Bridges

In a little more than a month you’ll be able to drive along the new bridge on I-15 through the Virgin River Gorge in northwest Arizona. Here's what you'll be driving on.

Today we’re taking you on a unique drive through Cameron on US 89 north of Flagstaff.

While the name often leads to a few jokes, the new SR 89 Hell Canyon Bridge will have some heavenly features.

Check out our new video showing how crews place massive girders for the new Hell Canyon Bridge.

Residents will have a more reliable link with Yuma County’s largest employer, Yuma Proving Ground, thanks to a 600-foot bridge ADOT is building across a flood-prone section of US 95.

PHOENIX ‒ Arizona Department of Transportation engineers in Phoenix will get real-time information on the conditions of four interstate bridges in remote northwestern Arizona thanks to technology funded by a $768,000 Federal Highway Administration grant.

To enhance safety and efficiency, ADOT will use the Accelerated Innovation Deployment Demonstration grant to add structural health monitoring systems to the Interstate 15 bridges, embedding sensors on the superstructures that record, analyze and share data.

ADOT works very closely with all of its project partners, including emergency responders, local governments and contractors.

A bridge replacement project on Interstate 10 westbound between Tucson and Benson will require a 67-mile detour from 9 p.m. Tuesday, Nov. 17, to 5 a.m. Wednesday, Nov. 18.

We have an update for you on the Hell Canyon Bridge replacement project that isn’t infernal at all!

ADOT is working to construct a wider bridge while limiting SR 89 traffic impacts during construction.

PHOENIX — While the Arizona Department of Transportation completed interim repairs to the Hell Canyon Bridge in 2013, the agency moved forward with plans to design a new bridge along State Route 89 in Yavapai County that would ultimately replace the aging and narrow bridge that does not meet today’s design standards. Two years later, ADOT will start construction on Tuesday, July 14 on a modernized bridge that will replace the current bridge when completed.

We’ve been following the US 89 Cameron roadway improvement project pretty closely here on the blog.

ADOT has been recognized for its environmental protection efforts while rebuilding the San Pedro Bridge through a sensitive conservation area on State Route 90 east of Sierra Vista.

If you’ve driven recently on the Loop 202 Red Mountain Freeway, you might recognize the structure pictured in today's post.

Work continues on the US 89 Cameron roadway improvement project.

Get details on the I-15 Virgin River Bridge No. 6 rehabilitation project, along with a look at what drivers can expect in the work zone.

It’s been a while since we checked in on the Virgin River Bridge No. 6 rehabilitation project that’s happening up in the far northwestern corner of the state, but as you can see crews have kept busy.

Work continues on the US 89 Cameron roadway improvement project in northern Arizona.
