LOS ANGELES (AP) — California Gov. Gavin Newsom says a stretch of Interstate 10 in Los Angeles that was burned in an act of arson does not need to be demolished, and that repairs will take an estimated three to five weeks. Newsom announced the finding Tuesday, based on analysis of core samples taken from the freeway, a vital artery used by 300,000 vehicles daily. The fire erupted Saturday in two storage lots under an elevated section of the freeway, damaging about 100 columns. No arrests have been made and the investigation is ongoing. Officials have warned that the temporary closure of the stretch of I-10 will be felt beyond the city, possibly slowing the transportation of goods from the twin ports of LA and Long Beach.
