Northbound Interstate 17 has reopened at Camelback Road after a Phoenix Police officer was involved in a motorcycle crash.
A spokesman for the Department of Public Safety said something in the roadway made the officer's motorcycle slip and fall and then skid 100 to 150 feet along the freeway.
Phoenix police said the officer, a 20-year veteran with the department, suffered serious injuries and will require multiple surgeries, but is considered to be in stable condition.
The spokesman declined to provide the officer's name.
The officer was on his way home from work. Police said if officers live in Phoenix, they are able to take their motorcycles home with them.
The single-vehicle crash was reported around 2:40 a.m. on Monday.
The freeway was closed while the crash was investigated and cleaned up. It reopened at 8 a.m., according to the Arizona Department of Transportation.
No other details were released.
