Unpaved section of roadway to remain closed until spring

SAFFORD – The upper, unpaved section of State Route 366, which ascends Mount Graham in the Pinaleno Mountains southwest of Safford, has closed for the winter, according to the Arizona Department of Transportation.

The closure is in effect through April 15. 

SR 366, also known as the Swift Trail, begins about 5 miles south of Safford off of US 191. 

The highway is closed about one-half mile past the Coronado National Forest’s Shannon Campground, at the end of the pavement. 

Motorized vehicles aren’t allowed on SR 366 past the locked gate. Hikers, mountain bikers and cross-country skiers can still use the area.

ADOT will close lower portions of SR 366 as needed to clear snow.

PHOENIX – With springtime upon us, the Arizona Department of Transportation reopened three White Mountains-area state highways Thursday, April 15, after being closed for the winter.

State Route 261 runs from State Route 260 near Eagar to Big Lake, while State Route 273 goes from SR 260 to Sunrise Park and Big Lake.

State Route 473, runs south from SR 260 on the White Mountain Apache Reservation, to Hawley Lake.

State Route 366, which leads up Mount Graham near Safford, also reopened on April 15. However, ADOT is still in the middle of a roadway repair project and drivers should continue to expect delays on SR 366 as work continues. The project is to repair damage caused during the 2017 Frye Fire on Mount Graham.

Another highway that closes for the winter, State Route 67, leading to the North Rim of Grand Canyon National Park, is scheduled to reopen with park facilities in mid-May.

When traveling this year, please remember to do the following:

  • Make sure all occupants in a vehicle are buckled in.
  • Check tire pressure, fluids and more to make sure a vehicle is in proper running condition.
  • Be patient, including not following other vehicles too closely and building in extra travel time.
  • Get enough sleep before the trip.
  • Bring extra water and food.
  • Never drink and drive.
  • Check for information about highway restrictions and more by visiting az511.gov, calling 511 or following ADOT on Twitter (@ArizonaDOT).

Snow melting. Flowers growing. The swallows returning to Capistrano. All signs of spring finally returning after months of winter. 

In the world of transportation, there is another unmistakable sign that warmer weather is here to stay: The annual reopening of state highways in northern Arizona.

Starting today several state highways leading to popular outdoor destinations have reopened including:

  • State Route 261 between Eager and Big Lake in the White Mountains
  • State Route 273 between Sunrise Park and Big Lake in the White Mountains (that's the highway in the photo to the right, taken last year)
  • State Route 473 between State Route 260 and Hawley Lake in the White Mountains.

In addition, State Route 366, known as Swift Trail, has reopened above Shannon Campground on Mount Graham. However, ADOT is still in the middle of a roadway repair project and drivers should continue to expect delays on SR 366 as work continues.

And once spring is fully in swing, State Route 67, leading from Jacob Lake to the North Rim of the Grand Canyon will reopen. That is currently scheduled for mid-May. That's the highway in the bottom right photo, which was also taken last year.

These highways are closed in the winter months due to the significant levels of snowfall each receives. The closures also allow ADOT to best use its resources keeping more heavily traveled highways open.

To reopen state highways after a long winter's nap involves a fair amount of spring cleaning. And by spring cleaning we mean using heavy-duty snowblowers to clear the road for eager motorists. 

We welcome everyone to take a drive through high country again, but remind you to continue to be safe. If you are heading out, take normal precautions such as:

  • Make sure all occupants in a vehicle are buckled in.
  • Check tire pressure, fluids and more to make sure a vehicle is in proper running condition.
  • Be patient, including not following other vehicles too closely and building in extra travel time.
  • Get enough sleep before the trip.
  • Bring extra water and food.
  • Never drink and drive.

PHOENIX – Motorists on State Route 366 (Swift Trail) near Safford should expect intermittent delays starting Monday, Jan. 4, to repair damage from the 2017 Frye Fire on Mount Graham.

The work is scheduled for up to two years on SR 366 between mileposts 118 and 140. Key elements of the project include:

  • Removal of burned trees
  • Repairs to the road surface in some locations
  • Drainage repairs
  • Box culvert replacements
  • A chip seal on the paved portion of the highway

While SR 366 will remain open during repairs, drivers should continue to expect standard wintertime closures on the upper, unpaved portion of the highway. 

Most work will occur on weekdays, with some weekend work possible. Drivers should expect delays of up to 30 minutes. The contractor may work on two locations at a time, which could lead to multiple delays for drivers traveling through the area. Signals or flaggers will be used to control traffic.

