Improvement projects will require closing roads and restricting lanes along several Valley freeways this weekend.

State transportation officials said drivers should prepare for delays and detours from Friday night, Sept. 6, until Monday morning, Sept. 9:

• Northbound I-17 will be closed at Jomax Road and narrowed to one lane between Jomax Road and Loop 303/Sonoran Desert Drive from 10 p.m. Friday to 5 a.m. Monday for pavement improvements.

Jomax Road will be closed in both directions at I-17. Primary Detour: Northbound I-17 traffic will use the off- and on-ramps at Jomax Road. Detour recommendation: Use the primary detour rather than local roads, which aren’t designed for heavy traffic.

• Westbound I-10 will be closed between US 60 and the I-17 “Split” interchange near Sky Harbor Airport from 10 p.m. Friday to 4 a.m. Monday for construction.

 Westbound I-10 on-ramps at Elliot and Baseline roads plus the westbound US 60 on-ramps at McClintock Drive, Rural Road and Mill Avenue will be closed (ramp closures start at 8 p.m. Friday). Westbound US 60 will be narrowed to three lanes between Mill Avenue and I-10. The southbound SR 143 on-ramp at University Drive will be closed. Detour: Westbound I-10 drivers can consider using eastbound Loop 202 or eastbound US 60 to northbound Loop 101 and westbound Loop 202 in the Tempe area. Another alternate route is westbound/northbound Loop 202 to reach I-10 in west Phoenix. Note: 32nd Street will be closed in both directions between Wood and Elwood streets near I-10 from 8 p.m. Friday to 4 a.m. Monday. Detours will be in place.

• Westbound Loop 202 will be closed between Williams Field Road and Gilbert Road from 10 p.m. Friday to 5 a.m. Monday for a widening project. 

The westbound Loop 202 on-ramp at Higley Road will be closed. Detours: Consider exiting ahead of the closure and using alternate routes, including southbound Higley Road to westbound Germann Road or westbound Williams Field Road to southbound Gilbert Road.

• Eastbound US 60 narrowed to three lanes (right lanes closed) between Dobson and Gilbert roads from 9 p.m. Friday to 5 a.m. Monday for pavement maintenance. 

Eastbound US 60 on- and off-ramps between Dobson and Gilbert roads will be closed. Detour: Consider exiting ahead of the work zone while ramps are closed and using eastbound Baseline Road or Southern Avenue as alternate routes.

• Southbound State Route 51 ramp to eastbound Loop 202 and westbound I-10 will be closed from 9 p.m. Friday to 5 p.m. Sunday for bridge maintenance.

 Detours: Consider exiting ahead of the ramp closure and using local streets to connect with eastbound Loop 202 or westbound I-10. Southbound SR 51 drivers also can detour to eastbound I-10 and exit at Washington/Jefferson streets before making left turns at the interchange to connect with eastbound Loop 202 or westbound I-10.

• Frank Lloyd Wright Boulevard will be closed in both directions at Loop 101 from 9 p.m. Friday to 5 a.m. Monday for lane striping.

Frank Lloyd Wright Boulevard traffic will not be able to cross under the freeway. Detours: Traffic can use the frontage roads and nearby cross streets (Raintree Drive for southbound traffic and Bell Road for northbound traffic) to travel around the closure.
