It's been a few months now but i am still waiting to see why the flashing yellow light at Emory Church Rd and Georgia Ave just south of Olney has been converted to a timed traffic light.
It serves nothing but to halt any flow of traffic heading north from Emory Lane or south from Old Baltimore.
Is there a reasonable explanation for this?
It can't be because of the shoppers at Roots or Starbucks....can it?
