How can i add a degraded existing access road on Openstreetmap?

Recently I stayed at Anyiman a community at Gboko, Benue State, Nigeria. During my stay it was the rainy season and the street accessible to my residence was affected (degraded) due to the course of the rain. Guess what? it wasn’t even visible as a street on the map.
