The Loop 101 Improvement Project between Shea Boulevard and Loop 202 (Red Mountain Freeway) recently marked a key milestone with the completion of a new pavement overlay along the freeway’s southbound lanes. The new one-inch top layer of rubberized asphalt was needed before the project team could open the new right lanes along the southbound Pima Freeway.
Weather conditions do provide a challenge for paving crews. Rubberized asphalt, which includes a mixture of rubber from recycled tire and heated liquid asphalt, requires a favorable temperature range for the best results when it is being added along a freeway. Paving schedules were adjusted at times this spring due to weather that was either too cool, too hot or too wet.
Specialized work to lift a portion of northbound pavement that had dipped over time near McDonald Drive, due to ground settlement beneath the freeway, is scheduled to wrap up later this month. Crews have been working at night to inject an expansion foam beneath the northbound lanes. As the foam expands it also hardens, stabilizing the soil while also lifting the freeway pavement.
Rubberized asphalt paving along the northbound lanes is due to resume on weekends when favorable weather conditions are in place. ADOT will continue to keep motorists up to date on scheduled closures or restrictions via news releases, emailed project updates as well as messages on signs along freeways in the region. The entire project is slated for completion by fall 2016.
Information about the project is available at azdot.gov/Loop101.
ADOT will provide advance notification of full closures or significant restrictions that affect drivers or the community, as well as information about detour routes. For detailed information on weekly construction-related closures and restrictions, check the Traffic Alerts page.
ADOT's two and one-half year construction project that began in summer 2014 will widen the Loop 101 from Shea Boulevard to the Loop 202 (Red Mountain Freeway) interchange. Once completed the project will include these features:
- An additional travel lane southbound from Shea Boulevard to McKellips Road
- An additional travel lane northbound from McDowell Road to Shea Boulevard
- Two additional travel lanes from the northbound Loop 101 / Loop 202 interchange entrance ramp to McDowell Road
- Chaparral Road traffic-interchange improvements
- A quieter and smoother driving experience due to the use of rubberized asphalt on the widened roadway surface
