摘要
A system providing environmentally friendly pathway tunnel utilizes bridge units having a bottom configuration with multiple elongated beams and slots. One or more of the beams includes upstanding sedimentation members that are spaced apart along a span of the tunnel. The system interacts with the flowing water and earthen material in the flowing water such that capture and settling of the earthen material at locations along the tunnel occurs to produce a more natural water flow pathway along the tunnel.
