Due to their cost and maintenance, highway tunnels tend to be few and far
between when compared to bridges or viaducts. They are rare enough, in fact,
that all of the Interstate tunnels can be listed here.

2di:
I-64: Hampton Roads
I-64/77: WV Turnpike Memorial. 2-lane. Bypassed in 1987
I-70: Eisenhower, Twin (at Clear Creek Canyon, CO), Wheeling (2-lane),
Allegheny Mtn
I-76: Tuscarora Mtn, Kittatiny Mtn, Blue Mtn. Also Allegheny Mtn. (3 others
were bypassed in the 1960s)
[Note: The Allegheny Mtn. is slated by the PA Turnpike Commission to be
bypassed]
I-90: Ted Williams
I-93: Big Dig/Central Artery replacement, under construction
I-95: Fort McHenry. Has four parallel 2-lane tubes.

3di:
I-278: Brooklyn-Battery
I-279: Fort Pitt
I-376: Squirrel Hill
I-395: Third Street (Washington, DC). Some of the access routes to I-395 are
tunnels themselves.
I-476: Lehigh
I-495: Queens-Midtown
I-664: Monitor-Merrimac
I-895: (Baltimore) Harbor

Very short; some of these might just be long overpasses:

I-10: tunnel at end of highway in Santa Monica
I-66: Rosslyn
I-71/US-50: Cincinnati riverfront?
I-75: under Peachtree St in downtown Atlanta
I-75/285: a single-lane tunnel is part of the northern interchange

Some notable non-interstate highway tunnels:

- Lincoln and Holland. NYC also has a short tunnel leading from the FDR Drive
to West St near the WTC site. As well as one under Park Ave. on a former
railroad bed south of Grand Central.
- Chesapeake Bay Bridge-Tunnel (US-13)
- Liberty Tunnels -- aka "Liberty Tubes" by the Pittsburgh locals.
- "Tunnel to Canada" -- from Detroit to Windsor.
- 2 new tunnels in Trenton, NJ (US-29) and Atlantic City.
- Road tunnel in downtown Pittsburgh?
- Alaska has modified a long railroad tunnel for use by trains or highway
traffic (at different times, of course). Single lane.

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.

Not exactly downtown, but the one under Duquesne University is the Armstrong

Holland is I-78. Lincoln is former I-495.
The Brooklyn Battery Tunnel is (secret) I-478.

Do the three long underpasses under parks on I-694 in Detroit count
as (short) tunnels?

It seems like Grover has left out quite a few tunnels. To add to his
list:

I-90: Seattle and Mercer Island tunnels.
I-80 in Wyoming and Nevada.
and how about the Hawaii Interstates?

Interstate H-3 has two sets of tunnels, the John A. Burns (formerly
Tetsuo Harano) tunnels about a mile long through the Koolau Range, and
the shorter Hospital Rock tunnels to the east.

Interstate H-1 has one tunnel, the short Middle Street Tunnel (eastbound
only) just before H-1 rejoins the Moanalua Freeway (HI 78/unsigned
Interstate H-201).

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.

Also in NYC, there are several on FDR drive under Gracie Mansion, and the
UN...although that might not be fully enclosed. There is the first Ave
Tunnel as well.

http://www.cahaltech.com/~roads/page.php3?page=roads_us121_wv shows a
general map. The tunnel will be located over Pine Mountain in Pike County.
It's in the first "dotted" "proposed" routes coming off of US 23 to West
Virginia.

Don't forget the tunnel on Yerba Buena Island on I-80 as part of the Bay
Bridge complex.

Isn't there a tunnel on 90-94 near downtown Chicago?

Do I-35 in Duluth and I-5 in Seattle count?

SB lanes of I-280 go through a tunnel at the CA-1/John Daly Blvd interchange
at the southern edge of San Francisco.

There's also the Posey and Webster tubes connecting Oakland, CA with
Alameda.

I-478 you mean. I-278 doesn't tunnel. It stacks on itself south of the
Brooklyn Bridge though.

The first one is to duck under (!) the BBT I-478. FDR also tunnels
under the UN building, which is fairly notable.

There are of course those outside the continent (several in France I've

West Haven, CT

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.)

Adding to this, it will "bypass"/go under the place where 119 currently
crosses Pine Mountain. 119 is still on its original alignment here IIRC and
trucks are banned from using it. This is basically the one obstacle to
making 119 a major through road in the area. Pine Mountain is over 100
miles long and has only one gap in it (at Pineville KY, where US 25E goes
through the gap) It is the same mountain I-75 crosses for 17 miles or so
near Jellico.

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.

I'd call it a long overpass

I'm surprised no one here mentioned the San Francisco-Oakland Bay Bridge
bi-level tunnel through Yerba Buena Island--the Bay Bridge is part of
Interstate 80.

Also, in DC there is a short tunnel on the E Street expressway.

How can you forget the beautiful Hanging Lake Tunnels on I-70 in

How about the Brooklyn-Battery Tunnel that goes from the west side,
under the Battery and under the East River mouth into Upper New York
Bay?

