Officials say all lanes have been reopened at the nation's busiest border crossing 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 Sunday that traffic in all 24 U.S.-bound vehicle lanes was flowing normally at the San Ysidro port of entry from Tijuana to San Diego.
Three lanes had remained closed until late Saturday.
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.
Mexico-bound traffic was never interrupted.
