 In Timonium, Nick Heinele, WTOP News. Middleburg is full of history, but there could soon be something new happening there. WTOP's Neil Augenstein says this morning it's something that could cost you a few bucks. Here on Middleburg's Washington Street, which is Route 50, today the speed limit is 25 miles an hour. But the town council is considering a recommendation from the police chief to drop the speed on this main street through town to 20 miles an hour.
