I had the boardwalk between the house and the summer cottage replaced, but with twist - literally: both ends of the boardwalk now gently rise up and meet the house’s backdoor and the cottage’s front porch level, so there are no steps anywhere. Also, it’s wider than regular, commercial boardwalks. You could say it’s a boardwalk with accessibility in mind.
My wife who has a disability can now easily go to the cottage and spend some time enjoying the lake and listening to music there without any help.
Not rain, no. The wood is new, it’s treated and it’s slightly corrugated. The old boardwalk’s wood was smooth as a baby’s bottom after 40 years outside, and slightly covered in moss that would turn slimy in the rain - which is half the reason I replaced it: it tried to kill me once too often 🙂
As for snow, it’s not slippery as long as it’s dry. Once it’s wet and melty, everything is slippery 🙂
