Tangerine Road Project Keeps Crews Busy in Oro Valley

By Chuck Harvey CEG CORRESPONDENT

Crews are widening Tangerine Road — an important east-west connection between I-10 and SR 77 north of Tucson — and turning it into a modern multi-use desert parkway.

As a parkway, it will be a broad, landscaped highway thoroughfare designed for commuters as well as sightseers out for a recreational drive.

The Tangerine Road Improvement Project includes widening the roadway from two to four lanes and constructing sidewalks for pedestrians and new lanes for bicyclists. Multi-use lanes and bicycle lanes will be constructed throughout the project.

“There will be pedestrian paths provided away from the road,” said project spokeswoman Genna Dreier, public relations coordinator and branding specialist for Kaneen Communications in Tucson.

Crews also will install turn

lanes, traffic signals and wildlife crossings.

Signalized crossings include Dove Mountain Boulevard, Camino de Oeste, Thornydale Road and La Cholla Boulevard.

In addition, workers will install landscaped medians, eliminate existing dip crossings and upgrade culverts to avoid closures caused by flooding.

Eliminating dip crossings will be significant in improving the drive on Tangerine Road. “It will be much smoother,” Dreier said.

Work spans 10 mi. (16 km) on both sides of West Tangerine Road from North Dove Mountain Boulevard to North La Canada Drive. The segment falls within Oro Valley, the town of Marana and Pima County.

TCC, a Granite Construction and Borderland Construction joint venture, is contractor for the project. Tom Houle is project manager.

Resolution to Collect Data for Proposed Storage Facility Neil Bosworth, forest supervisor has approved both an environmental assessment and a plan of operations allowing Resolution Copper Mining LLC, to gather necessary data to help evaluate possible construction of a large tailings storage facility on National Forest Lands.

Bosworth approved the environmental assessment Aug. 22, and the plan of operations Aug. 24. The approvals do not authorize the construction of the tailings storage facility itself but rather only allow for the acquisition of data related to groundwater and soils via construction of wells, test pits, forest road improvements and laydown yards. The proposed tailings facility would encompass an area approximately 6,400 acres in size.

Baseline activities will affect approximately 75 acres located on public lands managed by the Tonto National Forest approximately 4.5 mi. (7.2 km) west of Superior, Ariz. Activities will include construction of temporary access roads and drilling/trenching sites; improvement of existing access

roads; and installation of groundwater monitoring wells, geotechnical bore holes and trenches. All activities are outside of the Oak Flat area where the proposed underground copper mine is planned and will not impact camping and recre-

ation activities near Oak Flat.

According to Bosworth, the project formally identified as the “Baseline Hydrological and Geotechnical Data Gathering Activities Plan of Operations” will allow Resolution Copper Mining

to gather critical information necessary for the evaluation of the proposed facility.

“Data provided from this project will be critical to understand the baseline environmental conditions and to support a reasoned choice

among alternatives for the proposed tailings facility in the ongoing Environmental Impact Statement under way for the larger mine development proposal,” Bosworth said. “The project also will provide data that will inform Resolution Copper Mining’s ongoing design efforts for the proposed tailings facility.”

These approvals conclude a rigorous three-year review period during which numerous public comments were received and project modifications were made by Resolution Copper Mining to mitigate project impacts.

As part of the federal authorization for this project, Resolution Copper Mining has provided a bond in the amount of $1.45 million to guarantee adequate reclamation of any disturbances caused by project activities.

Last Remnants of Historic Phoenix Power Plant Built in 1930s Demolished PHOENIX (AP) The last remnants of a historic power plant in Phoenix have been demolished.

The Phoenix Power Plant off 43rd Avenue near Buckeye Road was imploded shortly after 7 a.m. on Oct. 1.

Emissions stacks of 200-ft. (61 m) and 135-ft. (41 m) and a water tower came down at the site of the plant that was originally built in 1930 and expanded with five generators through 1950.

In 1965, the first three generators were dismantled and sold to Mexico.

The last time generators at the old steam plant ran was in 2001.

The demolition project will cost Arizona Public Service Co. more than $6 million after earning back some of the expense by selling about 3,000 tons of scrap metal.

Northern Vertex

In addition, David Stone has been appointed Northern Vertex’s construction project manager. Stone will be responsible for overseeing the design, procurement and construction activities of M3 and other site based contractors engaged

by M3 as the mine is built.

