Crews have launched a resurfacing project on Highway 99 between 6th Street and Cabbage Lane in Phoenix to transition the corridor into a three-lane configuration. The project also includes safety upgrades to pedestrian crossings near Blue Heron Park.
Why it matters
The transition to a three-lane setup with a center turn lane significantly alters traffic flow and access points for businesses fronting the corridor. Operational planning should account for restricted curb access and potential congestion near park-adjacent crossings.
The roadwork involves a redesign of the Highway 99 corridor into a three-lane configuration. Project completion is scheduled for mid-October 2026.
The details
The current construction effort replaces existing road surfacing with a new three-lane layout that includes a dedicated center turn lane. Simultaneously, crews are implementing accessibility improvements at pedestrian crossings adjacent to Blue Heron Park to increase safety for high-foot-traffic zones. Businesses in the immediate vicinity should anticipate temporary traffic management measures until the project concludes.
Timeline
Construction was officially underway as of September 21, 2026.
The roadwork is expected to conclude on October 15, 2026.
Market Landscape
This project aligns with the traffic-calming strategies prioritized in the 2024 Phoenix Transportation Master Plan. It reflects a standard city-wide effort to balance vehicle lane efficiency with increased pedestrian safety near public parks.
Owners should notify delivery vendors of restricted access points and adjust arrival windows to account for potential congestion. Review your site's frontage to determine if the new center turn lane improves or complicates customer ingress and egress.
The takeaway
The move to a three-lane configuration signals a shift toward controlled turn access and higher pedestrian safety. Monitor traffic volume changes post-October 15 to assess the impact on your customer foot traffic patterns.
What happens next
The construction is scheduled to reach completion on October 15, 2026.
