this is where you catch buses. it's one lane/one way. its underground obviously, might edit it a bit more, make a turn-off so express buses can ignore a stop, and overtake parked buses. lighting probably needs work, maybe the scale of those concrete pillars/beams.
didn't include the only custom dx class i've made so far; pawn transit.authority, love those guys, didn't want to spoil the surprise (ie. i f***ed up there shirt texture so they look shit, i'll figure it out eventually- lol)
hmmm can't think of anything else to say, some ideas could be helpful obviously ;)
