Development of Low-Water Crossing Design Guidelines for Very Low ADT Routes in Illinois

The main objective of this research is to develop guidelines that can be used to determine optimal safe and cost effective low-water crossing (LWC) design to meet traffic needs, maintain the natural channel function, and permit water, sediment, debris, and wildlife free passage for aquatic organism passage (AOP). This research project will assist Illinois Department of Transportation (IDOT) and local agencies in determining safe, cost-effective, and environmentally friendly design of LWCs for low average daily traffic (ADT) routes in the state. In addition to the geomorphic, biological and engineering considerations at each crossing, this research will also take into account the upstream watershed conditions such as land use/land cover, topography, and soil conditions, which, as a whole, will determine discharges and high-water elevations.
