Non-freeway flyovers
« on: January 24, 2019, 08:37:41 PM »

I saw one today at the US 1/601 split in Lugoff, SC. Got me thinking about others that may exist.

A1A and FL 907 in Miami Beach.

It always felt to me as if it belonged in a pinball game.

Not sure if it counts (connects a non-expressway to a connector for an Interstate), but the CT-32 North to I-395 North Connector ramp in Waterford CT: https://www.google.com/maps/@41.4181372,-72.110249,705m/data=!3m1!1e3

Also not sure if this counts (DE-1 is kinda-sorta an expressway here but not really), DE-1 at US-113 in Milford DE: https://www.google.com/maps/@38.9379694,-75.4302102,1039m/data=!3m1!1e3

And again not sure if it counts (US-50 and MD-90 are kida-sorta expressways but not really), US-50 at MD-90 near Ocean Pines MD: https://www.google.com/maps/@38.3697917,-75.2720986,742m/data=!3m1!1e3

Here's also the Fairmount Park Interchange in Philadelphia: https://www.google.com/maps/@40.0129668,-75.2044502,510m/data=!3m1!1e3

US 189 and UT 52 is the only Utah one that jumps out at me.

Two stick out to me.

The overpass between 15th St SW and the Supermall in Auburn, WA: http://bit.ly/2CK3fVP

The other is London's infamously narrow Hogarth Flyover, built as a temporary measure in the 70s, but kept after Ringways was abandoned: http://bit.ly/2sTEBxz

US 301 south has a flyover across MD 5 north of Waldorf, just to the south of the new interchange being built at MD 373.

MD 24 has an overpass at MD 924 Tollgate Road, just west of I-95 in Harford County. MD 24 is an expressway in both directions.

MD 258 and MD 260 both terminate at MD 4 in Anne Arundel County and each terminus incorporates a flyover for traffic from MD 4 south, which only becomes a freeway west of MD 258.

US 50 westbound flies over US 301 to join the latter highway. However, both routes are freeway-grade west of here and US 301 is freeway-grade for a short distance to the north, so this might not count.

A few come to mind:

Western PA in particular has a lot of these flyovers and quirky proto-interchanges, likely due to a combination of the hills and population density.  In fact, it may make sense to tighten the definition further, to rule out anything that looks like a fully grade-separated interchange.  Similarly, does the Park Avenue flyover by Grand Central Station in Manhattan count?

There are a lot of bridge approaches and trumpets that technically qualify, but I don't think are the intent of the post, such as US 11/15 and PA 61 in Shamokin Dam.

Seems to be a thing on A1A. Here's another one a bit to the north at FL 826. And another one at FL 858.

Here's a "fly-under" at CA 49/108 in Sonora: https://goo.gl/maps/dLaQ1xb7ZWk

Neither route is a freeway or expressway at this point, though CA 108 does become a super-2 (with an at-grade and a few interchanges) to the east.

What is the point of this flyover? Neither route is particularly busy.

(Fixed your link.)

Charlesgate is just an overpass, nothing special there.  But at its interchange with Storrow Dr, the north-to-west movement could be considered a flyover.  However, Storrow Dr at that point is fairly freeway-ish.

KY-645 is a four-lane highway, so it's not completely out of place.  But it's a great example nonetheless.

To my eyes, that's just a three-way interchange.  Plenty of non-freeway examples of that out there;  I can think of several off the top of my head in Texas.

Oddly enough that interchange at FL 50/520 has four movements despite both being expressways.  The only movement on that flyover is FL 520 west to FL 50 west.  In the example I gave regarding CA 152 and CA 156 only three movements are available.  Traffic wanting to go from CA 156 east to CA 152 have to exit on Casa de Fruita Parkway and U-turn.
