Sadly, the 1902 Livingston Ave. Rail Road Bridge – the only east-west passenger RR crossing of the Hudson – seems to be nowhere as far as being replaced. The plan seems to be to let it fall in the river, or, as in the case of the Crown Point NY-Vermont Bridge, have it declared unusable so we can spend scrillions on “emergency” replacement. Then everyone can pat himself or herself on the back for having “saved the day.”
People on bicycles who want a water-level route across the river to access Rensselaer or Albany are counting on Amtrak/Conrail/NYSDOT et al. to reinstall a pedestrian/bicycle patch on the new bridge.
