The Arizona Department of Transportation (ADOT) has announced that westbound Interstate 10 will be closed between US 60 and I-17 from 10 p.m. yesterday, until 4 a.m. on Monday, October 21. This closure is necessary to complete pavement marking and sign installation as part of a larger road improvement project. Drivers heading west will face detours and ramp closures, including from westbound US 60 to westbound I-10 and from southbound State Route 143 to westbound I-10, with additional on-ramp closures beginning at 8 p.m. yesterday. For detailed detour information, ADOT advises visiting their website, where alternative routes like eastbound Loop 202 or northbound Loop 101 are suggested to bypass the affected areas.
ADOT has provided alternative routes for drivers, directing them to use the Loop 202—both the Santan and Red Mountain Freeways—and the northern section of Loop 101 to bypass the closures. For those heading to Phoenix Sky Harbor International Airport, there's a designated detour via northbound Loop 101 to westbound Loop 202, allowing easy access to Sky Harbor Boulevard. However, ADOT cautions that these plans may change due to Arizona's weather or unforeseen events, and they encourage motorists to stay informed through TheCurve mobile app or by visiting i10broadwaycurve.com/alerts/ for the latest updates.
The weekend's closures and detours are part of the broader I-10 Broadway Curve Improvement Project, funded by the half-cent sales tax approved by Maricopa County voters through Proposition 400 in 2004. As outlined by the Maricopa Association of Governments in the Regional Transportation Plan, the project's goal extends beyond simply improving traffic flow and airport access; it aims to prepare the region's infrastructure for future growth by enhancing carpooling options and meeting the increasing demands of transit systems. More information about the project is available on ADOT's website.
