I'm trying to add lane detail and relations to every US, Interstate, Turnpike and State highway in Oklahoma. My previous strategy seemed a bit too resource intensive (start at one end of a highway, work to the other, across the state). So I've basically restarted, and I'm going to focus one county at a time, in order of population. This should have the advantage of being "more right" for more people sooner than the relative scattergun approach of doing it by numerical order. That said, next up: Oklahoma County.
