>>1794014they put a diverging diamond in my city to replace an existing intersection; originally it was a four lane highway overpassing a four lane surface road with stoplights at the on/offramps. they left the highway overpass as is and changed the surface road to a diverging diamond.
it has asymmetrical on/offramps but works fuckin great, it used to back up all the time but now never has any traffic delays even at rush hour. only drawback imo is the effect high traffic volume flowing constantly has on nearby intersections and minor access points
