As the before (left) and after photos above show, ADOT's Loop 202 South Mountain Freeway project is advancing quickly.

Monday morning commuters using I-10 through the South Mountain Freeway work zone in west Phoenix saw that progress first-hand Monday.

After a weekend of work, there are now mammoth support beams, each weighing 160,000 pounds and more than 170 feet long, above the westbound I-10 travel lanes east of 59th Avenue.

During a 44-hour westbound closure that began at 10 p.m. Friday, two large cranes worked in tandem to hoist and place 18 steel-reinforced concrete girders for a flyover ramp that will connect westbound I-10 with southbound Loop 202.

This weekend, Feb. 1-4, crews will set the remaining 12 girders for this ramp over the eastbound lanes, requiring a full eastbound closure.

There’s never a good time to close a freeway, particularly one as busy as I-10. But these closures are absolutely necessary to ensure the safety of the traveling public and construction workers as Connect 202 Partners, the developer of the South Mountain Freeway, moves toward opening to traffic as early as late this year.

What do you do with an old freeway when you’ve just built a new one?

In Pinal County, where we’re in the process of building new lanes of Interstate 10 near Eloy, the answer is an unexpected one: Recycle it.

Most of the time, freeway lanes are elevated slightly above the land on either side. That helps drain water when it rains, for example. Creating that elevation usually requires engineers to find additional dirt nearby, often from a borrow pit – nearby ground where removing the dirt won’t cause any environmental or economic problems.

But taking tons of dirt from one place and hauling it to another, sometimes over considerable distances, can be costly.

Now that both westbound and eastbound traffic has moved to the new lanes there’s no need for the old lanes. Arizona Department of Transportation engineers found a way to put the dirt, asphalt and concrete to a better use.

Almost as soon as westbound traffic started using the new lanes in December, we began removing the old lanes. By the time we’re done, we will have moved 16 lane-miles of freeway – 1 million square feet of asphalt, 30,000 feet of guardrail and tons of earth – to form the foundation of the new eastbound lanes.

The savings are considerable. The new I-10 lanes are only about 100 yards east of the old lanes, reducing the time and cost of moving materials from a distance borrow pit. The old guardrails that are in good condition will be saved and used in repair projects around Arizona.

Among the many recycling programs around Arizona, not one includes old freeways as a recyclable item. Not to worry. By putting old I-10 to use in building new I-10 in Pinal County, we’re doing our part.

On most road-building projects, there’s a lot of work you don’t see. From building foundations for new travel lanes to pouring concrete deep into the ground to support bridges, the progress isn’t always visible to drivers passing by.

As you can see in the video above, that’s been anything but the case on the project widening 4 miles of I-10 between Eloy and Picacho. Over the past six weeks, here’s what has happened:

  • Westbound traffic moved to the new westbound lanes in early December.
  • Crews removed the pavement, bridges and guardrails from the old westbound lanes.
  • Eastbound traffic has been moved to new pavement that eventually will be used for westbound traffic, separated from westbound traffic by concrete barrier.
  • The new overpass connecting I-10 with State Route 87 has opened, including both westbound ramps and a temporary eastbound ramp.
  • SR 87 has opened north of I-10, allowing traffic to connect from the freeway to central Arizona.

Next up: Removing the old eastbound lanes, finishing construction of the new eastbound lanes and implementing the innovation dust detection system designed to give drivers information to make them safe in a dust storm. We're also recycling asphalt and other materials to create the base for the new eastbound lanes.

It's all scheduled to be done by early fall.

When it comes to the art of transportation, few things are as striking as a bridge deck pour. In the video above and the photos below, a crew works through the night to put down concrete for the deck of an expanded I-10 interchange with Jimmie Kerr Boulevard in Casa Grande.

You'll even see a Bid-Well, the concrete-smoothing machine we told you about last week.

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 Interstate 8.

Late next year, when ADOT completes this project and another underway between Eloy and Picacho, I-10 will be three lanes all the way between Tucson and State Route 387 near Casa Grande.

PHOENIX – With the Arizona Department of Transportation covering the cost of training and providing safety gear for participants, dozens of members of the Yavapai-Apache Nation have completed a Construction Academy that helps them launch careers in transportation.

 

Among other instruction, the academy offers flagger certification and safety training required to work on construction projects within and around the reservation in the Verde Valley. In addition, some participants have received training required to obtain commercial driver licenses allowing them to drive for construction contractors.

It’s another example of ADOT’s On-The-Job-Training Supportive Services Program helping expand career opportunities for members of tribal nations. In 2017, a Construction Academy sponsored by ADOT helped members of the Tucson-area Pascua Yaqui Tribe earn certification to work on tribal construction projects.

