California Governor Arnold Schwarzenegger (R) smiles with Los Angeles mayor Antonio Villaraigosa before signing a bill which will speed up construction of a carpool lane on the San Diego 405 freeway at a construction site in Los Angeles January 13, 2006. The bill, SB 1026, allocates 90 million dollars and paves the way for an accelerated construction schedule for the lane to be built up to six years sooner than originally planned.
