What to Know about July 4 in D.C.

Maybe you've heard: Saturday will mark the 250th anniversary of the signing of the United States' Declaration of Independence. Major celebrations are on deck in the nation's capital, including the National Independence Day Parade on Constitution Avenue and annual fireworks show on the National Mall. For members of the George Washington University community who are staying in town, here are some basics to be aware of.

Work around changes on and near campus

Due to the multiple events and influx of crowds expected on Independence Day, extensive road closures and restricted-access areas will be implemented beginning July 1. These are expected to last through July 5, with normal road access restored by July 6.

Operations at GW will be affected in the following ways:

• The Flagg Building will be closed starting at 2 p.m. on July 2, reopening on July 6 as scheduled.
• All Foggy Bottom residential rooftops will be closed beginning at 7 p.m. on July 4.
• VEX will run on a regular summer schedule with delays possible. During the Palisades Parade on July 4, the Mount Vernon Campus stop will move to the W Street Gate.
• GW Safe Ride does not operate on designated university holidays. SafeRide and the late-night shuttle will not run overnight on July 3 into July 4 and July 4 into July 5.

Know before you go

If you're planning to watch the fireworks and "Salute to America" concert in person this year, be aware that enhanced security arrangements will also be in place on the National Mall. Ticket reservations are required to attend July 4 events, and pedestrians must pass through security checkpoints on Constitution Ave. NW or Independence Ave. SW. A full list of prohibited items-including backpacks, balloons, large signs and coolers-is available here.

If all that sounds like a lot of work, use the D.C. government's interactive tool to find a location where you can see the fireworks without getting to the Mall. If you do need to travel, Metro Rail will run increased service starting at 5 p.m., and fares will be free systemwide from 5 p.m. Saturday to 2 a.m. Sunday.

Beat the heat

Serious heat is expected this weekend, with temperatures potentially climbing over 100°. Heat's dangerous effects can be exacerbated by the D.C. area's typical high humidity, which affects sweat evaporation, the human body's most effective cooling mechanism. Experts from GW's Milken Institute School of Public Health and School of Medicine and Health Sciences have tips for heat safety, including:

• Spending as much time as possible indoors in air conditioning
• Taking cool showers or baths
• Avoiding strenuous activity or exertion
• Taking frequent rest breaks
• Staying hydrated: bring water any time you leave the house
• Cutting down on alcohol and caffeine, since these diuretics can lessen the body's ability to reabsorb water
• Wearing loose, breathable clothing in light colors, which reflect sunlight away from you

If you begin to feel or observe signs of heat exhaustion-which may include cool skin with goosebumps, a rapid pulse, dizziness, nausea or a headache-find a nearby cooling center or call 911. Untreated, these symptoms can lead to life-threatening heatstroke. Visit the D.C. heat readiness site for more information.
