That sounds similar to an area around the freeway I traveled through two days ago. They kept one lane open, one for each direction of the freeway, but the middle area had to be closed off because there's this small slope. They were building wooden fences/barriers to prevent the mud from coming down the slopes.

I think it would have been scary to be on the overpass when/if it collapses Dx
