The 395 traffic circle overpass that is adjacent to Gunston Rd is a traffic and safety hazard. I routinely witness cars speeding up and ignoring the yield sign as they prepare to enter the 395 highway ramp, presenting a hazard to cars in the traffic circle, especially those exiting onto Gunston Rd with a narrow lane merging into Quaker Lane where oncoming cars are failing to yield. There are regular accidents here and it seems it could be avoided or at least improved with new signage such as a stop sign or a change in traffic pattern. Please review the traffic pattern; we would appreciate anything you can do to improve the neighborhood!
