not be part of a transcontinental highway anymore, but that doesn't make it any less impressive.

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

You may have missed the actual work, but you won't have failed to notice that a concrete pour has happened on our project at I-10 and Ruthrauff.

PHOENIX – Northbound Interstate 15 will be narrowed to one lane over Bridge No. 7 in the Virgin River Gorge for the next several weeks so the Arizona Department of Transportation can repair damage from an August crash involving a semi-truck.

Beginning at 6 a.m. on Monday, Oct. 12, northbound I-15 will be narrowed to one lane at milepost 22. Drivers traveling between Mesquite, Nevada and St. George, Utah should expect delays and allow extra travel time. Southbound I-15 traffic will not be affected by the work.

All the traffic may be on Interstate 8, but that doesn't mean this 90-plus-year-old bridge a stone's throw away isn't still doing its job.
