The Arizona Department of Transportation will begin work on the Lakeview Drive intersection on Monday, Nov. 27 as part of the John Wayne Parkway (State Route 347) Improvement project in Maricopa. ADOT advises drivers to plan for the following restrictions:

  • Westbound Lakeview Drive, the exit to the Rancho El Dorado community, will be restricted to one lane between Rancho El Dorado Parkway and John Wayne Parkway beginning 8 a.m. Monday, Nov. 27, through mid-spring.
    • Westbound drivers will not be able to make a left turn onto John Wayne Parkway or travel through the intersection; traffic will only be able to make a right turn.
    • DETOUR: Drivers can take Rancho El Dorado Parkway to Vintage Drive, then westbound Smith Enke Road to SR 347. 

ADOT advises drivers to slow down and use caution around construction personnel and equipment while work is underway.

Interim Improvements: SR 347, I-10 to Northern Maricopa Limits 2023 Road Safety Assessment

Interim Improvements: SR 347, I-10 to Northern Maricopa Limits 2023 Road Safety Assessment



As the primary route from the city of Maricopa to the Phoenix area, State Route 347 (SR 347) has become a highly traveled corridor. In spring 2023, ADOT completed a safety study on SR 347 between I-10 and the northern city limits of Maricopa. The Road Safety Assessment (RSA) identified potential safety issues related to roadway traffic and evaluated possible ways to improve safety for drivers.

As a result of this assessment, the following are being implemented as interim measures to improve traffic conditions until more long-term improvements can be made.

Project Fact Sheet:


What: Restriping in the following areas to add or extend turn lanes: Queen Creek Road/Interstate 10 interchange; Riggs Road intersection; Casa Blanca Road intersection; Old Maricopa Road intersection; and the Mammoth Way intersection.

Why: Restriping will allow for more vehicles to queue in the turn lanes and potentially alleviate some of the congestion and back-ups at these intersections. 

When: These changes were implemented in October 2023.

What: New traffic signs added or replaced at intersections. There will also be an additional signal pole installed at the eastbound I-10/Queen Creek off-ramp. Traffic signal timing has been adjusted, and will continue to be monitored and adjusted as needed in the future. Reflective signal head backplates will also be installed.

Why: The new signs and existing sign changes will provide additional guidance for lane usage and improve both driver awareness and line of sight at intersections. The new signal pole (I-10/Queen Creek Road) is an additional signal head that will improve the signal timing and better manage the traffic coming off the freeway. The signal timing adjustments will help alleviate unnecessary stopping of traffic at certain intersections. The reflective backplates on signals improve visibility in both daylight and darkness. 

When: The reflective backplates were installed in October 2023. Some of the signs and signals require environmental clearance and are estimated to take 4-6 months.

Emergency Signal Ahead Signs:
The implementation of flashing ‘Signal Ahead’ warning signs and beacons at certain intersections is still under review.  These devices are intended to reinforce awareness of existing traffic signals and can be placed in advance of signalized intersections where the intersection is hidden from the view of approaching travelers. If deemed appropriate, installation will also require environmental clearance.


What: Four existing median crossovers refreshed as needed to allow access for emergency vehicle use. One additional median crossover will be created for an additional access point in the corridor. These locations are: milepost (MP) 177.81, MP 179.22, MP 184.24 and MP 188.62; and a new crossover at MP 185.77.

Why: These improvements will allow for better access for first responders throughout the corridor in the event of an accident. 

When: The work for the median crossovers required environmental clearance and is expected to be completed in January 2024. 


What: Removal of signs that currently reduce the speed limit from 65 mph to 55 mph approaching intersections. 

Why: This change is intended to increase compliance, reduce differential speeds, reduce the need for lane changing and potentially reduce rear-end crashes. 

When: New signs were installed in October 2023.
