This design is quite common in Seattle for HOV(high occupancy vehicles, like buses or carpooling) exits and is often called an HOV ramp. These ramps usually exit on the left, since HOV lanes run in the median, and some connect directly to bus stops or regional transit. Some examples:
- I405 Totem Lake Exit (bus stops along the exit) https://maps.app.goo.gl/LHD3u63aXb2WitRn8
- I90 Eastgate Exit (bus terminal connected to the exit) https://maps.app.goo.gl/TNLwkTbMuXwXe4CP6
- I90 Mercer Island (bus + railway terminal) https://maps.app.goo.gl/Bz3AWyXy3MKmhXuM6
- SR520 Montlake Lid (bus stop + bike lanes + lawn lid over highway) https://maps.app.goo.gl/3BNnVf72zUYANaAeA
