crowd of people on motorcycles congregated on a steel truss bridge

crowd of people on motorcycles congregated on a steel truss bridge. The camera appears to be positioned on the bridge, looking down the length of the structure. The bridge has a metal frame with a lattice-like pattern of steel beams overhead. People on motorcycles are in the foreground and extend into the background. Many of the riders are wearing helmets, and some passengers are wearing headscarves. There is a yellow triangular warning sign at the front of the frame. The sky is overcast, and in the distance, trees can be seen on either side of the river the bridge spans. The road surface of the bridge appears to be gravel.
