Attention, motorists frequenting the stretch of I-40 between Flagstaff and Winslow: asphalt maintenance is coming your way. A 10-mile section of the interstate is set to receive a fresh pavement surface starting September 24, as announced by the Arizona Department of Transportation. The affected area encompasses Meteor City Road (milepost 240) and Two Guns (milepost 230), with drivers advised to anticipate lane restrictions.

Travel through this corridor is about to get a tad slower, since the road will be condensed to one lane in each direction weekdays during the work. Resurfacing will kick off alongside the highway's edges, afterwards giving way to the main travel lanes, according to the ADOT announcement. Despite the inconvenience, the upgrades are scheduled for a pause during winter, with the entire endeavor wrapping up by fall 2026.

It's not just the surface getting attention—guardrails will see a replacement or installation, and lane markings are getting a refresh. Those interested in the project's finer details, or who need to keep abreast of real-time road conditions, can head over to ADOT's Arizona Traveler Information site at az511.gov, or download the AZ511 app, which is handy for Apple and Android users. And for those social media buffs, highway updates will be dished out on ADOT's Twitter page, @ArizonaDOT.

Those planning their daily commute or a cross-state road trip, it’s worth noting these dates and planning to avoid unexpected delays. While the journey might be slower for the time being, the long-term benefits of smoother and safer travels seem worth the temporary bottleneck.
