A stop sign was posted about a year ago on the custis trail at the parking lot exit from the Marriott Hotel onto Lee Highway. This is a sidewalk/trail and a driveway exit...not a place where a stop sign can legally be required for pedestrians/cyclists. It's also unclear if the Arlington County is responsible for posting this sign to begin with. Cars coming out of that exit must to yield to pedestrians/bicycles and placing a stop sign on the trail only helps to legitimize failure to yield behavior from drivers. It's also unclear - is the stop sign for all trail users or just bikes? A similar stop sign at Custis Trail and Scott street was removed for this same reason.
Better yet, Arlington County should consider removing that exit from the hotel altogether. It has poor sight-lines for all users and there has been more than one crash there, especially given that drivers entering onto Lee Highway often fail to look right for foot/bicycle traffic due to the one-way nature of Lee Highway. Traffic can easily exit the Marriott parking lot (including large buses) through the existing Ft. Meyer Drive entrance/exit.
