Took a spill on my bike on this bridge when is was wet, going straight and slow. This is a problem on all the bridges in this area. They're very shaded and get moldy and slippery. I passed someone who had just taken a spill on the next bridge near the Wetland center, and I took a spill on the bridge/walkway before this. They're even dangerous to walk on they're so slippery.

Maybe there can be some texturing done to these boards or some type of adhesive with grit in it?
