On that listing are some explanations of why traffic does some weird things on these circles, with strategies on how to reduce (non modded) or eliminate (modded) the impact of strange vehicle behavior on them, which helps to keep the traffic flowing quickly as originally when you started your city. If you’d like the start square’s traffic circle highway exit, you can find it here: Only the slope to the shoreline is steep but is still relatively smooth The terrain in the heart of the map has several different elevations of leveled land, with gradual, sloped transitions between each level for a natural look. See images here for instructions, you will find guideline walls for where to place the dam. It’s another vanilla map with a creative name! XD This one has a 25 square area that has some more variation in terrain than Vanilla Coast.
To build your hydro dam, click the dam function once on the end of one of the walls (super easy – the wall end snaps together with the dam end), then drag your cursor over to the other wall end (again, snaps for you), click again and done!
Electric production now between 600 & 700 MW. Authors description: 2019 Update: WAY more hydro power! Lots of fiddling with sea level, lake flow land and river.
