road open to cars again at this point (going east), or closed to cars at this point (going west)

The signage isn't clear here. There are toilets with sinks but no sign saying clearly if it's potable water and there's no fountain.

Bike trail following the road here, up to intersection with the highway

Bike trail permanently closed. It seems like the route is not ready yet--theres no bike path or even sidewalk connecting with it beyond the bridge.

This toilet is actually much closer to the road, in front of not parallel to the pool.

There is a road here, curving left into the forest.

This bridge is closed to car traffic. It is a foot/cycle bridge only, and has only one lane. It is not a major street.
