PHOENIX – To reduce traffic backups from crashes, congestion and other incidents along Interstate 17 north of Phoenix, the Arizona Department of Transportation is evaluating options that include the possibility of reversible lanes on the grade between Black Canyon City and Sunset Point.

The reversible-lane concept (the video above shows an animation of what a system could look like) is among alternatives being considered to move more traffic while enhancing safety along that winding eight-mile stretch of I-17.

Regardless of whether reversible lanes become a reality, ADOT’s goals include expanding I-17 capacity along more than just those eight miles. As part of the state’s Key Commerce Corridors plan, which proposed investments in interstates and other highways to support economic growth, ADOT recommended widening I-17 to three lanes north of Anthem Way.

“I-17 is vital for passenger and commercial traffic between Phoenix and northern Arizona communities,” ADOT Director John Halikowski said. “We’re determined to identify options to increase the lane capacity along the highway while also working with the Department of Public Safety and other partners to reduce driver behaviors that lead to crashes and cause unnecessary delays. Drivers can be a big help in this effort by exercising patience and good judgment to improve safety in that area.”

With the State Transportation Board’s approval of ADOT’s five-year construction program last June, $3 million is being used this fiscal year for preliminary design work on alternatives for the corridor between Black Canyon City and Sunset Point. Another $5 million has been set aside in fiscal 2020 for final design.

A possible design for reversible lanes would feature a barrier at each end of the system that would be adjusted to open additional lanes in one direction of travel at any one time. For example, the lanes would be available for northbound traffic to use at the beginning of a weekend or available for southbound traffic on a Sunday afternoon or evening.

A preliminary design has estimated the construction costs for such a system at $125 million. While no funding is currently available for a reversible-lane system or widening projects, ADOT is aggressively seeking solutions including the possibility of a public-private partnership that could move a large project along sooner and at a lower cost.

More immediately, ADOT later this year will launch a safety-based project to add six electronic “speed feedback” signs along I-17 north of the Phoenix area. Those signs will display vehicle speeds while reminding drivers of the posted speed limit. ADOT’s project also will add four new electronic message signs to provide information about highway conditions along with safety messages.

PHOENIX – With Valley drivers benefiting from several freeway improvement projects completed during 2016, including the widening of Loop 101 between Shea Boulevard and Loop 202 (Red Mountain Freeway) in the Scottsdale area, the Arizona Department of Transportation is poised to start or complete several Phoenix-area projects in the coming year.

ADOT’s highlights for the regional freeway system in 2017 include:

  • Beginning construction of the Loop 202 South Mountain Freeway. Work scheduled for the first half of 2017 includes setting foundations for some of the 40 bridges planned, widening eastbound lanes of Pecos Road to accommodate two-way traffic during construction, creating access roads near the freeway’s future interchange with Interstate 10 in west Phoenix and creating drainage structures. This 22-mile direct link between the East Valley and West Valley will open by late 2019.
  • Opening the south half of the Interstate 10/Loop 303 interchange in Goodyear by fall. The $63 million project, launched last February, will complete freeway-to-freeway ramps and extend Loop 303 south to Van Buren Street. Loop 303 traffic will then have direct connections to and from Cotton Lane south of I-10. The north half of the I-10/Loop 303 interchange opened to traffic in August 2014.
  • Resurfacing an 11-mile stretch of Interstate 17 between 19th and Peoria avenues in Phoenix in spring 2017. Crews will add a new layer of smooth, durable rubberized asphalt along the Black Canyon Freeway when warmer spring weather provides the best conditions for the resurfacing work. Rubberized asphalt, which has been used on Valley freeways for several years, includes rubber from shredded recycled tires as part of the pavement’s mixture.
  • Completion of the new Bell Road/Grand Avenue interchange in Surprise by spring 2017. The $42 million project started last February. Crews opened the new bridge carrying Bell Road over Grand Avenue and the parallel BNSF Railway tracks on Nov. 22. New ramps connecting Grand Avenue to and from the Bell Road bridge are scheduled for completion in time for the Cactus League baseball season in late February.
  • Installing Loop 202 (Santan Freeway) traffic-management technology between Ray and Broadway roads in Mesa. The project, scheduled to start by summer 2017, will add several overhead message signs, closed-circuit traffic cameras and traffic-flow sensors along the Santan Freeway. The technology allows ADOT to provide travelers with updated freeway conditions. A current ADOT Freeway Management System project along Loop 202 between Dobson and Ray roads is scheduled for completion in spring 2017.

