US cities with tunnels (mover, dangerous, vs)

[tarheel84]

Providence has two tunnels. One is an old trolley tunnel built because of the steep incline in college hill. Buses still use the tunnel. The other tunnel is a closed off railroad tunnel under the east side.

Pittsburgh has the Armstrong Tunnel is downtown Pittsburgh. This tunnel burrows beneath Duquesne University and connects to the 10th Street Bridge. The Armstrong Tunnel has a cool curve.

More highway tunnels than NY/NJ, yes.
NY/NJ: 4 (Holland, Lincoln, Brooklyn-Battery, Queens-Midtown)
Tidewater: 6 (Downtown, Midtown, HRBT, MMBT, CBBT Thimble Shoal Tunnel, CBBT Chesapeake Channel Tunnel)

If you count rail tunnels, NY/NJ goes up by a pretty big margin.

I think might have been aware of that. Wasn't there some sort of light rail system designed to connect downtown Cincinnati with Covington across the river the was going to use this infrastructure?

StL uses a portion of abandoned tunnels in the downtown area for Metrolink.

Longest one in the SF Bay Area is probably the Caldecott Tunnel that cuts through the East Bay hills. The temps can vary as much as 20 degrees on either side of the tunnel due to microclimates.

Couple of other ones in the area not mentioned:
Wesbter and Posey Tubes connecting Oakland and Alameda:

Robin Williams Tunnel just before/after Golden Gate Bridge:

Baker-Barry Tunnel right next to Robin Williams Tunnel/GGB. It's only one lane so the tunnel has to clear before traffic in opposite direction is allowed to pass through:

Yeah two of Pittsburgh's tunnels have to be competing for Spookiest Tunnel. The Armstrong tunnel and the Wabash tunnel. Also competing with the Baker-Barry tunnel in SF. Also with the Spring Garden St. tunnel in Philadelphia, I don't think that one's been mentioned yet.

Cool, I'll check it out next time I'm in the Burgh. Looks like maybe a pair of old trolley tunnels?

Interesting, I used to think there was no road tunnels in Chicago before clicking the link and then I went back into map mode and found that Chicago has on-ramps, exit ramps, turns, streets, four-way stops that are "indoor"/underground.

San Diego.

Plenty of smuggling tunnels under the border with Tijuana, Mexico.
