The future US 119 tunnel, which will be the second longest vehicular tunnel
in the United States, will start construction within 1-3 years in Kentucky.
It will be 2 lane and connect the seperate four lane segments of the
corridor highway.

I-70 has quite a few more tunnels in Colorado, probably 6 or so throughout
the state. Also, the Wheeling Tunnel is 4 lanes....even though only 2 of
them can be used by I-70 thru traffic, the other two are still part of the
Tunnel facility and still part of I-70.
Also I-80 has tunnels in Green River, WY and west of Elko, NV.

Brooklyn Battery Tunnel is unsigned I-478, not I-278.
Queens Midtown Tunnel is signed as I-495, but it technically not an
interstate...it is NY 495 signed as I-495 to avoid confusion.

Heck, if long underpasses count, i'll throw in a couple of those:
I-95 in NYC "under the Apartments" (The Trans Manhattan Expressway)
I-90 in Boston under Prudential Center
I-95 in Fort Lee, NJ....the approaches to the Lower level only of the GWB.

Well, if the decks over the FDR Drive count, then so should the Chestnut
Street and Dock/Spruce Street decks over I-95 in central Philadelphia.
(In the case of the Dock/Spruce Street deck, I-95 is actually below
grade; the deck at Chestnut Street is just above grade with Front
Street, but the highway is at grade with Delaware Ave on its opposite side.)
Ditto the deck over the Schuylkill Expressway from Walnut Street to 30th
St Station.
And what then of Seattle's "Freeway Park" over I-5? Or Chicago's Lower
Wacker Drive? (See where this is going? I think you opened a can of
worms. Of all the structures I've listed above, the only one I'd
consider a tunnel is the Dock/Spruce St stretch of I-95.)

Yes this actually is a tunnel. It's called the Lytle Tunnel. It goes under
a small urban park (Lytle Park), the only remaining houses I know of in
downtown Cincinnati (very nice), and a home that once belonged to the Taft
family (as in the President) and is now a museum. No idea why they tunneled
instead of cutting a "trench" type road. Also, it is only I-71 as US 50
leaves in an interchange just south of the tunnel.

Non-Interstate freeway: GA 400 in Atlanta - short tunnel goes

Not according to TXDOT. From
http://www.dot.state.tx.us/insdtdot/geodist/dal/mis/ih635/nownews.htm:
"West Section Freeway and Tunnel Sections – This is one of the main priority
projects for the LBJ Project to move into the design and right-of-way (ROW)
acquisition process. The lead-time necessary to secure consultant services,
initiate the design, secure funding, buy ROW and start construction make
this the top priority. This is a large contract for TxDOT. Appropriate
phasing and staging of the design and construction work will be paramount
for success. Local participation for project costs will help accelerate
this project. A push for this project will not impede making progress in
other areas of the corridor."
And from ftp://ftp.dot.state.tx.us/pub/txdot-info/dal/news/lbjnews5.pdf:
"The twin tunnels for the Managed HOV lanes between Preston and Midway Road
have been exhaustively studied for safety, constructibility, cost,
maintenance and long-term operation. Tunnel experts from around the world
have shared their experiences in an effort to better understand exactly what
tunnels would entail. The result was a finalized decision to
include the tunnels and adopt the goal of implementing them early in the
reconstruction of LBJ, prior to main lane improvements, in order to maintain
through-traffic on LBJ from the completed Dallas High Five Interchange.
Again, hats off to TxDOT for their thoroughness and willingness to embrace
bold new road solutions."

In the meantime, there is the Dewey Square Tunnel, a cut-and-cover
carrying both directions of the otherwise-elevated Central Artery
underground at its southern end. Both directions of this tunnel will
soon be closed and rehabilitated into the southern end of the
southbound depressed Central Artery (northbound traffic will use a new
alignment under Atlantic Avenue several blocks east).
> Some notable non-interstate highway tunnels:
I don't think the City Square Tunnel (US 1/Northeast Expressway) in
Boston's Charlestown neighborhood has been mentioned. Replaced a nasty
tangle of elevated double-decked ramps to the Tobin Bridge in the late

project.

And a handful more: the connector from the SB West Side Highway/West

underneath the BBT toll plaza in Brooklyn, Bruckner Boulevard under the
Triboro Bridge interchange, Adam Clayton Powell Jr. Boulevard (aka 7th

the SB Brooklyn-Queens Expressway (I-278), and probably some more.

That's a long underpass, not a tunnel. The Cross Bronx Expressway has
longer underpasses. They're not tunnels either.

Under the Grand Concourse I believe, there's even a subway tube under
the Concourse and above the Cross Bronx. There's also 2 short tunnels
complete with ventalators(sic), one for each direction on the lower
GWB I-95 (Jersey side).
The front of the newspaper today has a picture of the giant dirt conveyer

I wouldn't call it a tunnel any more than I would say the same of the
Trans-Manhattan. There are a number of buildings that are built on air
rights above the highway.

US-1 Roosevelt Expressway passes under the Broad Street Subway, in
Philadelphia.

That one is definitely a tunnel.
I-95, Trans-Manhattan Expressway is still a tunnel IMO, just a 'cut and
cover' tunnel. I-95 in Manhattan is definitely in a cut, and part of it
is covered by the bus terminal. The part covered by the bus terminal is
certainly long enough to be a tunnel (a lot longer than it is wide).
What is the official difference between "long underpass" and "Tunnel"
anyway? And don't say ventilation systems, since one of the "long
underpasses" on the Cross Bronx has ventilation shafts (don't remember
which one) and the tunnels on I-40 in NC don't have them at all.