Stone has authored numerous prefeasibility and feasibility studies and was most recently one of the co-authors of the feasibility study referred to above. He has extensive experience in the design and construction of heap leach mines dating back to the 1980’s including Beal Mountain in Montana, Basin Creek in Montana, Yellow Aster in California, Manhattan in Nevada and Brewery Creek in the Yukon.

Stone will report directly to Dick Whittington, Northern Vertex’s president and CEO. Whittington stated, “We are delighted to have both M3 and Dr. Stone formally join our team as we look to move the Moss Mine forward to production. M3 has extensive experience in the design and construction of processing facilities for mines around the world and has a track record of building them on time and on budget. Meanwhile, Dr. Stone will provide invaluable input and guidance to the construction build process as we look to implement the mine and processing designs outlined in the feasibility study. We are excited to be pressing the starting gun on building one of the most economically robust, high margin, projects in one of the premier mining jurisdictions in the world. We look forward to transforming the company from a development story to a production story over the coming year.”

Implosion Technique Causes Bridge to Collapse on Itself BRIDGE from page 1

ADOT photo

Crews began dismantling the old bridge in August by removing the bridge deck.

Contractors then used an implosion technique that caused the bridge girders to melt and allow the structure to collapse onto itself.

The new Hell Canyon Bridge, located about 18 mi. (29 km) north of Chino Valley between Prescott and Ash Fork, carries about 3,400 vehicles each day.

The new $14.4 million bridge is 665 ft.

(202.6 m) long and 47 ft. (14 m) wide — 65 ft.

(19.8 m) longer and 17 ft. (5 m) wider than the structure it replaces — and has added strength from a fourth span. It has 12-ft. (3.6 m) lanes and 10-ft. (3 m) shoulders in each direction, allowing it to better accommodate oversized loads.

Safety, Access, Flow All Part of Tangerine Road Redesign ROAD from page 1

Tom Houle, Town of Marana photo

Granite Construction partners with federal, state and private entities to design and build roads and highways. Borderland Construction is a heavy civil project contractor based in Tucson.

It specializes in construction management of bridges, roads and highways. In addition to paving and grading, Borderland performs its own structural concrete, curb and flat work.

Safety, Easy Access — Important to Design Designed to improve safety, access and traffic flow, the Tangerine Road project is a partnership between Pima County, Oro Valley, Marana and the Regional Transit Authority.

It is part of a $2.1 billion Regional Transportation Authority plan approved by voters in 2006.

It is a construction management at risk project that combines the efforts of the design-engineering team, the owner and the contractor.

Construction began in March of this year. Phase 1-A, from Dove Mountain Road to Thornydale Road should wrap up in 2017.

Phase 1-B, from Thornydale Road to La Canada Drive, is slated to be completed in 2018.

Phase 2 construction, from Dove Mountain Boulevard to I-10, could start in 2022, according to project documents.

Improving Travel, Emergency Services Improvements will reduce congestion and travel times. In addition, the elimination of the dip wash crossings will eliminate the need for road closures and allow emergency services to respond faster during major storms.

contains a curbed landscaped median and uncurbed road edges and is intended for roadways with posted speed limits of 45 mi. (72 km) per hour or lower. The design is appropriate for segments of a roadway that experience lower speeds because of more intersections and driveways.

Crews will follow the uncurbed desert parkway design in building the higher speed segment of Tangerine Road from I-10 to Thornydale Road. The remainder of the Tangerine Road project to the east will feature the curbed desert parkway design.

Landscaping would include plants near the roadway and trees near walking paths on each side of the road. Trees could also be planted on the median of the curbed parkway.

It is part of a design that incorporates both safety and aesthetics.

As a desert parkway, the road design and landscaping will complement the desert scenery.

Tangerine Road also will accommodate bicycle riders and pedestrians. Bicycle lanes and shoulders are incorporated into the roadway design, as are nearby pedestrian paths.

Small Businesses in Construction Area Can Seek Help The Regional Transportation Authority funds Main Street Business Assistance, a small-business assistance program. The RTA plan approved in 2006 provides $10 million for small business assistance affected by road improvement projects that are part of the plan.

The funding is used to provide information, facilitate communication and provide consulting services to businesses.

Dust Mitigation Marana, Oro Valley and Pima County developed provisions that require the contractor to water the work area on a regular basis to reduce particulates and dust.

