Document Description
The purpose of the proposed project is to replace or repair 16 drainage systems that have deteriorated beyond their useful service life, located on State Route 3 in Trinity County. Culvert repair and replacement will protect the highway from stormwater runoff and erosion, and will reduce sediment discharges into the Trinity River and its tributaries. The project is needed to avoid roadway washout or more extensive roadway reconstruction due to failing culverts, maintain a safe-travel-way for the public, and remove any future threat to water quality.
