Re: How to extrude a road segment?
Thanks for the feedback.
What I ended up trying was made a rectangle road segment and textured it. Then used the replicator like you said, and set it on duplicate not extrude. I made the long straight away with that, and for the curves, I just duplicated a single road segment and rotated it X degrees, snapped the vertice of the road segment to the existing piece, and repeated for a turn. I could have used alot more road segments to make a really smooth road, but I need to keep poly count low for collision in game. After the road was done, I merged all objects and welded the vertice so there were no duplicates. Here's some pics of what it turned out like.
