Officials say more lanes have been opened at the nation's busiest border crossing but three remain closed after scaffolding fell on more than a dozen cars and injured 11 travelers and construction workers.
U.S. Customs and Border Protection Agency spokeswoman Jackie Wasiluk said Saturday that three of the 24 U.S.-bound vehicle lanes were still shut at the San Ysidro port of entry from Tijuana to San Diego.
Border officials expect all the lanes to be reopened by Sunday.
Mexico-bound traffic was never interrupted.
Traffic was halted Wednesday after construction scaffolding collapsed onto eight lanes. A construction worker was seriously hurt, and 10 other people, including a pregnant woman, were taken to hospitals with minor injuries
