This project will improve drainage capacity in this flood channel area of the Little Susitna River. This will involve clearing the right-of-way, elevating the surface of the road and deepening and widening the ditching on either side of the road.

The existing cross culverts also need to be enlarged to accommodate flood events.

After construction, rip rap will be added to stabilize the soil on road embankment sides and around the culvert to protect from fast flowing water.
