I dunno, where that sidewalk meets webster is a mess. They plonked the pedestrian signal to cross prospect right in the middle of the sidewalk, tricky to get a stroller by never mind a wheelchair.The city?/developer? built out a curb extension to get around the traffic signal foundations - the rest of that sidewalk is accessible for width -- but not for slope.
I remember thinking this when all the effort was made to get disabled access to the station from prospect and thinking the sidewalk is not suitable from either direction.
