Portland, Oregon
There are quite a few maps for Portland, and after looking at most of them I was disappointed with the highways and interchanges. This one is by no means perfect, but the main interchanges should feel more accurate. I focused on I5, I405, I84, and US26(west connection, the Ross Island bridge is yours to build). The map itself is slightly out of scale relative to the size of of the games’ building and zoning sizes. I also have not renamed all the highways to their real names so you’ll have to do that in-game, sorry.
