Indeed, this needs to go down to all levels.  For example, Kansas has at
least one toll cycleway.

I'm curious how we'll handle this given the sheer number of route
shields.  Tulsa and Chicago have city highways.  Texas has 7 state
highway networks, in addition to county roads, US, and Interstate
highways.  Indian nations may or may not use the generic BIA highway
signs.  State cycleways often have nonstandard shields even when the
state has otherwise standardized on a state cycleway shield.  Major city
cycleways often have bizarre shields.
