There are several types of bridge drainage systems, including:
1. Grated bridge deck drains: These are typically installed at regular intervals along a bridge deck and are designed to collect and convey surface runoff from the deck.
2. Scupper drains: These are openings located at the edges of a bridge deck that allow water to flow off and down to a lower level.
3. Inlets: These are drainage structures installed at bridge abutments to collect and convey water from the surrounding area.
4. Trench drains: These are linear drains installed in a trench beneath the bridge deck to collect and convey water horizontally.
5. Sump pumps: These are installed within a sump located beneath the bridge deck to pump water out of the sump and away from the bridge structure.
6. Downspouts: These are pipes that are attached to the underside of the bridge deck to collect and convey water down to the ground.
