The Gateway International Bridge at Brownsville was shut down for the second time this week due to a large group of people who attempted to cross the bridge without proper documentation, according to officials.

The bridge was shut down for three hours on Monday. Tuesday’s shutdown lasted 25 minutes.

Noticias RGV —Channel 5 News’ Spanish affiliate — captured video of Mexican police limiting the amount of cars allowed to pass through the bridge. 

U.S. Customs and Border Protection’s website reported that wait times for vehicles are delayed by 120 minutes as of Tuesday evening.

Officers with the Brownsville Police Department were called in by CBP for backup.

“If we see that they're being overtaken, then we're going to do whatever we can to help them push people back,” police spokesman Martin Sandoval said. “But we're not going to do anything until we receive the word from border patrol, this is their scene."

CBP said the large groups did not have the proper paperwork to cross into the country, and did not make an appointment through the CBP One app to lawfully seek entry in the U.S.

Sandoval said the Gateway International Bridge is the only port of entry police were asked to monitor, adding that officers will be out there for the rest of the day.
