Project cost: $21 million

Overview

The Arizona Department of Transportation has initiated a wildlife overpass and fence installation project along Interstate 17 between Kelly Canyon and Munds Park (mileposts 322-331) south of Flagstaff. The Willard Springs Wildlife Overpass and other improvements will be located at milepost 327. The project is expected to be under construction in spring 2025 and anticipated for completion by fall 2026.

ADOT, in partnership with Arizona Game and Fish, sought a $24 million grant through the Federal Highway Administration's (FHWA) Wildlife Crossings Pilot Program to reduce motor-vehicle crashes involving wildlife and better connect habitats along I-17 south of Flagstaff. The I-17 wildlife project is one of 19 nationally to receive funding through the first round of $110 million in grants from FHWA.

Overview

Project cost: $6.9 million

The Arizona Department of Transportation, in cooperation with the city of Flagstaff, initiated a project to construct a new roundabout that will replace the signalized intersection at Fourth Street and Cedar Avenue/Lockett Road to improve the safety and function of the intersection. This new roundabout will be designed with flashing pedestrian crossing beacons and will slow speeds, help avoid angle collisions and add a crosswalk at the fourth-leg of the intersection. Additional work includes the installation of water, sewer and storm drain infrastructure. 

Preliminary construction activities are set to begin on early spring 2025.

Preliminary work consists of tree removal, fence installation, concrete removal and storm drain installation along the perimeter of the intersection. A full closure of the Fourth Street and Cedar Avenue/Lockett Road intersection is scheduled for the entire 2025 school summer break (May 23 to Aug. 4), with the full project anticipated to be complete in fall 2025. The new roundabout will be installed during this full closure.

Overview

The Arizona Department of Transportation has initiated a project to install more than 200 miles of high-speed fiber-optic infrastructure along Interstate 40 between the Arizona-California state line and Flagstaff (mileposts 0-201).

Purpose

The purpose of this project is to install high-speed fiber-optic conduit along the entire project corridor to eventually expand broadband internet access to homes and businesses in rural parts of the state.

In addition to rural broadband connectivity, ADOT plans to use the fiber-optic conduit to provide intelligent transportation system (ITS) technology, such as overhead message boards, traffic cameras, weather stations and other uses. The infrastructure will also help lay the groundwork for emerging automotive technologies, such as connected and automated vehicles.

Project Area Map

Once the fiber-optic conduit is installed, a third-party provider - known as an operate-maintain-commercialize vendor - will be responsible for leasing the fiber and other related infrastructure from the state.

Work on the 201 mile-long project includes installation of conduit, pull boxes, fiber-optic cables, node building, load center and other related work.

What to Expect

Construction will begin early 2025 and is anticipated to be completed in summer 2026. Work will occur in the ADOT right of way. During construction, drivers on I-40 can expect single-lane closures during weekdays, with no weekend or holiday restrictions anticipated.

In the 2013 DCR, operational issues related to the proximity of a Pilot Flying J truck stop to the crossroad intersection with the westbound I-40 ramps. The original DCR recommended a long-term solution of constructing the interchange 800 feet to the east and constructing new roundabouts at the ramp/crossroad intersections to improve overall TI operations. Since then, Coconino County constructed the recommended roundabout from the 2013 DCR on Shadow Mountain Drive and worked with Pilot Flying J to modify the circulation of trucks approaching and departing the truck stop. This resolved many of the immediate issues on I-40, although other challenges were created on Shadow Mountain Drive.

ADOT and the County initiated this DCR update based on traffic projections from recently proposed developments that significantly increase long-term traffic volumes and congestion in the area.

Project Flyer

Project Area Map

Project Scope:

The I-40 DCR will be updated by developing new alternatives and identifying a preferred alternative for the Bellemont area (study limits: I-40 MP 182-188). This will allow the county to be more competitive in applying for a federal Rebuilding American Infrastructure with Sustainability and Equity (RAISE) grant.

The vital first steps of preparing the DCR update document and reaching 15% design will confirm and prioritize the project goals and objectives.

A key component to this phase of the project is to determine the specific interchange location, type and overall footprint of the project. The deliverables for this phase are the scoping document preparation, traffic operation modeling, preliminary interchange and intersection layouts and the baseline cost estimate.

Project Area Map

Major elements of the project include:

• Adding one travel lane in each direction between mileposts (MP) 256 to 260.
• Constructing a center-turn lane between MP 256-257 and center median between MP 257-260.
• Constructing a new frontage road for the Diamond Point subdivision.
• Constructing three wildlife crossovers. 
• Improving and/or installing drainage and sediment-control facilities, including culverts, pipes and ditches.
• Removing, replacing and extending guardrail, as necessary.
• Dedicated right-turn lane for eastbound SR 260 at Lions Springs Road and westbound SR 260 at Dealers Choice Road. (These features were added as a result of public input received at the June 6, 2024 public meeting).

Background

This segment of SR 260, known as the Lion Springs section, was part of an ADOT study initiated in the early 1990’s to evaluate growing traffic volumes, safety considerations and overall improvements to approximately 40 miles of SR 260 between Payson and Heber-Overgaard. Final recommendations, including widening SR 260 from two to four lanes, were documented in a Location Design Concept Report (LDCR) and Environmental Impact Statement (EIS) with the Record of Decision signed on Jan. 31, 2000. An updated EIS was completed in September 2023 to account for any changes that occurred over the past 20 years and to ensure the design plan conforms to current federal regulations. 

The Lion Springs Section is the last of the six projects between Payson and the Mogollon Rim to be completed.

The planned improvements will tie into the already widened sections of SR 260 east and west of the project.

Need for the project

The Lion Springs segment of SR 260 is the only remaining two-lane highway section between Payson and the Mogollon Rim. Because of the capacity limitations, this 4-mile segment creates a traffic bottleneck during periods of heavy volumes, especially on summer weekends and holidays, resulting in traffic congestion. Completing the Lion Springs segment will help relieve delays for local and regional travelers by providing four travel lanes between Payson and the Mogollon Rim.

Design and Construction Timeline

The project is currently in the final design phase. Final design is scheduled to be completed in summer 2025. Funding to construct the project is planned to become available in July 2025. Construction will likely begin in spring 2026, although the construction schedule has not been finalized. Once work does start, the anticipated construction duration will be about three and one-half years, when factoring in anticipated annual winter shutdown periods.
