State Route 85 Intersection Improvements in Buckeye

Overview

The Arizona Department of Transportation, in coordination with the City of Buckeye and Maricopa County, is in the design phase for three intersection improvements projects along State Route 85.

The design and improvements are based on the Final Feasibility Study (dated June 2025), which was prepared by the Maricopa Association of Governments (MAG).

The improvements consist of reconstructing the intersections of SR 85 with Broadway Road, Southern Avenue and Baseline Road.

• Incorporating a raised center median
• Widening SR 85 to provide an additional left-turn lane and extending existing turn lanes along north- and southbound SR 85
• Level the ground for new pavement
• Removing existing asphalt and replacing with new asphaltic concrete pavement
• Installing traffic signal poles and control cabinets
• Installing conduit to support the new traffic signals
• Installing new striping and pavement markings
• Installing roadway lighting
• Constructing new sidewalks, curb and gutter, and pedestrian ramp features, as needed, to meet Americans with Disabilities Act (ADA) guidelines
• Removing, replacing, and installing new signage
• Conducting geotechnical activities including potholing to locate utilities and relocating utilities, as needed
• Installing drainage improvements and erosion control protection
• Seeding disturbed areas with native plant species, as needed

Project Schedule
