Few drivers zipping along Northwoods roads probably think about the culverts they cross, culverts sending stream water underneath the pavement or gravel.
Instead, it’s Jon Simonsen’s job to worry about the structures, which play a major role in both transportation and fish habitat.
“People don’t give a culvert much thought, and they’ll pass over it. But they think about it a lot when the road is washed out and the road has failed,” said Simonsen, a DNR transportation liaison. “So that’s when it has become significant.”
