PHOENIX - This weekend, the Arizona Department of Transportation will begin a project to repave one of the earliest sections of Interstate 17 overlaid with rubberized asphalt.

ADOT recommends drivers consider alternate routes while the I-17 work between Dunlap Avenue and Thunderbird Road occurs over the next six weekends.

The $2.6 million project consists of applying a new layer of rubberized asphalt over the existing roadway. During the next six weekends, ADOT crews will complete asphalt and bridge joint repairs between Dunlap Avenue and Thunderbird Road to give this section of the freeway a smoother, safer surface.

ADOT crews will alternate the direction of the paving work each weekend. The planned work schedule, which is subject to change due to inclement weather or other factors, is:

- Northbound I-17 will be closed between Dunlap and Thunderbird from 9 p.m. Friday, Sept. 5 to 5 a.m. Monday, Sept. 8. Northbound I-17 is also scheduled to be closed on the weekends of Sept. 19-22 and Oct. 3-6.

- Southbound I-17 will be closed between Thunderbird and Dunlap from 9 p.m. Friday, Sept. 12 to 5 a.m. Monday, Sept. 15. Southbound I-17 is also scheduled to be closed on the weekends of Sept. 26-29 and Oct. 10-13.

During each closure, I-17 traffic will be detoured along the freeway frontage roads. Drivers should also consider Loop 101 and State Route 51 to avoid the I-17 closures, in addition to 19th and 35th avenues.

After nearly 10 years of use, the one-inch overlay of rubberized asphalt along this section of I-17 is the first to have a scheduled replacement. ADOT anticipates most of the rubberized asphalt sections will last for 10 or more years, depending on traffic and roadway conditions. Older sections will continue to be evaluated for possible replacement in the coming years.

Arizona was among the first states to implement the Federal Highway Administration's Quiet Pavement Pilot Program. For every lane-mile of rubberized paving, approximately 1,500 used tires are used, keeping them out of landfills. Because rubberized asphalt cannot be applied during cold or extremely hot weather, paving with it in the Phoenix area must be done in the fall and spring-roughly between Sept. 1 and Nov. 15 and from March 15 to May 31 each year.

This project is part of the Regional Transportation Plan approved by Maricopa County voters in 2004. Under the plan, a variety of transportation improvements in the Phoenix area, including new and expanded freeways, transit facilities and local street upgrades, are being constructed through 2025.
