SR 87, SR 260 and SR 179 Roadway Departure Safety Project

SR 87, SR 260 and SR 179 Roadway Departure Safety Project


This project is complete


Project Cost: $4,460,000

Project Overview

The Arizona Department of Transportation, in partnership with the Federal Highway Safety Improvement Program, has initiated a safety project to establish roadway departure zones along portions of State Route 87 (mileposts 247-251, 283-316), State Route 260 (milepost 240-252) and State Route 179 (milepost 299-305).

A roadway departure zone is an unobstructed roadside area - adjacent to the roadway - that provides drivers who leave the road in a crash incident adequate distance to stop or regain control of their vehicles. The project, which will also increase driver visibility along the corridor, will enhance safety to both drivers and their passengers.

Due to existing trees, shrubs and other vegetation along these highways, the existing roadway departure zones do not meet state or federal standards. As a result, ADOT needs to remove the vegetation to re-establish the departure zone.

As part of the project, crews will remove vegetation - including trees, shrubs, logs and upturned stumps - that present a hazard to drivers on both sides of these roadways. The roadway departure zone clearance areas will be 5 feet behind guardrails (where guardrail exists) and 30 feet in all other locations.

The work will be completed within ADOT’s right of way. The project also includes seeding, pruning, chipping, cutting, hauling and stockpiling usable firewood. US Forest Service is taking ownership of all merchantable and firewood from the project.

What to expect during construction

The work will occur during daytime hours, Mondays through Fridays. No work is planned during weekends or holidays. One lane of traffic will remain open at all times, and existing turn lanes will also stay open. Barricades or other traffic-control devices will be removed after crews finish working each day.

ADOT reminds drivers to proceed through the work zone with caution, slow down and watch for construction personnel and equipment.


Project schedule

The project is expected to begin summer 2023 with anticipated completion in winter 2023. The schedule is subject to change based on weather or other unforeseen factors.
