Document Description
Project proposes to widen SR 121 over Huichica Creek, remove the existing triple metal culvert (Bridge No. 21-0001), replace it with a free span bridge, and incorporate fish passage improvements and creek bed restoration along approx 400 ft of Huichica Creek. This proposed widening will not increase the vehicular capacity of SR 121. The purposes of this project are to reduce the potential for cross-centerline and run off the road accidents on SR 121, provide continuity to the widening of SR 121 constructed on a previous project (Duhig Roadway and Rehabilitation), and satisfy regulatory fish passage requirements.
