The replacement of stream crossing has been a growing component of many DGLVR projects since program funding increased in 2014. The Program focuses funding on structures that are creating environmental impacts because they are undersized for the stream channel. Undersized structures create a variety of environmental and maintenace problems such as gravel deposition, excessive erosion, flooding, and creating a barrier to the movement of fish and other aquatic organisms. This page summarizes the policy and educational material available related to replacing a stream crossing to address these issues in PA’s DGLVR Program.
