Texas style expressways

Conduit Boulevard in Queens.

Strictly speaking it is Conduit Avenue in Queens and becomes Conduit Boulevard when it crosses into Brooklyn (which is where the cross streets switch from having numbers to having names). But yes, that is probably the best example in the northeast, with the caveat that the freeway's odds of ever being finished are a lot lower than some of the Texas examples.

To one up that on the odds of freeway completion, though, try CT 34 in New Haven. Not only is there a segment that is a pair of frontage roads to an unbuilt freeway, this segment was actually made longer by removing a piece of the freeway that was built!

But then, most of the space between the frontage roads has since been developed, so on the ground it doesn't feel like driving on a frontage road anymore. The other examples named (including Conduit Ave in Queens) still have open space between the frontage roads.

Clyde Williams Blvd, Snellville GA. Presidential Circle is an eastbound frontage road; westbound is an extension of Tree Lane.

Clyde Williams Blvd, Snellville GA. Presidential Circle is an eastbound frontage road; westbound is an extension of Tree Lane.

That's odd. Are there plans for a freeway in the middle?

There were. At one point there was a scheme for a bypass for US 78 around Snellville. Accordingly, a very well connected developer bought a large parcel of land where the bypass would've crossed GA 124. No effort was made to protect the right of way, though, and the project was killed by public opposition before it ever really got going.

Clyde Williams Blvd was like the keystone in the arch-shaped bypass, of greatly diminished utility without the rest of the route. It came about mainly as a means of overpaying same developer way too much for his land, which was no longer viable as a mall site since the construction of Ronald Reagan Parkway linked the area to the existing Gwinnett Place Mall. Gwinnett County bought the right of way, though. 

The short freeway segment between Reagan and GA 124 had completed all the preliminary work and was grandfathered when the air quality conformity crisis hit in 1996, and it seemed certain to be built. However, some small design changes were made, and a public information meeting was held. Holding the public information meeting invalidated the previously-held public hearing, which invalidated the grandfathering conditions, thus putting the project on hold, eventually to be be abandoned. As an opponent of the project, it's hard for me to imagine that GDOT could've done something so clumsy by accident. I think we had an ally on the inside. But that's just my theory.

Was not Drumgoole Road in Staten Island built to have the current Korean War Vets Parkway in the median?

What about Bruckner Boulevard in The Bronx?  It is on both sides of the Bruckner Expressway which indicates that there either had to be a wide median for the freeway to be built or it was like Grand Concourse or Queens Boulevard where it is a 3-3-3-3 arterial that the center 6 lanes were upgraded.

No. The service roads were built at the same time as the parkway.

What about Bruckner Boulevard in The Bronx?  It is on both sides of the Bruckner Expressway which indicates that there either had to be a wide median for the freeway to be built or it was like Grand Concourse or Queens Boulevard where it is a 3-3-3-3 arterial that the center 6 lanes were upgraded.

Between the Sheridan and the Bruckner interchange it was 3-3-3-3 arterial and the inner "express" lanes were freewayized. East of the Bruckner interchange it was narrower and the freeway was shoehorned in by condemning adjacent properties.

West of the Sheridan, of course, it's entirely elevated and the original footprint of Bruckner Blvd is preserved albeit not in its original configuration.

US 90 Business in LA where the route is still arterial.  It has the wide median for the future West Bank Expressway Freeway extension that will someday be I-49.

Also the existing US 90 B freeway was built in a wide grassy median of the original West Bank Expressway except at the Harvey Tunnel where the two carriageways came (and still come) together.

Yes US 90 Business was for seen as a future freeway corridor when built many decades ago.

Between the western terminus of the Westbank Expy. at US 90 and Segnette Blvd, though, US 90B is more of a traditional 4-lane divided arterial; the median doesn't widen to a "Texas expressway" standard until Wayne Avenue. Also, there's that funky "folded diamond" interchange with US 90 where two ramps cross each other at grade.

Fortunately, all that will be fixed as part of the interim improvements planned as part of the I-49 South upgrade. The median will be widened all the way to US 90 to accommodate the future I-49 mainlanes, and a flyover ramp will replace one of the crossing lanes.
