(Alex Goldmark, Transportation Nation) For the visual learners out there, Infrastructist came up with this infographic charting the growth in ridership—it has more than quadrupled since 1984. NJ Transit wants that green line above to keep getting fatter. But right now it can't. The agency says all the Hudson river crossings are currently at or near capacity already. The ARC tunnel would allow an additional 70,000 commuters to cross. Governor Chris Christie has said he's for the project, but that NJ can't afford it, particularly if there are cost overruns.
If you want moving visuals, here's the official NJ Transit promo video. (Still up, even though Gov. Christie says he's shutting the project down, pending the two-week review) It's a bit slow going at first, so fast forward to about 2:15 into the video to see renderings of the tunnel and new station (the computer generated commuters are a little creepy though, unless you're a fan of the video game the SIMS)
