Bridges

A 100-year-old bridge has a new shine to it after a major makeover.

Check out a video showing Arizona's first prefabricated bridge going up in less than four days.

After more than five years of planning, work will begin in less than six months on a bridge carrying SR 347 over railroad tracks in Maricopa.

PHOENIX – With work on a State Route 347 bridge over the Union Pacific Railroad tracks in Maricopa set to begin later this year, the public will have another opportunity to review plans at a public meeting on Wednesday, April 5.

The $55 million project includes a bridge over the railroad tracks, a new intersection with Maricopa-Casa Grande Highway and a new alignment just east of the current route.

It didn't happen quite as quickly as it might seem from the time-lapse video above, but as bridge projects go this job in northwestern Arizona was lightning fast.

PHOENIX – The Arizona Department of Transportation is getting ready to install Arizona’s first prefabricated bridge along Oatman Highway, also known as old Route 66, with the help of Mohave County and the Federal Highway Administration.

The 110-foot bridge, manufactured in Phoenix and then transported in sections to the site in northwestern Arizona, will carry traffic over Sacramento Wash, a mile north of Interstate 40 in Topock. Supports have already been built along the roadway, awaiting installation of the prefabricated bridge next week.

This is a big step forward for a $120 million project creating a modern traffic interchange in a busy area northwest of Tucson.

A four-lane bridge near Yuma means travelers no longer have to wonder whether the weather will stop their journeys.

In response to community concerns, ADOT recently completed protective fencing on Midgley Bridge north of Sedona.

What do residents think about the new Bell Road bridge at Grand Avenue (US 60)? An ADOT video has their perspectives.

YUMA – Yuma-area drivers no longer have to worry about sudden rainstorms flooding Fortuna Wash and shutting down US 95, the area’s primary north-south route.

Starting Thursday, Dec. 15, traffic will begin flowing over a new bridge connecting Yuma with Interstate 10, Quartzsite and the rest of western Arizona. The bridge is expected to open Thursday afternoon.

If you think the overpass under construction at Bell Road and Grand Avenue (US 60) looks just about ready for traffic, you're right.

PHOENIX – The 62-year-old State Route 89 bridge at Hell Canyon will be removed on Sept. 16.

The Arizona Department of Transportation replaced the 1954 bridge, which no longer met state and federal design standards for larger and heavier vehicles, earlier this year. The new bridge is better able to accommodate commercial traffic, particularly oversized loads, between Prescott and Interstate 40.

Crews are replacing a 61-year-old bridge over the San Pedro River with a better bridge – without ever stopping traffic from using the old one.

PHOENIX – Southern Arizona drivers can expect minor delays for the next eight months on State Route 92 in southern Cochise County as crews work to replace a 61-year-old bridge over the San Pedro River.

The bridge will close from 7 a.m.  to 3 p.m. on Monday, Sept. 12, so Arizona Department of Transportation workers can put temporary striping, construction barriers and a traffic signal in place. Drivers will use Palominas and Hereford roads as an alternate.

PHOENIX – When crews completed Interstate 15 through the rugged Virgin River Gorge in 1973, the 29-mile stretch in northwest Arizona was one of the most challenging projects to date in the U.S. interstate system.

Among other projects along this stretch in the past two years, the Arizona Department of Transportation’s $27 million rehabilitation of Virgin River Bridge No. 6 has been challenging as well, not just for those doing the work but for motorists facing lane restrictions.

PHOENIX ‒ The new State Route 89 bridge at Hell Canyon is longer, wider and better able to accommodate commercial traffic between Prescott and Interstate 40 than the 62-year-old span it replaces.

The Arizona Department of Transportation opened the $14.4 million bridge to traffic Thursday, June 23, after 13 months of work.

Continuous improvement is an exciting way of looking at how we do business at ADOT. We look forward to sharing this story with you.
