How early do you guys start building traffic solutions? My first few towns (I usually realize I screwed up around that stage and start again) I just put down small roads everywhere, but lately I've been trying to plan ahead by putting down highways. This ended up screwing me over since the fire department couldn't figure out how to find the power plant. Is it best to just usurp the plot of land the highway is on and then use it as the central artery for traffic through your city? Should I wait until I can build highway ramps in order to avoid intersections on my big roads?
