Does this bridge still exist in 2025?

Pylons here have orange and blue blazes on them, and the capital letter H. Bass River SF is not supposed to have any marked trails, so what do these correspond to?

The Sand Paper reports that Circle Drive is closed to pedestrians and bicyclists but doesn't actually explain or photograph the new walkway/sidewalk, which is seemingly conflated with the existing sidewalk on the north side of the causeway.

Luby Loops has many more unmapped loops, especially in the area of this pin. Someone should very slowly roll them all with a GPS set to a very low tracking interval (1-2sec) and trace the GPX file. The paths are not deep enough to appear on the USGS 3D LIDAR layer.

The BTN trail has many more unmapped loops, especially in the area of this pin. Someone should very slowly roll them all with a GPS set to a very low tracking interval (1-2sec) and trace the GPX file. The paths are not deep enough to appear on the USGS 3D LIDAR layer.

These paths need GPS traces to be sure of their tracks and names. https://highbridge.org/wp-content/uploads/2020/07/Commons-Hiking-Biking-Trails-2020.pdf

Does the Five Bridges Trail cross the roadway here with a bridge or a level grade crossing? Street level images have not been photographed here since 2015.

When imagery updates, more details are needed here re: boom gate, one-way service roads in/out, fences, etc.

Can anyone provide any updates on this construction area?