“These partnerships with tribes are a natural extension of programs designed to connect people with opportunities in the transportation industry,” said Dr. Vivien Lattibeaudiere, ADOT’s employee and business development administrator. “Training offered through ADOT, through contractors, through community colleges and through other avenues connects members of disadvantaged groups, including those who are unemployed, with construction careers.”

Seven members of the Yavapai-Apache Nation who completed the most recent Construction Academy training also got hands-on experience in concrete masonry and carpentry trades through various construction projects on the reservation. In the process, those who completed all instruction offered over 16 weeks received six units of college credit in blueprint-reading, construction math, masonry and carpentry.

This latest phase of instruction, offered in collaboration with Gila Community College, expands a Construction Academy Pre-Apprenticeship Training Program that ADOT and the Yavapai-Apache Nation’s Tribal Employment Rights Organization (TERO) launched last year.

“The partnership with Gila Community College and ADOT has helped to educate and give practical skills to our tribal members,” said Brian M. Kelley, the Yavapai-Apache Nation’s TERO officer. “This was an opportunity that we needed and really enjoyed.”

ADOT’s On-The-Job-Training Supportive Services Program, part of the agency’s Business Engagement and Compliance Office, offers Construction Academy programs to help remove barriers to construction careers for members of disadvantaged groups, including minorities, women and those who are unemployed. ADOT’s commitment extends to helping participants move on to construction apprenticeships and providing support and guidance as they work toward journeyman status.

Various other Construction Academy opportunities are available around the state. Individuals also can receive training that will help them become concrete finishers, block masons, highway surveyors, heavy equipment operators and commercial drivers.

ADOT covers training costs and fees for participants and provides support including transportation and child care assistance, job-readiness training, and safety gear such as hard hats and protective eyewear.

During the recently completed federal fiscal year, ADOT’s On-The-Job Training Supportive Services Program received $112,000 from the Federal Highway Administration to offer workforce-development initiatives.

For more information or to apply for a Construction Academy, please visit azdot.gov/BECO, call 602.712.7761 or pick up materials at the ADOT Business Engagement and Compliance Office, 1801 W. Jefferson St., Suite 101, in Phoenix.

With one of two routes between I-40 and Seligman closing today for a project replacing bridge decks, we want to make sure everyone seeking an Old Route 66 fix knows there's still a convenient route to and from the interstate.

ADOT has worked with the community on ways to direct I-40 motorists to Exit 123, which connects with the on the east side of town. That includes signage along the interstate, as described in this video about Seligman, this project and the partnership between ADOT and the area's business community.

While I-40 Exit 121, leading to the west side of Seligman, remains open, that won't provide a link to and from Seligman until the project is completed. And this project doesn't affect through traffic on I-40 or Route 66.

South Mountain Freeway: Salt River Bridges - April 2018

By Steve Elliott / ADOT Communications

A project as large as the Loop 202 South Mountain Freeway makes for some impressive pictures, including the slideshow above produced as crews set extremely long girders to create two half-mile bridges that will span the Salt River.

There's plenty more to explore on the South Mountain Freeway Flickr page – 31 albums in all, from the start of construction on the 17th Avenue interchange to showcasing colors and designs to be used on interchanges and walls to creating the I-10 interchange in the West Valley.

You'll see some videos there as well, including this one showing one of the long, long Salt River bridge girders arriving at the construction site.

It had been since Thanksgiving that traffic rolled along Southern Avenue in Laveen near 59th Avenue. There was a good reason for that: Crews needed to move a lot of earth to finish the first phase of a Loop 202 South Mountain Freeway interchange project and reopen this busy road.

On Monday, traffic returned to Southern Avenue between 61st Avenue and 64th Drive. You can see it in the video above and slideshow below.

It’s no stretch to say that the residents are thankful to be using Southern Avenue again. Some, including school bus drivers, waved at us as they passed today.

Other than occasional overnight closures to complete a 125-foot bridge, Southern Avenue will remain open during phase two of the work.

Southern Avenue Reopening

“While closing Southern Avenue was certainly impactful to Laveen motorists in the last few months, in the long run this freeway will alleviate some of the growing traffic congestion on local roadways,” said ADOT Resident Engineer Adam Brahm, who oversees the Salt River segment of construction on the South Mountain Freeway.

Along State Route 89 at Yarnell Hill, a weathered bronze plaque on a highway marker honors C.C. Small as the “Father of Arizona Highways.”

But this 85-year-old memorial at Lookout Point offers no explanation of how Small earned this lofty title. So we visited yellowing pages in the state archives for an explanation. 

First we learned that Small gained his engineering experience working on railroads in the Southwest, Mexico and Bolivia before he turned to building Arizona roads a century ago.

