Green Street Gate alternative Published Aug. 20, 2010 ROBINS AIR FORCE BASE, Ga. -- Users of the Green Street Gate, which is closed for two months for the installation of pop-up barriers, are encouraged to enter and exit the base through the National Guard Gate. Few took that option Monday, the first day the gate closed, and overloaded the Watson Boulevard Gate, said Erica Orr, a 778th Civil Engineer Squadron traffic engineer. The National Guard Gate, just north of the Green Street Gate, is open weekdays from 5 a.m. to 6 p.m., except holidays. Drivers can also enter and exit through the Russell Parkway and Martin Luther King Boulevard gates, but Orr said the National Guard Gate is the best alternative for those who work in the flightline area.
