Existing road and bridge within County right of way, adjacent properties zoned LIA (Land Intensive Agriculture), currently planted with grapevines.
Document Description
The proposed project would replace the Wohler Road Bridge over Mark West Creek in lieu of a seismic retrofit. Replacement was determined to be the best alternative because the existing roadway has a sharp curve at the north end of the bridge which limits sight distance. The project would move the crossing east (upstream) about 100 feet from the north end and 60 feet upstream from the south end of the existing bridge to cross the creek at an angle and allow for safe sight distance on the new bridge. The new bridge would consist of a 3-span concrete slab supported by two solid wall concrete piers that are centered in the main portion of the creek channel. A small amount of new approach roadway would be constructed to join the new bridge with the existing roadway. The existing bridge would remain open until the replacement bridge is completed, at which time the old bridge would be removed. New right of way will need to be acquired from adjacent parcels.
