Drivers on Interstate 17 between Flagstaff and Munds Park should prepare for traffic delays this week. The Arizona Department of Transportation (ADOT) has announced that lane restrictions will be in place due to ongoing construction work on a new wildlife overpass. This project aims to improve safety and support local wildlife.
The primary area of impact will be near Willard Springs Road. Motorists traveling through this section of I-17 will experience reduced lanes, with traffic shifted to accommodate the construction activities.
Key Takeaways
- I-17 traffic will be slow between Flagstaff and Munds Park.
- Lane restrictions are due to wildlife overpass construction.
- Work will primarily occur Monday through Friday, 7 a.m. to 5 p.m.
- The project improves wildlife safety and habitat connections.
- Completion is expected by fall 2026.
Impact on Interstate 17 Traffic Flow
ADOT officials have confirmed that traffic will be limited to one lane in each direction during the active construction periods. Crews will be shifting traffic from the southbound lanes of I-17 to the northbound side to create a safe work zone.
These lane closures are expected to cause significant slowdowns, especially during peak travel times. Drivers are advised to plan extra travel time or consider alternative routes if possible.
"We understand that construction causes inconveniences for drivers," an ADOT spokesperson stated. "However, this wildlife overpass is a critical project for enhancing safety on I-17 and protecting local animal populations. We appreciate the public's patience as we work to complete it."
Construction Schedule Details
The majority of the roadwork is scheduled to take place during daytime hours. ADOT has specified that crews will be active from 7 a.m. to 5 p.m. on weekdays. Drivers should anticipate the most significant delays during these times.
While specific dates for the lane restrictions were not detailed beyond "this week," motorists should remain alert for signage and traffic control devices throughout the affected stretch of highway.
Project at a Glance
- Location: I-17 between Flagstaff and Munds Park, near Willard Springs Road.
- Project Type: Wildlife Overpass Construction.
- Estimated Cost: $15.8 million.
- Partners: ADOT and Arizona Game and Fish Department.
- Expected Completion: Fall 2026.
The Willard Springs Wildlife Overpass Project
This construction is part of a larger initiative to build a wildlife overpass. The project represents a collaborative effort between the Arizona Department of Transportation and the Arizona Game and Fish Department. The total cost for this significant infrastructure development is approximately $15.8 million.
The primary goal of the wildlife overpass is twofold: to improve connections for local wildlife habitats and to reduce the number of vehicle crashes involving animals on I-17. Animal-vehicle collisions can pose serious risks to human safety and wildlife populations.
Why Wildlife Overpasses Matter
Wildlife overpasses, also known as ecoducts or wildlife crossings, are structures built over roads or highways to allow animals to safely cross busy thoroughfares. These structures help maintain ecological connectivity, allowing animals to access food, water, and mates across fragmented landscapes. They also significantly decrease the risk of collisions between vehicles and wildlife, which can lead to severe injuries or fatalities for both drivers and animals. Studies have shown that wildlife crossings can reduce animal-vehicle collisions by 85% or more in some areas.
Benefits for Wildlife and Drivers
The new overpass will create a safer passage for various animal species that inhabit the forests surrounding I-17. This includes deer, elk, and other smaller mammals that frequently attempt to cross the busy interstate. By providing a dedicated, safe crossing point, the project aims to minimize disruptions to animal movement patterns and prevent hazardous encounters with vehicles.
For drivers, the reduction in animal-vehicle collisions means a safer travel experience. Such incidents can cause significant vehicle damage, injuries, and even fatalities. According to data, collisions with large animals like elk can be particularly dangerous due to their size and weight.
Long-Term Project Outlook
The wildlife overpass project is a long-term undertaking. ADOT anticipates that the entire construction will be completed by fall 2026. This extended timeline reflects the complexity and scale of building such a specialized structure over an active interstate.
While the current lane restrictions are temporary for this week's work, motorists should be aware that further construction activities and potential delays will occur periodically until the project's completion. ADOT regularly provides updates on its website and through traffic alert systems.
Staying Informed on Roadwork
Drivers can receive the latest traffic alerts directly to their phones. For those using KTAR News, texting "TRAFFIC" to 620620 provides real-time updates. It is always recommended to check ADOT's official channels for the most current information before traveling, especially when planning trips through northern Arizona.
Other major roadwork projects are also underway in northern Arizona, including pavement improvements on I-40. These combined efforts highlight the ongoing investment in infrastructure development and maintenance across the region, all of which can impact travel times.
This wildlife overpass represents a proactive step in balancing transportation needs with environmental conservation. It is designed to ensure both human safety on the roads and the well-being of Arizona's diverse wildlife.