ADOT’s 2016 Valley freeway construction accomplishments include:

  • Completing $109 million in Loop 202 (Red Mountain Freeway) improvements between Loop 101 and Broadway Road, adding new travel lanes between Loop 101 and Gilbert Road, extending HOV lanes by 11 miles between Gilbert and Broadway Roads and resurfacing the roadway with rubberized asphalt.
  • Completing $74 million in Loop 101 (Pima Freeway) improvements between Shea Boulevard and Loop 202 (Red Mountain Freeway) in the Scottsdale area, a project that added new right lanes and paved 11 miles of roadway with rubberized asphalt.
  • Widening Loop 303 to three lanes in each direction between Grand Avenue (US 60) and Happy Valley Parkway in the northwest Valley, a $30 million project that wrapped up in 2016 with rubberized asphalt paving.
  • Performing preliminary construction for the Loop 202 South Mountain Freeway.  Work began in September with improvements to the I-10/Loop 202 Santan Freeway interchange in the Ahwatukee area.
  • Opening State Route 51 ramps to and from Black Mountain Boulevard at the Loop 101 (Pima Freeway) interchange. ADOT teamed with the city of Phoenix on this $17.8 million project to improve access in the Desert Ridge area of northeast Phoenix.

ADOT works with the Maricopa Association of Governments, the Phoenix area’s metropolitan planning organization, to schedule and deliver projects as part of the 20-year Regional Transportation Plan approved by Maricopa County voters in 2004. Funding sources include a countywide half-cent sales tax dedicated to transportation improvements as well as the Phoenix region’s share of state and federal transportation funds.

PHOENIX ‒ Southbound Interstate 17 will be reduced to one lane until Saturday, Dec. 24, at Orme Road, between State Route 169 and State Route 69, as crews make critically needed repairs at the bridge, according to the Arizona Department of Transportation.

ADOT normally doesn’t perform work requiring lane restrictions over holiday weekends, but engineers have determined that these repairs, involving concrete on the bridge approach, must be performed immediately.

I-17 is narrowed to one lane between mileposts 270 and 269 approaching Cordes Junction.  Northbound travel isn’t affected.

Southbound I-17 motorists should plan for delays, proceed through the work zone carefully and watch for construction personnel and equipment. While the work is scheduled to be completed on Saturday, bad weather can delay completion of projects.

Indian School and I-17 Intersection

By Caroline Carpenter / ADOT Communications

We’ve all heard that time is money. ADOT worked with the city of Phoenix and Maricopa Association of Governments to save motorists 350,000 hours of travel time, worth $6.2 million per year.

How did the three agencies make that happen? ADOT and city of Phoenix engineers worked together to develop a common cycle length for the traffic signals near Interstate 17 and Indian School and I-17 and Camelback. The project was funded by the Maricopa Association of Governments’ Traffic Signal Optimization Program.

ADOT Director John Halikowski and Phoenix Mayor Greg Stanton both expect the public will see multiple benefits from these improvements. Find out what else they had to say by reading our news release.

Improving signal timing at these busy intersections also improves safety by reducing the number of stops drivers have to make and time spent at traffic lights. The improvements will also reduce fuel consumption and air pollution.

ADOT and Phoenix will continue to evaluate other I-17 interchanges to see if changes in signal coordination can improve traffic flow elsewhere.

PHOENIX ‒ It may not be surprising to hear that coordinating the timing of city traffic signals and those at two busy Interstate 17 interchanges will save drivers time.

But the Arizona Department of Transportation and its partners, the city of Phoenix and Maricopa Association of Governments, have taken it a step further by adding up the time saved and its dollar value for a project involving Camelback and Indian School roads.

The answer: Motorists are expected to save 350,000 hours of travel time, worth $6.2 million, per year.

“Continuous improvement is ADOT’s culture and is reflected in both large and small things that the ADOT team does every day. Sometimes a seemingly small change that makes better use of resources can mean big improvements,” ADOT Director John Halikowski said. “Drivers are already seeing a time savings from this coordination. Saving time means saving money and more time with family, friends and things you enjoy doing.”

