On September 11, 2024, several U.S. ports of entry along the Southwestern border will temporarily close to honor the victims of the 9/11 terrorist attacks, coinciding with the 23rd anniversary of the tragedy. Customs and Border Protection (CBP) will observe a moment of silence at 5:46 a.m., the exact time the first plane struck the World Trade Center, leading to a halt in all vehicular and pedestrian traffic at Arizona border crossings. Specific bridges, including the Veterans International Bridge in Brownsville and the Juarez-Lincoln International Bridge in Laredo, Texas, will close from 6:45 to 8:00 a.m. for remembrance ceremonies. Travelers are advised to plan ahead and consider alternative routes during these closures, as minor delays are expected. CBP encourages the public to check wait times on their website for updates. Nearly 3,000 people lost their lives in the 2001 attacks, prompting these commemorative actions across the border regions.
