As a New Yorker born and bred, I couldn't resist taking a crack at
this one, and luckily, I have my son with me to help out.

Turns out that NYC has some of the information you're looking for, but
not broken out in quite the way you asked.

We found daily traffic numbers for all the bridges and tunnels for Manhattan.

The numbers are presented in two different ways.  For some of the
bridges and tunnels, the numbers are broken out as:

Commuter Vans 
Commercial Vans

while for some of the other bridges and tunnels, the break out is simply:

(with vans and light trucks included in Autos).

It's not quite what you asked for, but sometimes it's necessary to
work with what's available.

Will it meet your needs?

Let us know please.

hi thanks for helping out
i think what u r refering to is the PDF found on MTA DOT site. but the
problem is that is breaks down the traffic for 13 free bridges but for
paid tunnels/bridges they only say total enter/leave manhattan data
without a breakdown.
now holland tunnel does not allow commercial traffic inbound to
manhattan therefore i was able to estimate traffic but for other
tunnels/bridges traffic is all inclusive both commercial/passenger.

but unless its not the 117 page report i am talking about maybe i will
be ok with auto / buses / truck breakdown for the remaining

let me know

Take a look at the "NYC Traffic" file at this link:

to see what the data for the Holland Tunnel, and other MTA operations,
looks like from the report I found.

Data for the other B&T's in Manhattan are in the other format I
mentioned earlier (Commercial Vans, Commuter Vans, etc).

Does that work for you?

Well out of autos it would be great to know how many of them are
INBOUND to Manhattan + how many of them are commercial. if i could get
an answer to at least one of them i think i be happy.
do all the bridges accept commercial traffic?

Thanks for being patient while my son and I explored the available information.  

This turned out to be quite complicated, because the traffic stats are
presented in so many different formats -- daily, yearly, hourly max,
one way traffic, two-way combined, all vehicles, vehicle breakouts,
and so on.

But I think we've managed to pinpoint the numbers that best meet your
needs, starting here:

2004 Annual Report of The Port Authority of New York and New Jersey.

Schedule G - Facility Traffic [page 87]
(Eastbound Traffic -- entering Manhattan)

George Washington Bridge

Automobiles 49,377,000 per year / 365 = 135,279 per day

Buses 606,000 / 365 = 1,660

Trucks 4,219,000 / 365 = 11,559

Total vehicles 54,202,000 / 365 = 148,499

Lincoln Tunnel

Automobiles 18,541,000 / 365 = 50,797

Buses 2,051,000 / 365 = 5,619

Trucks 1,141,000 / 365 = 3,126

Total vehicles 21,733,000 / 365 = 59,542


For the other crossings, the NYC Department of Transportation has a
comprehensive report of traffic in and out of Manhattan that analyzed
2003 data in great detail:
2003 Manhattan River Crossings

[page 1 has a very handy map showing how the 948,213 vehicle crossings
per day into Manhattan cross over the numerous bridges and tunnels
that connect it to the rest of the world]

2003 Average Daily Traffic Volumes To and From Manhattan
[numbers shown are 'To Manhattan']

Brooklyn Bridge 67,483

Henry Hudson Bridge 38,509

Brooklyn-Battery Tunnel 31,394

Queens-Midtown Tunnel 47,180

Triborough Bridge 50,626

The above data are for total traffic flow into Manhattan.  

Break out stats are available as well, but only for two-way combined traffic:

2003 MTABT & PANYNJ Facilities
24 Hour Two-Way Vehicle Classification

MTABT FACILITIES         Autos     Buses   Trucks     Total

Brooklyn-Battery Tunnel  51,322   2,400    2,549     56,271

Henry Hudson Bridge      71,769       0      440     72,209

Queens-Midtown Tunnel    77,807   1,145    6,425     85,377

Triborough Bridge        89,289     949    2,939     93,177


Fortunately, there are data on total inflow/outflow that allow us to
figure the percentage of traffic coming into Manhattan for each

[pg 70 entering v leaving Manhattan ]

Brooklyn-Battery          31,394      24,877         31.3/56.1  = 55.8%
[that is, 55.8% of the traffic through the Bklyn-Bty Tunnel is headed
INTO Manhattan]

Queens-Midtown            47,180      38,197         47.2/85.4  = 55.3%

Triborough Bridge         50,626      42,551         50.6/93.1  = 54.3%

Henry Hudson              38,509      33,700         38.5/72.2  = 53.3%


So....using the above percents, we can pro-rate the break-out
statistics for inflow traffic only:

Daily Traffic Into Manhattan

MTABT FACILITIES          Autos     Buses   Trucks     Total

Brooklyn-Battery Tunnel   28,638    1,339    1,422     31,399

Henry Hudson Bridge	  38,253        0      235     38,487

Queens-Midtown Tunnel     43,027      633    3,553     47,213

Triborough Bridge         48,484      515    1,596     50,595


Hope that's all perfectly clear, and what you needed.

But as always, if there's anything else we can do for you, just let us
know by posting a Request for Clarification.

Thanks a lot,
