Signs covered in Vines

I bet you can't guess what sign this is for.  It is almost totally covered in vines.  Imagine trying to read it while driving.

Here's the same sign with a bit of road for context, does that help you figure it out?  Notice how the vines are covering the whole area, not just the sign.

Here is another sign nearby the first.  This one is a bit easier since you can read the word Lane, but which lane is it?

Need a hint?  The vines covering the signs are porcelain berry, an invasive  deciduous, woody, perennial climbing vine with flowers and tendrils that is often confused with plants from the grape species.  It has taken over this section of River Road in Bethesda, MD.

This sign isn't covered in vines, but it is a well-weathered Ride-On bus stop sign just around the corner on Wilson Lane, MD-188. (Does that give away the answer to what the above signs say?)
