NH1 Stops History Introduction of the NH1 National Harbor opened on April 1, 2008 with the opening of the Gaylord National Resort & Convention Center and has since got more attractions like Tanger Outlets and the Capital Wheel through the years. Under the request of Gaylord and National Harbor, WMATA announced new service connecting Southern Avenue station to National Harbor with the new route NH1 beginning on March 23, 2008. The new route will operate 7 days a week between 6 AM and 10 PM every 20 minutes during rush hours and 30 minutes during other times. The state of Maryland pays $312,000 annually for the NH1 operations. In June 2008, Gaylord National Resort and Convention Center have asked Maryland to fund for additional transit service since employees found it difficult to reach National Harbor.

The changes caused controversy among workers as they will now have to travel out further on the Green Line to catch the NH1. Service was also deducted in the morning with buses now arriving past 8:00 AM on the weekends. Gaylord requested for WMATA to restore the original routing back to Southern Avenue station. In response to the changes, Prince George's County created TheBus Route 35 to restore the connection between Southern Ave station and National Harbor.