Noise reduction also was considered, but the amount of noise produced by the project did not meet the criteria for noise wall installation in areas near the work.

Arizona’s Crushing & Screening Authority

New Fortuna Wash Bridge to End Rain Delays on U.S. 95 Drivers who have been anticipating a new bridge to carry U.S. 95 traffic over the floodprone Fortuna Wash don’t have much longer to wait. The bridge is expected to begin taking traffic by the end of November.

Final work should be completed by spring, but only minor traffic interruptions are expected after the bridge opens to traffic.

U.S. 95 is the only north-south route connecting Yuma with Interstate 10 and Arizona locations along the Colorado River. Until now, it has taken drivers through the wash and has been subject to unexpected closures during heavy rains.

The bridge will make U.S. 95 a safer and more-reliable route for agriculture, international trade and seasonal visitors.

“This bridge is a crucial safety project and will be a huge benefit for the entire region,” said Paul Patane, ADOT Southwest district engineer. “Motorists and commercial vehicles rely on this roadway every day, and with this they can be confident that they won’t be stopped when the wash is flooded.”

The bridge also will make travel more reliable for employees and cargo shipments

“This bridge is a crucial safety project and will be a huge benefit for the entire region.”

at Yuma Proving Ground, a U.S. Army facility with more than 3,000 military and civilian employees. The area’s largest employer, it is one of the largest military installations in the world and home to General Motors’ hotweather vehicle test facility. It has an economic impact of more than $430 million annually.

The Fortuna Wash bridge is designed to accommodate four lanes of traffic but will be initially striped for two lanes with centerturn lane. The $15 million cost is partially funded by a $3.2 million federal grant.

Teaching the Next Generation...

ADOT Internships Prepare Transportation Professionals Arizona’s network of highways requires transportation professionals specializing in areas as wide-ranging as planning routes, repairing bridges and creating beautiful landscaping along roadways.

To help ready the next generation of professionals to plan, operate and maintain a safe and efficient transportation system, the Arizona Department of Transportation employs nearly 40 interns whose work touches projects in every corner of the state.

Coming from communities across Arizona, the interns work in fields including engineering, urban planning, construction management, environmental science, landscape architecture and more.

Earlier this year, ADOT partnered with Arizona State University to have meteorology interns provide real-time forecasts to those managing highways. Working out of ADOT’s Traffic Operations Center, these interns have helped crews respond rapidly to storms and other weather challenges.

ADOT recruits interns from high schools and colleges every spring, and interns can work for the agency throughout their college careers and up to six months after graduat-

“The interns I talk to love the program. They say they love school but there’s nothing that can replace the hands-on training they’re getting at ADOT.” Candee Samora Arizona Department of Transportation

ing. Typically working one day a week, they tackle the same kinds of projects they’ll face after graduating.

Interns benefit from the experience of working with a supervisor plus a designated mentor.

“The interns I talk to love the program,” said Candee Samora, ADOT’s intern project coordinator. “They say they love school but there’s nothing that can replace the hands-on training they’re getting at ADOT.” One of ADOT’s interns is Yuri LechugaRobles, an Arizona State University landscape architecture student who graduated in

May as the 2016 Outstanding Undergraduate Student for the Herberger Institute for Design and the Arts. LechugaRobles’ position in roadside development has allowed him to work on freeway projects in northern Arizona, Tucson and the Phoenix area. One of the lasting impacts of his work with ADOT Roadside Development is helping choose plants to go along roads and the graphic designs on bridges.

“Everyone in Roadside Development has been very helpful,” he said. “They’ve really taken care not to hold back and they’ve put me in situations where I can do things and

learn. They’ve had confidence in me.”

Lechuga-Robles received the John E. McGee Intern Scholarship in 2015 from ADOT and the Western Association of State Highway and Transportation Officials. He was the first landscape architecture student awarded the scholarship named after McGee, the late ADOT chief financial officer.

“A lot of what I’m doing at school is directly related to the projects I do here,” Lechuga-Robles said. “It’s definitely been enriching to my career in landscape architecture.”

LeRoy Brady, ADOT’s chief landscape architect, said the agency gets just as much out of the experience as its interns do.

“Interns help us meet our project development goals and schedules,” Brady said.

“They bring in new ideas and new ways of looking at things.”
