Editing Diamond interchange (section)

===Other===
Where [[HOV lane]]s are present for [[carpool]]ing, the ramps of a diamond interchange may be folded to the inside lanes instead of the outside. In [[urban area|urban]] areas this saves some space as well as requiring only one intersection instead of the two one-way intersections, which in [[rural area|rural]] or [[suburban area]]s can be turned into a [[single-point urban interchange]]. This in turn reduces waiting time for motorists at [[traffic light]]s on the smaller road, which may be a large local [[thoroughfare]] with heavy traffic.

In [[Henrietta, New York]], Jefferson Road ([[New York State Route 252|NY-252]]) crosses West Henrietta Road ([[New York State Route 15|NY-15]]) on a modified diamond interchange, where traffic merges onto NY-252 at signalized intersections without any merge lanes, as well as [[Texas U-turn]]s and [[Right-in/right-out|RIROs]] on the ramps.
