I concur with the letter writer regarding the crosswalk near the G Street undercrossing. I just have one disagreement with her, or maybe just an add-on comment. It is often hard to even see the lights flashing there when you are coming up from under the bridge until you are right on top of it — even when you are going the speed limit. It is not a very safe place for a crosswalk. What about putting some sort of a flashing signal much earlier that will come on when the crosswalk lights are flashing to let us know sooner?
