Give me a bus connection to Perth Amboy. It is ridiculous that we have four bridges and only one gets regular non-express bus transit going on it. Right now, only way for me to go to New Jersey would be to either take the limited service S89 or go through Manhattan which is a huge detour. I live in Princes Bay and it's stupid that I have to make a huge circle through the city, spend more than 3 hours commuting, and spend nearly $20 just to get to somewhere that's only 5 miles away. Even a bus or light rail connection to Elizabeth over the Goethals Bridge would be better than the current state of a transit desert that Staten Island is.
Besides this, I think heavy rail would be the best option because the west shore has plenty of unused space for building a right-of-way, the west shore currently doesn't have access to the SIR, and heavy rail is faster, greater capacity, and would even merge with the existing SIR branch to allow people to transfer to it with connection to St. George and the ferry to Manhattan.
Or even better, how about finishing that tunnel under the Verrazano-Narrows bridge and finally connecting Staten Island to the subway as it's currently the only borough without it?
