Southern Avenue and Meridian Road Widening

YSMA designed drainage and roadway improvements at Meridian Road in the vicinity of Southern Avenue due to flooding during storm events, which rendered the intersection inoperable.

  • Aligned through lanes on Southern Avenue, which improved a previous 12 foot shift in alignment through the intersection.

  • Designed improvements to avoid relocation of gravity-fed sewer line and overhead power poles, as well as accommodated over 600 cfs runoff.

  • Garnered stakeholder support as project boundaries included Maricopa County, City of Mesa, Pinal County, and Apache Junction.
