US 89 Drainage Improvements
Contents
Overview
Project cost: $17 million
The Arizona Department of Transportation has initiated a drainage infrastructure project along US 89 six miles north of Flagstaff (mileposts 423-432). The project is expected to be under construction in spring 2025 and anticipated for completion in late 2025.
The purpose of the project is to address damage and improve the function of existing drainage infrastructure that sustained damage during the 2022 monsoon season.
Project Elements
Project elements include:
- Remove existing shotcrete flood control channels and reconstruct new concrete channels, as needed.
- Repair spillways and down drains, as needed.
- Construct concrete box culvert improvements.
- Remove and replace pavement, as needed.
- Construct temporary median crossovers for culvert construction.
- Remove and apply roadway striping, as needed.
- Trim and/or remove vegetation.
- Seed disturbed areas with native plant species, as needed.
What to Expect
While drainage work is underway, 24-hour lane restrictions will be in place to allow crews to reconstruct the existing drainage channels Mondays through Saturdays.
A minimum of one lane in each direction will remain open during construction. ADOT advises drivers to plan for possible delays while the work is underway.