ADOT is performing the repairs in cooperation with the Federal Highway Administration and the U.S. Forest Service.

Drivers should proceed with caution, slow down and watch for construction personnel and equipment. For more information, go to the project website.

PHOENIX – With the winter months rapidly approaching, the Arizona Department of Transportation will close State Route 473 in the White Mountains area and State Route 366, also known as Swift Trail, heading up Mount Graham in southern Arizona for the winter on Monday. Nov. 16.

State Route 67 leading to the North Rim of the Grand Canyon will close on Dec. 1, while other White Mountains area highways such as state route 261 and 273 will close by Dec. 31. These highways could close sooner depending on the weather.

ADOT closes these highways annually as part of the agency’s winter shutdown schedule due to significant amounts of snowfall these regions typically receive.

ADOT reminds motorists heading into snow country to drive with caution and follow this advice:

  • Don’t let GPS and navigation apps replace common sense. When a highway is closed, a suggested alternate route involving an unpaved, unplowed road can lead you into danger.
  • Pack an emergency kit, a fully charged mobile device, extra clothing, blankets, water and snacks.
  • Slow down. Drive defensively. Be patient and allow additional time for your trip. Never pass a snowplow.
  • Leave sufficient space between your vehicle and those ahead of you. Give yourself plenty of room and time to stop or to avoid hazards.
  • Make sure your vehicle has plenty of fuel.
  • Check weather and road conditions before you travel. Let someone know your route.
  • Bring a small bag of sand (or cat litter) for wheel traction.

PHOENIX – The Federal Highway Administration is providing $7 million in emergency relief funds to help cover the Arizona Department of Transportation’s cost of repairing two state highways damaged by flooding last summer.

A long stretch of State Route 88 northeast of Apache Junction experienced structural erosion following an intense monsoon storm last July. The highway remained open while ADOT made emergency repairs, and now much of that stretch is part of a previously planned safety-improvement project.

On Mount Graham in southeastern Arizona, runoff from areas scarred by the Frye Fire, which started in early June, damaged the upper reaches of State Route 366, also known as Swift Trail. Because of damage to the roadway and concerns about flash flooding from burned areas, the highest reaches of the highway remained closed until mid-September.

Governor Doug Ducey issued an emergency declaration for both highways.

The Federal Highway Administration’s Emergency Relief Program reimburses state and local jurisdictions for the repair or reconstruction of highways, roads and bridges damaged by catastrophic events.

The $7 million reimbursement allows ADOT to put money spent on these emergency repairs toward other highway projects.

The emergency funds cover the cost of initial repairs to both highways, emergency repairs to SR 88 and preliminary design work to address longer-term issues from flooding along SR 366. ADOT will seek an additional $4 million in emergency relief funds for permanent restoration on SR 366.

A bridge to better picnicking on Mount Graham

A bridge to better picnicking on Mount Graham

A bridge to better picnicking on Mount Graham

August 11, 2017

Back in 1935, a little bridge at Wet Canyon helped open up the beauty of Arizona’s Mount Graham for hiking, camping, picnicking and all sorts of outdoor activities on Graham County’s tallest peak.

Lately, though, the old bridge has been as helpful to picnickers as Yogi Bear’s fondness for pic-i-nic baskets.

Monsoon rains of the past two weeks washed debris off the mountain and into the drainage at Wet Canyon. Some of it is from the recent Frye Fire, but it’s also from a fire that occurred back in 2004. All of the debris was too much for the 80-year-old bridge, which had only a small opening for water to pass through. The result was flooding that closed some recreational areas and washed away picnic tables from the Wet Canyon Picnic Area.

Arizona Department of Transportation crews had already built a new bridge at this spot on Swift Trail (State Route 366). With cooperation from the U.S. Forest Service and other agencies, ADOT crews removed the old bridge in just two days this week.

Brian Jevas, assistant district engineer for ADOT’s Southeast District, shot the before, during and after images above while standing on the new bridge, which is higher and has plenty of room for water and flood debris to get by.

SR 366 remains closed indefinitely at Ladybug Saddle because of storm damage and concerns about flash flooding. Drivers should watch for ADOT and U.S. Forest Service crews in the area.

Recreational areas at Noon Creek, Angle Orchard, Wet Canyon and Turkey Flat are open thanks to some hard-working folks who did fast work with the old bridge this week. Enjoy.
