There could be a couple of reasons depending on what weight you are asking about. Some bridges use a counterweight mechanism to raise a section to allow boats under to pass. Some bridges might have a weight under the bridge to tune the frequency response of the bridge in a seismic or wind event.

Where is the center of gravity located on a bridge?
The center of gravity on a bridge typically lies at the centroid of the structure, where the weight of the bridge is evenly distributed. This is usually close to the mid-span. It is important to calculate and understand the location of the center of gravity to ensure the stability and safety of the bridge.
What is an inner bridge permit?
"Inner-Bridge" refers to the following: For the Interstate Highway System, inner-bridge legal weight limits are established.

The extreme axle distances for each of the two portions are both designated as inner-bridge limits. The inner-bridge for the truck tractor portion is the distance from the center of the steering axle to the center of the last truck tractor axle.
