Lanes on the eastbound 91 Freeway were shut down to accommodate a rescue helicopter Tuesday night after a motorcycle crash, according to the California Highway Patrol.
Traffic was already a mess due to the pending Thanksgiving holiday, but the freeway closure worsened the issue.
A SigAlert was issued at 7 p.m. at the Green River Road exit on the eastbound 91 Freeway.
The motorcyclist was airlifted to the hospital after the chopper landed on freeway lanes.
