As part of the project to create a new interchange at I-17, a stretch of Pinnacle Peak Road just east of the interstate is scheduled to close in both directions for 23 days starting Tuesday, Feb. 19. The closure is expected to be in place until Thursday morning, March 14. Crews will replace a large drainage culvert.
Expect heavy traffic and delays, ADOT said in a statement today. Detour information from the agency:
- Drivers who use eastbound Pinnacle Peak Road to cross I-17 from west to east or to access 19th Avenue can use southbound 35th Avenue to eastbound Deer Valley Road to 19th Avenue. Drivers can then use northbound 19th Avenue to reach Pinnacle Peak Road east of I-17.
- Drivers from locations north of Happy Valley Road who must access Pinnacle Peak Road west of I-17 can use southbound 19th Avenue to westbound Happy Valley Road.
- Drivers from locations between Pinnacle Peak and Happy Valley roads who must access Pinnacle Peak Road west of I-17 can use southbound 19th Avenue to westbound Deer Valley Road.
- Drivers exiting the area north of Williams Drive and the Metro Phoenix RV Park can use the northbound frontage road to Pinnacle Peak Road and turn west to access Pinnacle Peak Road west of I-17 or continue north on I-17 and exit at Happy Valley Road.
Businesses and schools located south of Pinnacle Peak Road between I-17 and 23rd Avenue will be accessible from 19th Avenue, ADOT said.
The $50 million I-17 project, detailed last summer and slated for completion in fall 2020, will replace the interchange at Happy Valley Road, too, and add a new lane in each direction on I-17. Find more about the overall project, along with any planned I-17 lane closures, here.
