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?
