CBenson wrote:Currently the U-turn roads are typically not typed as ramps here (because it conflicts with the wiki so they get changed when they are made ramps).

For example the [[At-grade connectors]] page says why to use ramps there so people understand the reason. In the U-turn page we just need to do the same thing to explain the "why." Part of the process of teaching people to fish.
Doesn't the U-turn page do that with the following:Road Type: RAMP
Although this departs from traditional rules for at-grade connectors and for use of the ramp road type, it hides the instructional street name in the client. It is close to the exception stated on the at-grade connector page, however, in that a MUTI is a signed--though unnumbered--exit from the current direction of travel on a roadway.
Otherwise, you get other workarounds like this segment.

Jughandles should be handled similarly, unless it is decided that they don't merit their own page; then we could just redirect "Jughandle(s)" to the AGC page. But this can be discussed with its own thread or in the general AGC page thread that's active right now.

FWIW, Wikipedia uses "Superstreet" for the RCUT page name, and "Michigan left" for the MUTI page name. I really wouldn't mind using both of those here... I had no trouble referring to Michigan lefts as such years before I ever went to Michigan. The abbreviations seem a little hypertechnical.
