Phoenix, AZ – Traffic Alert: SR 67 and SR 473 Close for Winter Season
Arizona drivers heading toward the high country should prepare for seasonal travel changes as two well-known mountain highways — State Route 67 (SR 67) and State Route 473 (SR 473) — have officially shut down for the winter months. These closures are part of the state’s annual safety measures and will remain in place until warmer weather returns in spring.
Why the Highways Are Closed
Both SR 67 and SR 473 sit at high elevations where heavy snow, icy pavement, drifting winds, and low visibility can make travel dangerous. Once winter storms begin, the routes become too hazardous for maintenance crews to keep clear, and routine snow removal is not performed in these areas.
-
SR 67 leads directly to the Grand Canyon’s North Rim, which closes every winter.
-
SR 473 runs through the White Mountains and is known for steep terrain prone to fast-changing weather.
The closures help prevent accidents, stranded motorists, and emergency rescues in remote regions where conditions can deteriorate quickly.
Impact on Travelers
Motorists should plan ahead, as access to these roads is fully restricted until spring. Locked gates and closure signs mean:
-
No travel is permitted on the affected stretches
-
No maintenance or snow clearing will occur
-
Emergency response may be delayed if someone enters a closed zone
Visitors heading toward northern Arizona should adjust plans accordingly. While the North Rim is closed, the South Rim of the Grand Canyon remains open year-round and is fully accessible via alternate routes.
Tips for Safe Winter Travel in Arizona
Even outside the closed corridors, winter conditions can affect many mountain highways across the state. Drivers are encouraged to:
-
Check road conditions before heading out
-
Carry warm clothes, blankets, water, and emergency supplies
-
Fill up with gas before leaving populated areas
-
Avoid unnecessary nighttime travel in high-elevation regions
-
Drive slowly on icy or shaded roads where black ice may form
What to Expect Ahead
The seasonal closures typically last until early or mid-spring, depending on weather patterns and snowpack levels. Once conditions improve, crews will inspect the roads, clear winter debris, and reopen the highways for public travel.
Until then, travelers are urged to stay alert, stay safe, and respect all posted winter-season restrictions.
