Title: Collector-distributor lanes not on freeway, expressway, or parkway
Post by: dgolub on August 25, 2013, 11:09:20 AM
A couple of months ago, I was travelling on US 9 in New Jersey and came across collector-distributor lanes, which I thought was interesting because US 9 is not a freeway, expressway, or parkway in the area.  I've never seen that anywhere else before.  Does anyone know of any other places where it happens?

There are a few sets of them on Santa Monica Blvd just east of the 405. (Street View example (https://www.google.com/maps/preview#!data=!1m8!1m3!1d3!2d-118.443242!3d34.047889!2m2!1f78.47!2f90.27!4f75!2m4!1e1!2m2!1sg5WkfN_QDWSEcdBI2XeIyA!2e0&fid=5))

That looks more like a service road to a local street.  Here, in New York, there are a few places where that exists in Queens, most notably on Queens Boulevard (NY 25).  However, what I saw in New Jersey on US 9 was a grade-separated interchange with collector/distributor lanes on a road that was not a freeway.

US 9 is a Jersey expressway there.

They exist on Comm Ave, among other roads in Boston.

What about Roosevelt Boulevard in Philadelphia?

Loch Raven Boulevard (MD-542) in Baltimore County, MD has them, so does Cottage Grove Road (CT-218) in Bloomfield, CT.

I take you are referring to the US 9/ CR 516 interchange in Old Bridge Township?  You have on the NB side c/d lanes because also Throckmorton Lane/ Ticetown Road have an interchange directly to the south of it, so to prevent weaving it was necessary to do so.

Oh hell, there are a whole bunch of roads in New York City with a inner/outer roadway setup for at least part of their length. Let's see:

Grand Concourse
Pelham Parkway
Mosholu Parkway
Queens Boulevard
Woodhaven Boulevard
Linden Boulevard
Kings Highway
Ocean Parkway
Eastern Parkway
Adams Street

Then you have Bruckner Boulevard, Van Wyck Boulevard, and Horace Harding Boulevard which historically were like this until their inner roadways were converted to freeways.

There's a name for the type of road in many of these examples: multiway boulevard.  In fact, there's a whole book about them:

The Grand Concourse, Ocean Parkway, Eastern Parkway, and many others from around the world are discussed in great detail in that book.
