El Segundo : LAX Traffic Study Planned

City officials have agreed to chip in $75,000 for a study to determine how to improve traffic flow in the Sepulveda Boulevard tunnel under Los Angeles International Airport.

The El Segundo Employers Assn., a business group, said the cities of Manhattan Beach, Redondo Beach, Hermosa Beach and Hawthorne also have agreed to ante up a total of $75,000 for the $3-million study. About $2.4 million in federal money as well as $450,000 in Los Angeles county and city funds have also been earmarked for the study, which airport officials are expected to oversee.

Traffic flow within the six-lane tunnel, situated under runways at LAX, is expected to become extremely congested once work is completed on the Century Freeway in 1993.
