Roadways below auto viaducts

[index]

These always have really neat looks to them and most of them seem to be going away in favor of more up-to-date engineering.

The viaduct over the one on I-70 in Denver is slated for removal with the Central 70 project, and the Alaskan Way is pretty much long gone now.

Central 70:

There is a section of the NY 17 'old' road that runs under a viaduct part of I-86 in upstate New York, too.

Hawaii's Interstate H-3 is on a viaduct through the scenic Halawa Valley. Underneath that viaduct is an access road, built for construction of the viaduct. It starts at the back of an HDOT maintenance yard, and is not open to the general public. AIUI, HDOT occasionally allows travel on the access road (mainly by native Hawaiian organizations) such as to visit religious and cultural sites in the valley.

Part of the access road, visible from the H-3 viaduct, can be seen in the lower right corner of this photo:

Division Street in San Francisco runs directly underneath the Central Freeway/US 101.  Interesting vibe, though there are spots where homeless encampments have been established (which does occur in quite a few underneath-freeway areas in South of Market)

The I-5 Express Lanes are under both directions of I-5 at different points at the Washington State Convention Center to Mercer St.


The eastside approaches for the Hawthorne and Morrison bridges, all retain roadways underneath for local access.


HI 92/Nimitz Highway as well as HI 99/Kamehameha Highway travel together underneath the H-1 Freeway on the North Side of the Honolulu Airport

HI 92/Nimitz Highway as well as HI 99/Kamehameha Highway travel together underneath the H-1 Freeway on the North Side of the Honolulu Airport

Just 92/Nimitz. HI 99 ends at the west end of the viaduct.

A short remnant of the Kamehameha Highway exists east of the east end of the viaduct, as unsigned HI 7401. Before construction of the H-1 viaduct, the six-lane divided Kamehameha Highway and the four-lane undivided Nimitz Highway ran in parallel north of the airport (1951 photo, courtesy of Hawaii DOT). As part of the viaduct project, those highways were merged into a single divided highway under the viaduct.

EDIT: Forgot about another road under a viaduct, near the east end of H-1 -- part of Waialae Avenue runs for about a half-mile under the freeway:

Two more not mentioned yet:

- In Kansas City, there are two levels to the W 12th St viaduct west of downtown.  The lower level connects to Beardsley Rd east of the tracks and to Hickory St in the West Bottoms.

- In St. Johnsbury, VT, Memorial Bridge (US 2 over the railroad and the Passumpsic River) has a lower level with the streetname of Weeks Ct, which connects to Bay St and River Rd.

Several downtown streets are under I-794 in MKE.

In a similar fashion, here is E Ave NW under I-380 in Cedar Rapids.

Underneath Boston's old Central Artery, pre-Big-Dig, from roughly the Rowe's Wharf area (just south of the New England Aquarium) to the Callahan Tunnel interchange was a parallel street named either Surface St. or Surface Artery

[jay8g]

the Alaskan Way is pretty much long gone now.

Ha, I wish! Hopefully in another couple months or so.

Seattle does still have a few "live" examples though.

• S Spokane St under the Spokane St Viaduct (interestingly, the original Spokane St Viaduct only sat over the median, but the 2000s expansion widened it to be over the westbound lanes as well).
• Across the Duwamish, SW Spokane St under the Fauntleroy Expressway
• Royal Brougham Way under the west end of I-90 (which is itself a double-decker viaduct in this section, which I suspect was originally designed as such with the intention of connecting up to the AWV through what was referred to as the Connecticut Street Viaduct, which was never built)

[jakeroot]

The Front Street Parkade in New Westminster, BC, sits on top of Front Street. Technically a viaduct, I believe.

Seen in such films as I, Robot (Will Smith running after robot with the purse), and Godzilla (2014 -- abandoned city of Janjira).

Partly demolished a few years ago, other half still standing. No plans to take down the rest.

Part of me is tempted to say Upper Wacker Drive and Lower Wacker Drive in Chicago, but not quite sure if Upper Wacker really qualifies as a Viaduct, as it is Street-Level

The 'lower' level streets in that area are the original street level, those 'upper' level streets were first built above them over a century ago to make it easier for freight services to get to the buildings' docks without mucking up other street traffic.  Pretty ingenious, IMHO.

Thanks for the clarification.  Just just assumed the designations continued on both ends due to the roadway splitting at each end.  I find it a fascinating piece of engineering, and it is actually an interesting walk and drive.

Third Avenue under I-278 in Brooklyn, NY:

Some of River Rd in downtown Louisville runs under I-64.

[roadman65]

The LIE in Queens east of the BQE has the long ramps from I-278 to I-49 coming from and going to I-495 underneath it.  I also believe the BQE north of the LIE has a local street underneath it.

There is a viaduct in Kansas City that has another local street under it.  Can't remember where, but me and another user on here captured (or captioned)it in photos back in 2016.

[kphoger]

Do we count double-decker expressways, such as those in Austin, Mexico City, Puebla... ?
