The value of these charts is that they provide a breakdown of the cost estimates of individual components of the bridge, and taken with the figures on Page 3 of the Preliminary Financial Assessment (PDF), we get a fairly complete picture. This information is hard to come by, either as a deliberate plan to favor road construction, or out of general obtuseness, depending on how much you want to use Hanlon's razor.
Code | Component | Cost in millions |
---|---|---|
BHB1 | Bridge with HO/T lanes | $ 5,180 |
BR1 | Commuter rail capacity on bridge | 1,220 |
RWH1 | Highway "improvements" (widening) | 1,800 |
RB1 | Rockland HO/T lanes | 263 |
RB1 | Rockland busway | 800 |
WB1 | Westchester bus lanes | 560 |
WB2 | Westchester busway | 2,210 |
RR1 | Rockland commuter rail | 4,410 |
WR1 | Rail connection to Hudson Line | 1,500 |
WR2 | Westchester light rail | 2,295 |
WR3 | Westchester commuter rail | 7,080 |
WR3 | Westchester commuter rail | 7,080 |
The $16 billion figure (estimated to be $23 billion after inflation and debt service) you often hear bandied about comes from the current Alternative 4D: in Tier 1, BHB1 + RWH1 = $6,980,000; in Tier 2, RB1 + RR1 + WB1 + WR1 = $8,383,000. However, as I've written before, the organization into tiers was completely arbitrary and decided behind closed doors, subject to none of the rigorous and intensive public participation requirements of the rest of the project.
You can kinda sorta see why they would want to build the bridge before putting in the "BRT" lanes (they're actually High Occupancy/Toll lanes and don't qualify for federal transit funding), but there's absolutely no reason why the $1.9 billion in "Highway Improvements" (reconstructing the Thruway interchange with the Westchester Expressway at Exit 8 and widening the Thruway from the bridge west to Exit 12) need to be done before anything else. So I'm going to do my own Pick-A-Mix, and I suggest you try yours.
Phase 1: WB2 + RB1 = only $823 million, but I would make the Rockland "BRT" a real exclusive bus lane connecting to a reversible bus lane in the middle of the existing bridge. The total cost would be well below $4 billion dollars, and it might just take enough cars off the bridge so that there would no longer be any justification for replacing the bridge.
If the demand is there, Phase 2 would be BBH1 + BR1 + RR1 + WR1, for a total of $12,310,000. The total is slightly more than the current DOT proposal, but you could probably shave a few million off that by only building six general-traffic lanes on the bridge instead of eight. What's your mix?
