The Holy Grails of Roadgeekdom

That interchange in New Orleans between two freeways (well at least the interchange is completely free flow grade separated) that has the roundabout in it. I believe it is between the Airline Highway (US 61) and South Causeway Blvd.

The Astoria-Megler Bridge (US-101 WA/OR)
The floating bridges in Seattle (I-90, WA-520)

Aside from the impressive view from the [acid] rock cuts on Skytop, there really isn't anything special about I-99.

I'd add Centralia, with the abandoned section of PA 61, to the list.

[getemngo]

I'd add Centralia, with the abandoned section of PA 61, to the list.

In that case, I'll add the abandoned PA Turnpike to the list.

I'd add Centralia, with the abandoned section of PA 61, to the list.

In that case, I'll add the abandoned PA Turnpike to the list.   

I figured that was included under "Breezewood."

Lake Pontchartrain Causeway - Saw it on History (Channel). Very cool looking.
Hive Five Interchange - Outstandingly cool interchange. Saw it on History (Channel), too.
I-10 & I-20 (West Texas) - 80 m.p.h. legal speed limit
I-15 (Utah) - 80 m.p.h. legal speed limit


Be well,

The George Washington Bridge and its approaches.
Any major highway in New York City, but especially the FDR Drive, the Cross Bronx, and the Gowanus/BQE.

The trick is getting through those without hitting too much traffic!

(Protip: do the Cross Bronx eastbound, not westbound)

[SSOWorld]

actually the Kennedy Expressway - where all the exits and entrances are within 500 feet of each other.
Seney Stretch in UP Michigan (M-28)
The Loneliest Road
Extraterrestrial Highway

[FLRoads]

I would have to add the Sunshine Skyway bridge between St. Petersburg and Palmetto, Florida to the list. It was the first cable-stayed bridge constructed in the U.S. and one of the highest vertical clearances in the southeast (being 200 feet from water to bridge deck).

New River Gorge Bridge

[Alex]

Was thinking about this last night, a few things on a national level that I think merit seeing by any road enthusiast:

The New Jersey Turnpike's four-carriageway section
Interstate 70 through Glenwood Canyon
The stack interchange between Interstates 105 and 110

[Hellfighter]

I would have to say the Pacific Cost Highway

[Truvelo]

Considering I'm not from North America I can say that I've visited four of the locations already mentioned in this thread:
# Breezewood (PA)
# I-99 (PA)
# wrong way section of I-8 (AZ)
# George Washington Bridge

I will probably see some of the others in future visits

[Sykotyk]

Some other ones:

Wallace, ID (elevated I-90, last stoplight on I-90 located in town, it also is self-professed to the be the center of the universe, with a manhole cover marking the location (I'm serious,....))

Zanesville, OH (Y-Bridge on the National Road, now I-40)
New Orleans, LA (Lake Ponchartrain Causeway)
Louisiana: I-10 between Baton Rouge and Lafayette: 18-mile long bridge)

The Turnpikes of Oklahoma (especially the Cherokee and Chickasaw)

Those are mine, plus hundreds more.

One more from me:

Chain of Rocks Bridge, the bridge with an angle in the middle that used to carry US 66 between Illinois and Missouri.

I-275 around Cincinnati - clinch 4 states in 10 minutes

I-275 around Cincinnati - clinch 4 states in 10 minutes

Ohio, Indiana, Kentucky... Which one is the fourth?

Same question I have. lol.

Maybe he means Counties?

I'm not talking about things an average tourist might want to see, like the Golden Gate Bridge or a scenic route, but attractions that would probably only be sought out specifically because someone in the car is a roadgeek.

US 1 from Florida City to Key West.

Given Scott5114's criteria, US 1 to Key West does not qualify.  It is not just of interest to Roadgeeks but to Railfans as well.  The original bridges of the highway of which some survive as Fishing Piers, etc. were constructed by the Florida East Coast Railroad in the 1920s.  They were converted to highway use after the FEC abandoned the route after a hurricane.

My 840th post!  (See avatar!)

The old Lincoln Highway in Ohio paved in red brick.

I guess I lost count

Speaking of the Arroyo Seco...the Four-Level Interchange between Route 110 and US 101 (also formerly containing portions of US 6 and US 66) has to be an obvious candidate for a visit, being the very first of its kind.

Isn't the first ever cloverleaf (if it still exists) in New Jersey?

[Bryant5493]

I'd like to add the Cobb Cloverleaf, Spaghetti Junction/Tom Moreland Interchange and the Wayne Shackleford Interchange/I-85 @ S.R. 316 to the list. They are impressive interchanges.


Be well,

You can see the history of the Overseas Highway on an episode of Modern Marvels.  I found it very interesting.
