PHOENIX – During this upcoming weekend’s full closure of Interstate 10 between State Route 51 and SR 143, Salt River Project (SRP) crews will safely move a utility pole fondly referred to as the “North Pole.” The massive 75-foot-tall pole on the north side of I-10 near 46th Street needs to shift 102 feet further north to make way for improvements on I-10 as part of the  I-10 Broadway Curve Improvement Project . 

In its current location, the North Pole, which weighs about 34,000 pounds, stands in the way of the new southbound SR 143 to westbound I-10 ramp and Collector-Distributor roads that will improve traffic flow on this busy section of I-10. Over the weekend SRP will begin transferring the 69kV conductor to the new pole and remove and replace the 12kV conductor (and SRP Communication line). All attachments will be made to the new pole and the old pole will be removed.

While SRP crews have the closure in place this weekend from 10 p.m. Friday, April 22, to 4 a.m. Monday, April 25, Broadway Curve Constructors will take advantage of the opportunity to repair the pavement driving surface and shift the project work zone. 

Learn more about this weekend’s major highway closure and speak with representatives from SRP and the Arizona Department of Transportation (ADOT) at the “North Pole” this Friday, April 22, 2022.

Interstate 10 closed in both directions between SR 51 and SR 143 the weekend of April 22-April 25

April 25, 2022

PHOENIX –The Arizona Department of Transportation advises motorists to expect delays and allow plenty of extra travel time while Interstate 10 is closed to east and westbound travel  between SR 51 and SR 143 the weekend of April 22-April 25 to accommodate work related to the I-10 Broadway Curve Improvement Project. 

The closure is scheduled from 10 p.m. Friday, April 22, through 4 a.m., Monday, April 25. Motorists should plan ahead for detours along the state highway system and anticipate travel delays.

Salt River Project crews are relocating a large overhead power line that currently stands in the way of widening I-10 in conjunction with the I-10 Broadway Curve Improvement Project. While SRP’s closure is in place, Broadway Curve Constructors (BCC) will take advantage of the opportunity to shift the work zone on I-10 and make repairs to the freeway’s pavement. By combining this work with the SRP closure, BCC can eliminate the need for a separate highway closure, as well as further inconvenience for the traveling public. 

Here’s what to expect:

• Eastbound I-10 will be closed between SR 51 and SR 143. The eastbound I-10 on-ramps between Third and 40th streets; the southbound I-17 on-ramps at Seventh Avenue and Seventh Street; the westbound Loop 202 (Red Mountain Freeway) ramp to eastbound I-10; the southbound SR 51 on-ramp at McDowell Road and the ramp from southbound SR 51 to eastbound I-10 will be closed.
• Westbound I-10 will be closed between SR 143 and I-17. The westbound I-10 on-ramps between Elliot Road and 32nd Street, the westbound US 60 (Superstition Freeway) on-ramp at Mill Avenue and the westbound US 60 ramp to westbound I-10 will be closed.

Eastbound I-10 Detour: Continue east on the Loop 202 (Red Mountain Freeway) to southbound Loop 101 (Price Freeway) and westbound Loop 202 (Santan Freeway) to  access eastbound I-10. Drivers traveling on southbound I-17 can use westbound I-10 to eastbound Loop 202 (Drivers should avoid westbound US 60 west of Loop 101 in Tempe due to lane restrictions.)

Westbound I-10 Detour: Exit onto eastbound US 60 before traveling north on Loop 101  to westbound Loop 202 in order to access westbound I-10. (Drivers can also use eastbound and westbound Loop 202 (Santan/South Mountain Freeway) as alternate detour routes.)

Motorists heading to the West Valley: Bypass the closure by using west- and northbound  Loop 202 (South Mountain Freeway) and connecting with I-10 at 59th Avenue.

Phoenix Sky Harbor International Airport traffic: Allow extra travel time and use the east entrances from Loop 202 and SR 143.

PHOENIX – Motorists who drive over the 55 mph speed limit while traveling through the Arizona Department of Transportation’s largest-ever urban freeway reconstruction project could end up getting a ticket as ADOT increases its efforts to encourage motorists to slow down in the project work zone. 

