Road ecology blog: Drainage system for run-off at multifunctional underpass, under A4 motorway, Parndorf, Austria.
Run-off from roads may contain pollutants from the pavement itself, the tires from the vehicles, deposits from exhaust, and sand, salt or other deicers. Here the run-off is collected by a drainage system and directed to the sides of the underpass.
