The type of vehicles and traffic that a bridge currently supports can vary greatly depending on its design and location. Here are some insights from recent findings:

1. Manhattan Bridge: This bridge supports seven lanes of vehicular traffic, four transit train lines, a pedestrian walkway, and a separate bikeway. It accommodates over 70,000 vehicles, 3,000 pedestrians, and 6,000 cyclists each day source.

2. Brooklyn Bridge: It features five lanes for vehicles (excluding trucks) and provides a pedestrian promenade along with a protected bicycle path. Daily, it carries over 107,000 vehicles, 32,000 pedestrians, and 4,000 cyclists source.

3. Brent Spence Bridge: Originally built for about 80,000 to 100,000 cars per day, it now supports between 160,000 to 180,000 vehicles daily, exceeding its original capacity source.

In general, vehicular bridges are designed to support the weight and flow of various vehicle types, including cars, trucks, and buses, and may also facilitate pedestrian and cyclist traffic. If you have a specific bridge in mind, please let me know for more detailed information.
