The Arizona Department of Transportation’s recently announced 2026-2030 Five-Year Transportation Facilities Construction Program includes a significant focus on “Greater Arizona”—regions outside the state’s major metro areas—and pavement preservation to extend investments made in Arizona roadways.
La Paz and Mohave counties will both see prominent expansions in projects and funding, including more than $200M targeted toward highways, bridges and border facilities.
ADOT’s La Paz and Mohave priorities will focus on aging infrastructure, border access, repairing weather damage and addressing modernization needs.
La Paz County Projects
Two major projects are planned in La Paz.
The first is California Border to Dome Rock Road (milepost 0 to 11), which is planned for 2027 at a cost of $48.3M and will address traffic volumes and pavement rehabilitation.
Also budgeted for 2027, the second La Paz project is a $5M rockfall mitigation effort in the Parker Dam Area (milepost 158 to 161.1).
