PHOENIX – Improvement projects will require closures along sections of some Phoenix-area freeways this weekend (Feb. 28-March 3), according to the Arizona Department of Transportation. That includes a closure of southbound Interstate 17 near State Route 74 in north Phoenix. Drivers should allow extra travel time and plan on using detour routes while the following weekend restrictions are in place:

• Southbound I-17 closed between State Route 74/Carefree Highway and Loop 303 in north Phoenix from 10 p.m. Friday to 5 a.m. Monday (March 3) for pavement improvement project. Southbound I-17 on-ramps at SR 74 and Dove Valley Road closed. Allow extra time and consider adjusting travel schedules (traffic is lighter during early morning or late night). Detour: Southbound I-17 traffic will travel west on SR 74 to southbound Lake Pleasant Parkway and use eastbound Loop 303 to return to I-17. Avoid using neighborhood streets adjacent to I-17 that are not designed to handle freeway traffic. Drivers should stay with the designated SR 74 detour route. Some street closures will be in place (local traffic only).
• Northbound Loop 101 (Pima Freeway) closed between Shea Boulevard and Princess Drive/Pima Road in north Scottsdale from 10 p.m. Friday to 5 a.m. Monday (March 3) for bridge work as part of widening project. Northbound Loop 101 on-ramps at Via de Ventura and 90th Street closed. Consider alternate freeway routes to avoid delays. DETOUR: Traffic exiting at Shea Boulevard can travel west to northbound Scottsdale Road to reach Loop 101 north of Bell Road.
• Eastbound Loop 101 (Agua Fria Freeway) closed between 35th Avenue and I-17 from 10 p.m. Friday to 5 a.m. Monday (March 3) for sign structure removal as part of widening project. Detour: Traffic exiting at 35th Avenue can travel north or south to reach cross streets that connect with I-17 (examples: Deer Valley Road for northbound or Union Hills Drive for southbound). Note: The north- and southbound I-17 ramps to eastbound Loop 101 will remain open.
• Northbound SR 143 (Hohokam Expressway) closed between I-10 and Loop 202 (Red Mountain Freeway) near Sky Harbor Airport from 7 p.m. Saturday to 4 a.m. Monday (March 3) for pavement marking work.

Travelers going to Sky Harbor Airport can use routes to the airport’s west entrance (via Buckeye Road). Note: Eastbound I-10 on-ramp at Warner Road closed from 8 p.m. Friday to 5 a.m. Sunday (March 2) for construction. Consider using the eastbound on-ramp at Ray Road.

Schedules are subject to change due to inclement weather or other factors. ADOT plans and constructs new freeways, additional lanes and other improvements in the Phoenix area as part of the Regional Transportation Plan for the Maricopa County region. 

Most projects are currently funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004. Voters in November approved Proposition 479, extending the existing half-cent tax to fund future transportation projects in the Phoenix region.

Real-time highway conditions are available on ADOT’s Arizona Traveler Information site at az511.gov, the az511 app (download for Apple or Android devices) or by calling 511.
