A safety end treatment is a concrete structure at the end of culverts or storm water pipes installed under roadways. Extensive testing has proven vehicles that leave the roadway will safely cross the end treatment instead of crashing into the end of an otherwise exposed culvert or drain pipe. The cross-pipes are a safety feature that help a vehicle safely go over the culvert or pipe end.
