Project Cost: $3.7 million

The Arizona Department of Transportation has initiated a guardrail replacement project along State Route 89A in Oak Creek Canyon between Pine Flat Campground and Oak Creek Vista. The project, which is approximately 13 miles north of Sedona (mileposts 387-390), is expected to be under construction in spring 2026 and anticipated for completion by fall 2026.

A major component of the work will be building the direct ramps to create the freeway-to-freeway interchange. When completed over the next two-and-a-half years, drivers will skip the traffic signals at the current Loop 303/I-17 diamond interchange.
