I think a cousin of this would be rest areas or service plazas designed to serve both directions of the route, but with direct ramps. The new I-26 welcome center near Kingsport qualifies, as do an I-40 rest area in Tennessee between Lebanon and Cookeville, the Tamarack service plaza on the West Virginia Turnpike (which can also be accessed by local roads off of WV 3), and the Sideling Hill service plaza on the Pennsylvania Turnpike.
I'm a bit surprised there aren't more of these, but I guess it's cheaper to build two buildings than a bridge to make one facility accessible to both lanes.
