Before MGM National Harbor, Prince George’s County’s entertainment resort, even opened its doors to the public this Wednesday, people were already crowding the elevators of the parking garage, waiting to get in before the official opening at 11 p.m. Despite having 5,000 parking spaces in the resort, the garage filled to capacity within the first hour of opening, according to NBC Washington.

NBC Washington further reported that “police shut down the Beltway Outer Loop exits 2A, 2B and 3B to National Harbor to relieve traffic on Woodrow Wilson Bridge.”
Once again, the next day, the garage filled to full capacity by roughly 2 p.m.

In order to prepare for the traffic that the opening would bring, National Harbor management initiated an enhanced traffic plan that completed by December 1. Washington Business Journal reported that this plan restructured and widened lanes, introduced electronic signage, added parking, and modified traffic signals.
John Townsend, AAA Mid-Atlantic's manager of public and government affairs, told DCist that motorists "can expect a 6.2 percent increase in traffic volumes on the interchange near the [site].” Because of this, drivers should take alternative routes during the resort’s peak business hours.
If less interested in driving to the casino and more interested in taking public transportation, there are a variety of options, which can be found on the MGM National Harbor website here.
