What is the primary function of a drainage system on a bridge deck?

Explanation:
The primary purpose of a bridge deck drainage system is to remove rainwater quickly from the surface so it doesn’t pond or flow into traffic lanes or gutters. By collecting water into drains, scuppers, or gutters and directing it away, the surface stays dry, which helps maintain traction, reduces the potential for ice formation, and protects the deck from water-related damage over time. Other features like lighting, structural support, or aesthetics serve different functions and aren’t the primary purpose of drainage.
