BUT: Even though the urban frontage roads in Texas, Oklahoma, and a few other states are major roads in and of themselves, worthy of being called primary street due to their heavy use, should they be considered as part of the "primary road" type selected for long-distance routing?
Having lived in Houston for some time, I would say yes, for sure. If traffic is bad on the main road, as it often is, it's sometimes faster to drive along the frontage road. At least it certainly felt that way!

Please feel free to delete those. Since it's usually illegal for drivers to use them, and because anyone getting driving instructions that uses them will think Waze is clueless, it's best to eliminate the possibility of a route including any of those segments.
