The completed Broadway Curve Improvement Project enhancing traffic safety and flow.

News Summary

The Arizona Department of Transportation has announced the completion of the Broadway Curve Improvement Project, the largest urban freeway reconstruction in state history. The $833 million project enhances an 11-mile stretch of Interstate 10, improving safety and traffic flow for over 300,000 daily motorists. Key features include wider lanes, new bridges, and sound walls. While major construction has finished, some cosmetic work continues, and the area is set to accommodate future traffic demands as the region grows.

Arizona has successfully completed the Broadway Curve Improvement Project, as announced by the Arizona Department of Transportation (ADOT) on June 3. This significant infrastructure undertaking represents the largest urban freeway reconstruction in the state’s history, with a total cost of approximately $833 million.

The Broadway Curve project encompasses an 11-mile stretch of Interstate 10 (I-10), extending from Loop 202 to I-17 near Phoenix Sky Harbor International Airport. This vital roadway serves over 300,000 motorists on a daily basis, with estimates suggesting that this figure could rise to 375,000 by 2040 as the region continues to grow.

The completion of the project signifies the end of four years of significant construction chaos, which included a series of weekend closures and delays for commuters and residents in the area. Construction for this expansive improvement began on July 23, 2021, following recommendations made by a Maricopa Association of Governments study conducted from 2014 to 2017, which highlighted the urgent need for upgrades along this corridor.

Project Highlights

The Broadway Curve Improvement Project introduced several important features aimed at enhancing both traffic flow and safety for motorists. Key upgrades include:

New, wider lanes designed to better accommodate current and future traffic needs.
New bridges that improve connectivity and reduce travel times.
Sound walls to minimize noise pollution for nearby communities.

Additionally, the project included enhancements to one mile of U.S. 60 and one mile of State Route 143 to create a more efficient traffic distribution system that collects vehicles from these routes and directs them to connecting highways and local roads.

Post-Construction Developments

While major construction activities have concluded, some finishing touches such as landscaping and cosmetic work are still in progress. The redesigned roadways now have a speed limit of 55 mph, lower than the typical 65 mph limit for freeways, aimed at promoting safer driving conditions.

Funding and Future Benefits

The funding for this extensive project was sourced from a half-cent sales tax that was approved in Maricopa County back in 2004 through Proposition 400. This state funding was further supplemented by resources from the Federal Highway Administration.

The improvements brought by the Broadway Curve project are anticipated to facilitate increased accessibility for residents, allowing for easier commutes for work, school, and daily activities. Furthermore, the project is expected to reduce travel times during peak rush hours and support ridesharing and public transit options across the region.

Implications for Growth

As the metropolitan area grows, the Broadway Curve project aims to accommodate the anticipated increase in traffic demands, ensuring that the infrastructure keeps pace with population growth and economic development. The completion of this project lays a strong foundation for future developments in transportation and accessibility throughout the Phoenix area.

In conclusion, the successful completion of the Broadway Curve Improvement Project marks a significant milestone in Arizona’s transportation infrastructure and signals a commitment to improving roadways while addressing the future needs of its residents.
