SCOTTSDALE, Ariz. — Authorities have reopened a portion of the Loop 101 freeway in Scottsdale that had been closed for several hours Monday after motorcyclist was killed in a crash.

Department of Public Safety spokesman Trooper Kameron Lee says a pickup truck struck the motorcycle that had broken down near the wall dividing the northbound and southbound lanes.

The collision caused a fire and threw the motorcycle’s driver from the northbound side into southbound side.

It’s unclear whether the pickup truck’s driver was injured.

Debris from the crash fell on southbound vehicles.

The freeway had been shut down so authorities could investigate the crash.
