The care and maintenance of sidewalks (including those along State maintained roadways) is the responsibility of the corresponding municipality. RIDOT maintenance responsibilities fall between curb to curb of the roadway. RIDOT will maintain state owned assets (such as catch basins) located within sidewalks. However, it is up to each municipality to maintain the surface and structure of sidewalks. Under State Statute (see below) maintenance and repair of sidewalks is the responsibility of the municipality, including keeping them clear of debris and brush.
For more information please see State Statute: Title 24 "Highways"
