Weekend closures of parts of Loop 202 (Santan Freeway) set for May

PHOENIX – Sections of Loop 202 (Santan Freeway) in the southeast Valley are scheduled to be closed on two weekends in May for pavement improvements.

The Arizona Department of Transportation has set the following closures to allow crews to apply an asphalt-based treatment to extend the life of the existing pavement and also repair areas of worn pavement:

• Loop 202 closed in both directions between US 60 (Superstition Freeway) in Mesa and Williams Field Road in Gilbert from 10 p.m. Friday (May 3) to 3 a.m. Monday (May 6) for pavement improvements. Both US 60 ramps to southbound Loop 202 closed. Please plan ahead and be prepared to use alternate routes, including US 60 and Loop 101 to reach Loop 202 in the Chandler area.
• Loop 202 closed in both directions between Loop 101 (Price Freeway) in Chandler and Williams Field Road in Gilbert from 10 p.m. Friday (May 10) to 3 a.m. Monday (May 13) for pavement improvements. Southbound Loop 101 ramp to eastbound Loop 202 in Chandler closed. Please plan ahead and be prepared to use alternate routes, including US 60 (Superstition Freeway).

Following a wet winter, ADOT crews have been working since February to make repairs, often during overnight hours, to areas of freeway pavement damaged by a combination of moisture and heavy traffic.

The fog seal treatment along the Santan Freeway in the southeast Valley will involve tanker trucks spraying an asphalt-based emulsion on the pavement. Crews will be prepared to reopen the freeway in segments after the emulsion has time to dry and other pavement repairs are completed. The treatment helps offset the effects of aging and drying in older pavement, including rubberized asphalt, extending its life cycle.

Fog seals have been applied with positive results in recent years along sections of other Valley freeways, including I-10, Loop 101 and Loop 303 in the West Valley and State Route 51 in Phoenix.
