Bridges

It was 90 years ago that Arizona dedicated Navajo Bridge spanning the Colorado River at Marble Canyon.

The Ligurta Underpass is one of Arizona's best examples of clean design in a World War II-era rural bridge.

A celebration this week in 1915 included a parade of decorated automobiles, a concert and horse races.

Two years after construction began on an interchange connecting Interstate 10 and the Loop 202 South Mountain Freeway, crews have placed the final bridge girders needed for this huge Arizona Department of Transportation project in west Phoenix.

April 30 to May 9

Two slideshows take you through and above projects widening I-10 to three lanes in each direction in Casa Grande and near Eloy.

PHOENIX – A new bridge to carry Pinnacle Peak Road traffic over Interstate 17 will start to take shape over the next month as part of improvements coming to north Phoenix.

A bridge along historic Route 66 is a great early example of vehicular bridges in our state.

Motorists using Interstate 15 in far northwestern Arizona will need to budget extra travel time over the next year as the Arizona Department of Transportation improves the decks of three bridges through the Virgin River Gorge between St. George, Utah, and Mesquite, Nevada.

Take an interactive before-after look at a bridge demolition that's part of a project building a wider I-10 between Eloy and Picacho in central Arizona. 

No estimated time for reopening.

Watch as our drone flies over the demolition work on the old I-10 bridges at Jimmie Kerr Boulevard in Casa Grande and the new bridges that are part of a widening project there.

Whether today or 40 years ago, our highway engineers and crews are thinking about how to move traffic from one side to the other of the Salt River in Phoenix.

The largest structures on the Arizona Department of Transportation’s Loop 202 South Mountain Freeway project are nearly complete, with crews finishing the concrete decks of two half-mile-long bridges that will carry traffic over the Salt River in the growing southwest Valley.

Today's blog follows bridge piers deep underground to explain how they support overpasses that can carry thousands of vehicles every day.

See the progress we're making on replacing three bridge decks between Interstate 40 and Historic Route 66 near Seligman.

This effort is interesting beyond the wow factor, as it's a major step forward for a project widening 4 miles of I-10 to three lanes between Earley Road and I-8 in Casa Grande.

As the Loop 202 South Mountain Freeway advances, bridge girders are being installed this week at two of the 14 planned traffic interchanges.

Closure until December 2019
