The oft-photographed and written about interchange on Interstate 70 between the free section, US 30 Lincoln Highway and the very much not-free-section of Pennsylvania Turnpike. Interesting to zoom in and explore the various businesses along the way.
The Butternut Interchange, where I-690 connects with Interstate 481 in the town of DeWitt, includes a pair of unused ramps and grading for additional connections with the unconstructed relocation of New York State Route 5. A 1965 proposal for a bypass of Fayetteville outlined a corridor extending southeast from I-690 and then I-281 along the right of way of the New York Central Railroad, Chenango branch to Route 92 at point near Oran.9 The Fayetteville Bypass was advanced by state officials at a luncheon on March 17, 1967, but without a tentative timetable. Coupled with a proposal to relocate Route 92 to the south of Manluis, the realignment of Route 5 was roughly projected to follow the old Erie Canal east.10 Ultimately neither Route 5, nor the four to six lane highway envisioned for Route 92 east from the Jamesville interchange with I-481 were constructed.

While those are interesting connections how they are hooked into the interchange, I could see how this could become a weaving problem.
This is a set directional "T" interchanges, however not all connections were made with this superhighway. This will change when they take down the Syracuse Viaduct over the next few years.
I've always been impressed by the size of this interchange and the long abandoned but still remaining connections to Crouse Road.
A couple of trumpets and ramps designed to favor US 9 to Interstate 90.
The Bennington Welcome Center is located within the interchange between US 7 and VT 9 - VT 279. At one point this was going to be Interstate 88, which would extend to Maine but that road was canceled decades ago.
