I have been tasked with finding a solution
to a slick bridge problem. Hoping someone else has some
expierence.
Our local park, has a multi-use trail (hikers,
bikers, horses), the land here is very low and the trails border a lake.
There are quite a few muddy or wet spots (the sink to your knees type) that have
been covered with treated wooden boardwalks and bridges. About half of
these bridges are fine, they get plenty sunlight and are only slick in the
rain. The over half, hardly ever see sunlight, and quickly get green
slick slime layers coating them. The bikers are fine, walkers have a
little trouble, for the horses its just dangerous.
Ideas presented:
*Power wash them -- too
short term solution
*Grip strips like on
stairs -- I don't feel they would last, they wear slick pretty quickly
just with humans in tennis shoes
*Grip paint - again, will it
really hold up with horses in steel shoes?
*Thin wooden strips
-- it would work for us, but how would the bikers like it? (anyone
mountain bike?)
*Fine gravel or sand
- this so far sounds to be the best idea
Removing or replacing these bridges is out, most
are new, and there's about 30 total. Also there is an access problem, the
trails are just wide enough for an ATV or small tractor. (single tract for
horses)