He worked for the Arizona Highway Department during the 1920s, a pivotal era when Arizona and the nation were furiously creating roads for a surging number of motorists. The agency became Arizona Department of Transportation in 1974.

It was his position as location engineer, picking road alignments across desert and mountain terrain, that helped earn Small the title of Father of Arizona Highways – the roads, not the magazine.

Over his 13-year tenure, starting in 1919, Small presided over construction of what became Route 66, along with improvements to US 70 from Phoenix to Duncan and US 89 from Nogales to Flagstaff. A junior Highway Department staffer remembered Small as “the guy who ran the place,” according to an Arizona transportation history published for Arizona’s centennial in 2012.

In July 1925, Small wrote in Arizona Highways about choosing between two routes from Phoenix to Prescott for development of a modern highway.

In an understatement, Small noted there was “considerable controversy” between those favoring the route through Wickenburg and Yarnell to Prescott and supporters of the Black Canyon route through New River, Mayer and Dewey.

“After considerable study of the merits of the two routes it was decided that the Wickenburg route could be made a first class highway at less cost than the Black Canyon route,” he said.

That became the main route to Prescott until after World War II, when the Black Canyon Highway was developed through Cordes Junction and became the most direct route from Phoenix to Prescott. But Small did not live to see that. His death in April 1932 at age 58 shook the State Capitol.

In a proclamation, Gov. George W.P. Hunt praised Small:

Blog-2018-0314-certificate

“The people of this state have suffered a very serious loss in the death of Engineer C.C. Small, which to me is keenly personal. ...The many beautiful highways which wind in majestic splendor from one end of the state to the other constitute living proof of his enormous skill, for as you know Mr. Small played a very prominent part in their construction.”

Flags at the Arizona Capitol were lowered to half-staff.

Small was also honored by his peers at the American Society of Civil Engineers in November 1933 with the dedication of the memorial south of Yarnell at Lookout Point. But the plaque, with a bas relief caricature of Small, didn’t include details of his life and remarkable career.

Charles Churchill Small was born Jan. 12, 1874, in North Truro, Massachusetts, on Cape Cod, to Levi and Rebecca Small. At age 16, Small started his engineering career with the New York, New Haven and Hartford Railroad, according to Arizona Highways magazine. He was self-taught and not a college graduate.

Small then left New England to work in Mexico for the Chihuahua & Pacific Railway and the Mexico Central. The Chihuahua & Pacific started plans in 1880 for what would become the 400-mile route from Chihuahua City to Los Mochis, Sinaloa, through Copper Canyon. It is one of North America’s most scenic railroads and an engineering marvel with 86 tunnels and 37 bridges.

The Chihuahua & Pacific company faltered, and the entire route wasn’t completed until 1961. But it’s possible Small had at least some input into its early designs.

At the outset of the 20th century, Small returned from Mexico to the United States to work over the decade for a series of railroads, including El Paso & Southwestern, Southern Pacific and Santa Fe railroads. El Paso & Southwestern was developed by copper interests to serve mines in Arizona, New Mexico and Mexico. The 1902 train station in Douglas built by El Paso & Southwestern is still in use as the city’s police headquarters.

Small also worked for railroads in Mexico and Bolivia during this decade.

Records found by David Newlin, a history buff and avid genealogist, sketch out Small’s employment arc in the second decade of the century.

A 1910 census document shows Small was working as chief engineer for railroad construction at a mine near Tyrone, New Mexico. He was listed as single, and it’s unclear if he ever married.

In September 1912, Small went to Guatemala to work for a railroad, according to a State Department document. He was authorized to stay in the country through April 1914.

 

In 1918, Small registered for the World War I draft in Yavapai County at age 44. He listed his occupation as chief engineer for the United Verde Extension Mine in Jerome, which hit a supremely rich vein of copper in 1916 and made James S. “Rawhide Jimmy” Douglas fabulously rich.

A year later, Small went to work for the Arizona Highway Department. During his tenure, the state’s highway inventory doubled to 2,000 miles. The department was moving so fast it was using three miles of blueprint paper annually with all its highway plans.

Small worked under five state engineers and with dozens of other engineers. The Arizona Highway Department by the mid-1920s was the state’s largest employer as road-building ramped up to meet demand. Small was appointed deputy state engineer in 1928.

In that job, he started construction of a difficult stretch of US 60 from Globe to Show Low that included the bridge in Salt River Canyon.

Beyond his engineering expertise, Small was hailed as a man of integrity and decency, according to his obituary in Arizona Highways:

“Kindly and retiring, a host of many friends mourn his passing, from the laborer who worked under his direction to the head of the highest financial institutions in the state. His reputation for fair dealing is a proud record for any man to leave behind, and time will prove the excellence of his roads.”
