I-5 Southbound Tunnel Reopens

The southbound truck tunnel on Interstate 5 reopened Thursday, a month after a multi-vehicle pile-up temporarily shut down the West Coast's main commercial route, the Associated Press reported.

The tunnel reopened 15 days earlier than expected, said Officer Patrick Kimball of the California Highway Patrol. Repairs were initially expected to take several months, AP said.

Authorities determined that 31 vehicles were involved in the Oct. 12 crash, according to AP.

Truckers use I-5, the main West Coast interstate linking Mexico and Canada, to haul produce from the Central Valley to Southern California and to move goods from the ports of Los Angeles and Long Beach.
