drainage grates

Roadside water inlets

Drainage grates are metal or plastic grids covering openings in streets, sidewalks, or floors that allow water to flow into drains while preventing debris and people from falling through.

They appear at curbs, in parking lots, and along roadways: Leaves clogged the drainage grate after the storm.

Cyclists and pedestrians watch for them because the slots can catch wheels or heels.
