I'd like to take just a moment to complain about one of the thousands of annoying things about driving in Austin: if you are on westbound Braker Ln and want to go south on Mopac, you make your left turn where Braker crosses Mopac, and then drive south on the feeder road, expecting to find a ramp that will let you get on Mopac, which is literally just a few feet to the left of you. But you keep driving, and there's no onramp. You keep driving, and there's still no onramp. You come to a traffic light for 360, which you have to wait through. Then, just up ahead, finally the ramp you've been waiting for! Instinctively, you take it, and realize a second too late that Aw fuck, this ramp goes to 183S, not Mopac.
Yeah, admittedly there is a sign that says 183 for that ramp, but it still seems very strange to me that it wasn't designed to have the Mopac ramp first and the 183 ramp further down the road.