In the Phoenix-metro area, the Interstate 10 Broadway Curve Improvement Project stretches for 11 miles from the Loop 202 Santan/South Mountain Freeway interchange to I-17 near Phoenix Sky Harbor International Airport. The ADOT project team is initiating a campaign to raise awareness of work zone safety that includes added Department of Public Safety patrols in the area.

“The I-10 Broadway Curve Improvement Project is one of the most visible work zones in the state, but speeding through any work zone can be deadly and costly for drivers, their passengers and of course workers in these zones,” said Project Manager Amy Ritz. 

She added, “One aspect of this project that has taken me by surprise is the number of people who risk their lives, and the lives of others every day, to save about three minutes. That’s how much time you save if you drive these 11 miles at 75 mph compared to the posted 55 mph limit. The time it takes to listen to a hit song is not worth someone’s life.”

In addition to the added enforcement, ADOT is using overhead message signs and billboards to share safety information and has produced a public service announcement  featuring I-10 Broadway Curve project team members asking drivers to slow down. 

Whether a work zone is a major construction project or a one-day repair and maintenance job, drivers should expect the unexpected, always obey speed limits, never drive distracted or impaired, and be especially vigilant and patient.

What takes 11 hours to empty, weighs just over 2,000 tons and can cover a football field half a foot deep? It's the 1,000 cubic yards of concrete that was poured over the weekend in conjunction with the Arizona Department of Transportation's Interstate 10 Broadway Curve Improvement Project.

On Saturday, I-10 Broadway Curve Improvement Project crews completed a critical step for the foundation that will support the new Broadway Road bridge that is being constructed over I-10. They poured 1,000 cubic yards of concrete to create what is called a “bridge footing.” This footing is a large concrete slab that will play an important role in the support and distribution of weight for the new bridge. 

The new bridge over I-10 is one of several bridges being replaced or widened as part of the I-10 Broadway Curve Improvement Project. Crews will take down the existing Broadway Road bridge after the new one is completed later on in the project.

PHOENIX – Months before construction begins on reconstruction of Interstate 10 through the Broadway Curve, the Arizona Department of Transportation is identifying native plants to preserve along an 11-mile section of the freeway.

Crews are examining an estimated 2,500 trees along I-10 between Interstate 17 and the Loop 202 (Santan/South Mountain Freeway) to identify state-protected plants -- such as ocotillo and saguaro and barrel cactus -- and native trees, including palo verde, mesquite and ironwood. Plants will be relocated into temporary nurseries during construction so they can be transplanted when work is complete.

“Protecting the natural Arizona environment is an important part of our work,” said Robert Samour, senior deputy state engineer and leader of ADOT’s Major Projects Group. “There were more than 1,000 plants along the South Mountain Freeway that we maintained for more than three years and replanted after construction to preserve the plants and the beautiful landscape.”

Crews will remove plants near I-10 to clear the way for construction of new freeway lanes and other improvements.

ADOT anticipates construction will begin this summer on the Valley’s first urban freeway reconstruction project. Over the next several months, crews will relocate utility lines and continue design work as preparations continue on one of the largest freeway construction projects in Arizona history. ADOT anticipates construction will be complete by late 2024.

In January, ADOT signed a $615.6 million contract with a joint venture of Pulice Construction, FNF Construction and Flatiron Constructors to design and construct the project, with T.Y. Lin International Group as the lead designer. The improvements will enhance safety, reduce travel time, ease access to Phoenix Sky Harbor International Airport and support the local, regional and state economies.

Improvements include:

• Widening I-10 to six general purpose lanes and two HOV lanes between 24th Street and US 60 (Superstition Freeway).
• Building collector-distributor roads between Baseline Road and 40th Street to separate local traffic from through traffic on I-10. 
• Adding an additional general purpose lane on I-10 from US 60 to Ray Road and keeping the HOV lane.
• Modifying I-10 connections at State Route 143, Broadway Road and US 60 to improve traffic flow and safety.
• Adding two bridges for pedestrians and bicyclists over I-10 between Baseline and Broadway roads and improving the Sun Circle Trail crossing at Guadalupe Road.

The I-10 Broadway Curve improvement project is funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004.
