A lone bicycle accident caused major traffic delays on State Route 179 on Tuesday, April 27.

At 11:07, a 59-year-old man lost control of his bicycle and crashed in the roadway along the bifurcated portion of northbound State Route 179 between mileposts 309 and 310, according to Gary Johnson, Sedona Fire District’s public information officer.

The area was formerly known as “the roller coaster” before the recent road construction bifurcated, widened and leveled the roadway, Johnson said.

The man, who was not wearing a helmet, suffered potential life-threatening injuries. He was airlifted by Native Air to Flagstaff Medical Center, Johnson said.
