ADOT’s first TowPlow clearing stretch of I-40 faster, more efficiently

Innovative device allows one driver to clear two lanes

TowPlow in operation on I-17PHOENIX – An innovative new snowplow is allowing the Arizona Department of Transportation to remove snow and ice more efficiently by having one driver clear the width of two lanes.

The first TowPlow to join ADOT’s fleet of 200 traditional snowplows is assigned to 20 miles of Interstate 40 between Williams and Bellemont west of Flagstaff. The device saw its first use during this week’s snowstorm.

The TowPlow is a steerable trailer with a 26-foot blade that’s attached to the back of a regular snowplow truck. The combination, able to plow a 24-foot-wide path, lets ADOT clear more lanes in less time using less fuel.

“It’s been a very busy year for ADOT’s winter operations, and as we work through this latest storm the TowPlow has already been out on the highway plowing snow and ice,” said Dallas Hammit, ADOT’s state engineer and deputy director for transportation. “This new plow is a time-saving and safe addition to the department’s fleet of snowplow trucks and provides a higher level of service to all drivers and travelers.”

When possible, ADOT will run another snowplow truck alongside the TowPlow setup, clearing both lanes and the shoulder at once. To keep vehicles at a safe distance, a flag car will be positioned behind the snowplows traveling side by side.

ADOT will evaluate the TowPlow’s performance this winter before deciding whether to purchase more.

TowPlow Poster - What is a TowPlow, TowPlow Benefits, Safety Info for DriversAs with any snowplow, drivers need to do their part to stay safe:

  • Slow down: Stay well behind the safety vehicle that follows the TowPlow.
  • Don’t try to pass: The flag car and the plows will move over periodically and allow traffic to pass when it is safe to do so.
  • Remember: The road behind the TowPlow and other snowplows is the safest place to drive.

Drivers should always check highway conditions before heading out, especially during a winter storm. The ADOT Traveler Information Center, available at az511.gov or by calling 511, is an excellent source of information, as is ADOT’s Twitter account: @ArizonaDOT.
