USDA Stops Traffic in Beltsville
Dear Dr. Gridlock:
A very odd four-way stop was recently installed on Powder Mill Road, midway between Edmonston Road and the Baltimore-Washington Parkway on the Agriculture Department's Beltsville Agricultural Research Center.
The two roads that intersect Powder Mill at the new intersection from the north and south have no traffic to speak of.
The new stop just slows traffic on Powder Mill and lines it up at this new stop during commuting hours.
Do you know the background behind this new four-way stop?
