PHOENIX – Readers: The start time for this weekend's closure of westbound Loop 303 is 8 p.m. Friday (Oct. 28). Improvement projects on several Phoenix-area freeways will require closures or lane restrictions this weekend (Oct. 28-31), according to the Arizona Department of Transportation. Drivers should allow extra time and plan alternate routes. The following freeway restrictions are scheduled this weekend along Phoenix-area freeways:

• Eastbound I-10 closed between State Route 51 and US 60 (Superstition Freeway) near Sky Harbor Airport from 10 p.m. Friday to 4 a.m. Monday (Oct. 31) for the I-10 Broadway Curve Improvement Project. All eastbound on-ramps between Third St and Broadway Road, including the southbound SR 51, westbound Loop 202, southbound I-17 and southbound SR 143 ramps to eastbound I-10, will be closed. Southbound I-17 on-ramps at Seventh Avenue and Seventh Street closed. Detour: Allow extra travel time. Eastbound I-10 traffic north of downtown Phoenix can detour on eastbound Loop 202 (Red Mountain Freeway) and use southbound Loop 101 (Price Freeway) and westbound US 60 in Tempe to reconnect with I-10 beyond the closure. I-10 drivers in the West Valley also can consider using southbound/eastbound Loop 202 (South Mountain Freeway) to avoid the closure and reach I-10 south of Chandler Boulevard.

Northbound I-17 on-ramps at Bethany Home Road and Glendale Avenue also closed. Detours: Allow extra travel time. Consider using northbound SR 51 to westbound Loop 101 (Pima Freeway) in north Phoenix to reach northbound I-17. Drivers on northbound I-17 can consider exiting ahead of the closure and using northbound 19th or 35th avenues to travel beyond the closure.

Detour: Consider exiting northbound Loop 101 ahead of the closure and using alternate routes. Drivers exiting at Frank Lloyd Wright Boulevard can travel west and continue on Bell Road to northbound SR 51 to enter westbound Loop 101 beyond the closure. Drivers north of Loop 101 can consider using westbound Pinnacle Peak Road to southbound Cave Creek Road. An alternate freeway route from the East Valley is westbound Loop 202 (Red Mountain Freeway) to northbound SR 51 to reach Loop 101. Note: One northbound Loop 101 lane between Frank Lloyd Wright Boulevard and the Pima Road exit will remain open. Expect delays and consider alternate routes.

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. Projects are funded in part by Proposition 400, a dedicated sales tax approved by Maricopa County voters in 2004.
