U.S. Customs and Border Protection (CBP) advises travelers that there will be a brief halt to northbound traffic early Thursday morning.

A moment of silence at 5:46 a.m. will commemorate the same moment Flight 11 crashed into the World Trade Center North Tower on September 11, 2001. Normal traffic will resume immediately following the brief ceremony. The Calexico West Port of Entry (downtown) and Tecate Port of Entry will be participating.
