ADOT seeks public input on options for US 60 bridge at Pinto Creek

Posted on by

PHOENIX – The Arizona Department of Transportation is seeking public input on options for the US 60 bridge over Pinto Creek, including the agency’s decision to pursue removing and replacing the structure.

Built in 1949, the 637-foot-long Pinto Creek Bridge, located east of the Valley between Superior and Miami, no longer meets minimum standards set by the Federal Highway Administration, the American Association of State Highway and Transportation Officials and ADOT’s bridge design guidelines. Though it continues to be safe for traffic, the structure is considered structurally deficient and functionally obsolete.

In accordance with federal law governing proposed transportation projects involving sites with historic significance, ADOT is seeking public input on possible courses of action for the Pinto Creek Bridge. These are:

  • Building a new bridge and removing the existing bridge, the action that ADOT and the Federal Highway Administration have decided to pursue
  • Rehabilitating the existing bridge
  • Building a new bridge and rehabilitating the existing bridge
  • Taking no action

The Arizona Federal Highway Administration office has completed a report, Programmatic Section 4(f) Evaluation and Approval for FHWA Projects that Necessitate the Use of Historic Bridges, which is posted at azdot.gov/PintoCreekBridge. Comments can be submitted by email to PintoCreek@azdot.gov, by calling the ADOT Project Information Line at 855.712.8530 or by mail to:

ADOT Communications

Phoenix, AZ 85007

Comments must be received by December 8 to be included in the official project record.

ADOT applies for TIGER grant to expand SR 189 project starting in 2019

Posted on by

NOGALES ‒ The Arizona Department of Transportation has applied for a $25 million federal TIGER grant to allow construction of all proposed improvements to State Route 189 in Nogales at the same time, beginning in 2019.

The $25 million Transportation Investment Generating Economic Recovery grant would go toward construction of a southbound flyover ramp at Interstate 19 in addition to the northbound flyover ramp that’s currently funded, as well as a bridge over Frank Reed Road and other improvements to the 3.75-mile route connecting the Mariposa Port of Entry with I-19.

“ADOT is committed to working creatively with the community to accelerate State Route 189 improvements and better support trade between the U.S. and Mexico,” ADOT Director John Halikowski said. “Seeking this TIGER grant is one way we’re seeking to move forward sooner with all proposed enhancements to a route vital to international commerce and to the community of Nogales.”

ADOT currently has funding for the first phase the project, which includes a flyover ramp connecting northbound SR 189 and northbound I-19, along with other improvements. A $25 million commitment from the Arizona Legislature signed by Governor Doug Ducey allowed ADOT to begin construction in 2019, two years earlier than originally planned.

Funding isn’t currently identified for Phase Two, which would include the southbound flyover ramps and a bridge that would carry SR 189 over Frank Reed Road, which leads to Nogales High School. ADOT, Nogales and Santa Cruz County are coordinating efforts on a partnership that could include funding for the Phase Two work.

By allowing construction of both phases to begin at the same time, the TIGER grant would reduce the estimated cost of the full project from $147 million to $134 million.

A $15 million TIGER grant is helping to fund work on the SR 347 bridge over the Union Pacific Railroad tracks in Maricopa, which will begin in November. Another TIGER grant of $21.6 million went toward the rehabilitation of Virgin River Bridge No. 6 on Interstate 15 in far northwestern Arizona.

Since 2009, Congress has dedicated nearly $5.1 billion in TIGER grants to fund projects that have a significant impact on the nation, a region or a metropolitan area.

National association honors Interstate 15 bridge project

Posted on by

PHOENIX – A national industry group has honored the Arizona Department of Transportation’s $30 million rehabilitation of an Interstate 15 bridge through the rugged Virgin River Gorge in far northwestern Arizona.

The American Public Works Association selected the Virgin Bridge No. 6 improvement, completed last year, as Project of the Year among transportation projects worth between $25 million and $75 million, with ADOT as the managing agency, Pulice-Wadsworth Brothers Joint Venture as primary contractor and Jacobs as primary consultant.

“This award acknowledges the creativity and cooperation that went into making a critically needed improvement to a vital regional economic corridor,” said Dallas Hammit, ADOT state engineer and deputy director for transportation.

Upgrading the 50-year-old bridge was the centerpiece of $50 million in upgrades to the 30 miles of I-15 passing through Arizona, including paving the entire stretch and repairing the decks of three other bridges.

At Virgin River Bridge No. 6, crews replaced girders, decks and railings and widened the roadway. Accomplishing that required 4,000 cubic yards of structural concrete, 3 million pounds of structural steel, 910,000 pounds of reinforcing steel, 4,000 tons of earth moved and 3,600 tons of asphalt.

A $21.6 million Transportation Investment Generating Economic Recovery (TIGER) grant ADOT won for the project in 2014 provided three years for ADOT to complete the design, for the project to receive environmental clearance and for crews to complete the bridge upgrades.

The project’s challenges also included the rugged, remote location. The bridge stands 100 feet above the Virgin River in a narrow canyon, requiring specialized equipment to work in tight spaces. ADOT and its partners also worked closely with agencies including the Bureau of Land Management, Arizona Game and Fish Department, Arizona State Land Department and Environmental Protection Agency to safeguard the river.

Among other honors, the Virgin River Bridge No. 6 rehabilitation has been named International Partnering Institute Partnered Project of the Year and has received the Marvin M. Black Partnering Excellence Award as part of the Alliant Build America Awards.

ADOT’s current five-year construction program commits $50 million in fiscal 2020 to renovate Virgin River Bridge No. 1 near Littlefield and $5.5 million in fiscal 2019 to rehabilitate other I-15 bridges.

Please help locate a bit of Arizona Highways history

Posted on by

PHOENIX – Since it began showcasing the state’s beauty and diverse landscapes, Arizona Highways has been a collector’s item. People around the country have not only subscribed but held on to the monthly issues of the magazine, produced by the Arizona Department of Transportation, so they could go back again and again to look at the photos and read about the history.

Now Arizona Highways needs a little help finding a piece of its history, in this case a December 1930 issue to add to its digital collection.

“We know that many of you are collectors,” editors shared on the magazine’s Facebook page. “Is there any chance one of you could give us a hand in locating a copy?”

Editors say they’d like to have a copy of the December 1930 edition to keep, but they’d gladly scan and return the edition if the owner wants to keep it.

Arizona Highways began as a simple newsletter in 1921 and became a magazine in April 1925. From the beginning, it contained travel stories and scenic photographs. In the early years the photos were black-and-white, and the magazine contained page after page detailing the Arizona Highway Department’s (now the Arizona Department of Transportation’s) road-building projects. Editors added cartoons to liven up those pages.

Arizona was one of several states to develop a magazine to entice drivers to explore their newly developed roads. Of these magazines, none dates as far back or has featured the iconic photography that has made Arizona Highways a national treasure.

If you can help by sharing a December 1930 edition of Arizona Highways, please contact the magazine through its website at arizonahighways.com.