“The ADOT team’s challenge is to keep improving time savings and promote efficiency for Arizona’s taxpayers,” Halikowski added.

“When ADOT, MAG and the city of Phoenix work together strategically, the public is the beneficiary,” Phoenix Mayor Greg Stanton said. “Properly timing the traffic signals at these busy intersections will ease congestion, which gets commuters home sooner, saves fuel and keeps our air cleaner.”

A project funded by Maricopa Association of Governments’ Traffic Signal Optimization Program studied traffic signal timing at the Camelback and Indian School interchanges and nearby city streets and recommended a number of improvements. The project developed a common cycle length for all traffic signals near those interchanges and the best timing for the morning and evening commutes.

ADOT and Phoenix made these recommended changes, leading to significant improvements in travel times at these locations. An independent study by ADOT staff identified the benefits in time saved.  

Besides saving motorists time, these adjustments are expected to improve safety by reducing the number of stops drivers must make and time spent waiting at traffic lights. Shorter travel times and fewer stops also reduce fuel consumption and air pollution. 

ADOT and Phoenix continue to evaluate other I-17 corridor interchanges to see if changes in signal coordination can improve traffic flow elsewhere.

PHOENIX – As the Arizona Department of Transportation seeks to identify and fund projects that will increase capacity on Interstate 17 north of Phoenix, drivers need to do their part by avoiding the poor decisions and inattention behind so many of the crashes that result in closures and backups – and worse, injuries and fatalities.

The steep, winding stretch of I-17 between Black Canyon City and Sunset Point is one of ADOT’s priorities for improvements.

But ADOT Director John Halikowski says no widening project or highway safety measure can be as effective as drivers obeying speed limits, avoiding distractions and driving with patience. A recent analysis found that the driver violation cited in more than 40 percent of I-17 crashes in the Black Canyon City area was “speed too fast for conditions.”  

“We drive these highways too and care deeply not only about the time motorists lose in delays but the toll in injuries and lives lost due to speeding and driver inattention,” Halikowski said. “We’re committed to improving traffic flow and enhancing safety on I-17 and won’t stop until we get this done. But we can’t ignore driver behavior. We can all get home sooner and safely if we work together to avoid crashes.”

A recent safety message on ADOT’s overhead highway sign network sums up this approach: Control yourself, control your vehicle, save lives.

“Always drive defensively,” said Alberto Gutier, director of the Arizona Governor’s Office of Highway Safety. “Being constantly aware of your surroundings and the actions of other motorists is especially important in this stretch of I-17, which can see heavy traffic and demands a driver’s complete attention."

Col. Frank Milstead, director of the Arizona Department of Public Safety, said everyone in a vehicle should promote safe driving.

“Passengers, be a good co-pilot, don’t allow your driver to disregard our traffic laws and drive distracted,” Milstead said. “Encourage them to focus on safe, unselfish driving. Otherwise, they may unexpectedly meet one of our troopers during a traffic stop or collision investigation.”

ADOT will launch an I-17 safety project in 2017 focused on the area between New River Road and Sunset Point Rest Area. The project will add several electronic “speed feedback” signs with digital displays that show drivers how fast they are traveling compared to the speed limit. New signs alerting drivers to highway curves will be installed, along with four overhead message signs to inform drivers of traffic conditions.

"I-17 is vital for passenger and commercial traffic between Phoenix and northern Arizona communities," Halikowski said. "We’re determined to identify options to increase capacity in that stretch of I-17 while also working with DPS, the Governor’s Office of Highway Safety and other agencies to emphasize what drivers can do to improve safety."

PHOENIX ‒ Drivers on northbound Interstate 17 north of Camp Verde should expect to see delays through Monday (May 23) as crews complete work on the Verde River bridge.

Only one lane will be open to traffic at the Verde River Bridge between mileposts 287 and 288, just north of the State Route 260 interchange. Construction on the bridge and paving are expected to be completed by 6 p.m. Monday.

The on-ramp from SR 260 to northbound I-17 will be closed from 8 a.m. to noon on Monday.

A 12-foot width restriction will remain in place until Monday evening. Vehicles more than 12 feet wide should use SR 260 west to SR 89A, then north to Sedona, and south on SR 179 to return to I-17.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
