Avoid I-77 northbound, state highway officials urge

Motorists should avoid Interstate 77 northbound Wednesday afternoon from the Harris Boulevard exit in Charlotte north through Huntersville and Davidson, the state Department of Transportation said in a traffic alert at 1:40 p.m.

Traffic is backed up due to an earlier wreck that closed all lanes, and it could take until 4 p.m. for the congestion to clear, highway officials said.
