PHOENIX — Recent snowstorms combined with the long holiday weekend means winter recreation areas along US 180 near Flagstaff are expected to see heavy traffic, according to the Arizona Department of Transportation.

Motorists using US 180 during Martin Luther King Jr./Civil Rights Day weekend should expect a long queue into Flagstaff after popular snow-play areas close between 4 p.m. and 4:30 p.m. Making an earlier start back may help motorists avoid the heaviest traffic.

To avoid congestion through Flagstaff, consider taking an alternate snow-play route through the city via the Butler Avenue I-40 exit. Signs direct travelers to and from US 180.

In addition to allowing for extra travel time, visitors should prepare as they would for any extended period in a snowy, icy or cold area, starting with a fully charged cellphone, plenty of fuel, drinking water and winter coats, warm blankets or both.

Don’t pull over on highways or interstates to play in the snow. It’s dangerous for you, other drivers and first responders.

Give snowplows plenty of room, starting with maintaining four car lengths behind a plow. Never pass a snowplow that’s clearing a road.
