Traffic on Northbound Interstate 5 between Anderson and Redding was stalled late Thursday morning when a speeding motorcyclist hit an SUV. The crash occurred around 10:20AM a couple of miles south of Knighton Road in the construction zone. Witnesses estimated the motorcycle was going about 90 miles an hour and was splitting lanes, dashing between vehicles, when it smashed into the rear of a Jeep Cherokee in the fast lane. The rider was transported to Mercy Hospital with major injuries. His name and condition are not yet available.