While it's not a 100% done deal yet, current plans are to add twin 1.5-2.5
mile, 3 lane tunnels to IH-635 in north Dallas. While they may be
cut-and-cover, most likely they'll be deep bored, which means they'll
(supposedly) be the longest and widest mined automobile tunnels in the
world. More interestingly, they would (supposedly) be the only automobile
tunnels in the world built simply to add capacity to an existing road, as
opposed to getting around some obstacle. The type of rock in this area is
just about ideal for tunnel boring (soft enough to easily bore, but hard
enough that minimal additional support is required), so the cost of boring
the tunnels compares very well to the cost of the ROW required to instead
widen the highway through this corridor. Add the easier logistics of boring
a tunnel and it gets close to being a no-brainer.

That's not an interstate. The 'Congress Extension' is a glorified city street.

Non-Interstate freeway: GA 400 in Atlanta - short tunnel goes
directly under a building; MARTA (rail system) tunnel runs between the
NB and SB GA 400 tunnels.

Also in Atlanta: There's talk about extending one of the runways at
Hartsfield; when that's complete, I-285 on the south side of the
airport will land up with a short cut-and-cover tunnel.

Lots of them: The Chattanooga, TN area has several tunnels through
various ridges, including ones that carry two multiplexed US routes
(41/76 and 11/64).

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
80s/early 90s in the so-called Central Artery North Area (CANA)
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
Avenue) at its north end, the ramp from WB Queens Boulevard (NY 25) to
the SB Brooklyn-Queens Expressway (I-278), and probably some more.

That's a long underpass, not a tunnel. The Cross Bronx Expressway has

Under the Grand Concourse I believe, there's even a subway tube under

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

Hmm...how about where the Cross-Bronx goes through the ridge the Grand
Concourse sits on? It looks tunneled through rock to me. For that matter,
where else does a highway go under an already underground subway?

Old trolley tunnel. The tunnel on First Ave is, I believe, newer
construction.

I wouldn't call it a tunnel any more than I would say the same of the

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.

The "Big Dig" (soon to be I-93) passes under Boston's Red Line subway,
which passes under a future busway, which passes under a subway lobby,
which passes under city streets.

Thanks. And it's the only *highway* tunnel through a hill. (Or are we
distinguishing between a hill and a mountain? In either case, there's
the Hoosac, which allowed the Boston and Albany to actually reach Albany.)

--Sandy, who always wondered when that tunnel opened--the lettering on

Once you get to I-91 the first time, freeway traffic can use that, so
there's no need to have a parallel freeway when it would mean moving or
closing local businesses. Then back in Hartford, 91N-84E and 84W-91S
traffic uses it, and it's a freeway again.

The underwater one on I-90 may. But I-93 goes under (I-93 goes over the blue
line).

I'll grant that one.

The 79th Street transverse road through Central Park tunnels through
rock near Belvedere Castle.

It's only covered where buildings happen to cover it. It's not a tunnel
in any sense of the word.

Take a walk around the area. You can see (and smell) the traffic on the
expressway from the surrounding streets.

If it's in a tunnel, explain how I got these photographs:

Strictly speaking, if it's cut-and-cover, I don't think it's a tunnel.
In casual usage, I'd say it's generally not called a tunnel if the road
is covered by a single item or a distinct series of items, like other
roads or buildings, unless those items predate the road and weren't
removed to make way for the ROW underneath.

The Fort Point Channel portion (I-90) goes over the Red Line.
The "slay the green monster" portion (I-93) goes under the Red Line at
South Station, and there there are two underground levels above the Red
Line. I-93 also goes over the Blue Line.

I-70 in Colorado has two more double-bore tunnels. There is the Hanging Lake
Tunnel in Glenwood Canyon and another tunnel between Glenwood Springs and Grand
Junction, near De Beque, IIRC. I'm not sure what the name of the second one is,
and I also don't know what the official name is for the "Twin Tunnels" in Clear
Creek Canyon.

I-80 in Wyoming has a tunnel as well, near Green River, I think.

I-10 has a cut-and-cover tunnel in Phoenix, AZ.

Which leads me to another bit of conjecture:

Much as I-80 in Pennsylvania was originally proposed as a further
extension of the Turnpike System, Connecticut had originally planned to
complete the cross-state parkway (Merritt/Wilbur Cross) from
Massachusetts (Sturbridge) to New York on its own, but when the
Interstate System was laid out, reasons to complete the stretch that
would parallel or follow I-91 became moot.

There are three sets of tunnels in Glenwood Canyon: No Name, Hanging Lake,
and Reverse Curve (WB only). The twin-bore tunnel near De Beque is called
the Beavertail Tunnel in CDOT's structure list. The "Twin Tunnels" near
Idaho Springs don't have an official name in the CDOT list, but that's what
everyone calls them.

Has I-35 in downtown Duluth, MN been mentioned?

Doesn't I-10 have a tunnel in Mobile, AL also
