Security stepped up for Capitol Fourth

WASHINGTON - To ensure the safety of revelers taking part in Capitol Fourth festivities, officials are taking additional security measures.

Gates open at 3 p.m. All attendees will go through metal detectors and have their bags checked at one of eight security checkpoints.

"We are continuing to monitor the situation and tweak our plans. There are no credible threats against this event, but the United States Park Police and their law enforcement partners continue to monitor throughout the day and beyond," spokesperson for the National Park Service Mike Litterest said.

First aid stations and safe haven locations are scattered throughout the National Mall in case of an emergency.

Visitors are not permitted to bring alcohol, glass containers, drones, bikes or weapons of any kind. For a full list of prohibited items, click here.

Parking is limited so using public transportation is encouraged.
