The interchange: As is clearly evident from the photo, this interchange began life as a "trumpet" interchange. From 1935 until 1956, this was the northern terminus of the Meadowbrook Parkway. When the parkway was extended northward, new connections had to be built, and the existing configuration was altered only slightly to accomodate them. In fact, many of the interchanges on the Long Island parkways have similar histories, but while some have been completely rebuilt in recent years, a few older forms still remain, like this example. Nevertheless, this interchange is scheduled for complete reconstruction after 2004.

As it stands today, the configuration is that of a full cloverleaf, with the northbound-to-westbound ramp "unfolded" into a left-hand exit (considered undesirable by today's standards). In addition, the two southbound entrance ramps join each other before merging into the mainline. Other ramps have been rebuilt to provide a greater turning radius, most notably the westbound entrance ramp at the "head" of the original trumpet. Notice that the ramp's original position is still clearly visible here; a few other vestigial traces of the old ramps can be seen as well.
