Collapsing culverts mar roadways

State says 30 percent of tunnels are failing under highways.

They lie underneath roads, unseen to the naked eye and disregarded by those who drive above. But when culverts fail, they can cause an abundance of issues for drivers on state highways.

The state Department of Transportation estimates that 30 percent of culverts under highways in northwest Oregon are in poor or failing condition, and efforts to replace them before they fail have accelerated in recent years.
