PROJECT BENEFITS
- Constructing a new bridge parallel and west of the current structure design and seismic safety standards.
- Realigning the highway approaching the bridge on both ends.
- Constructing the new bridge to accommodate five lanes in the future.
- The new bridge will be striped for two lanes and provide for 8-foot paved shoulders, sidewalks on both sides and a concrete barrier separating the shoulder from the sidewalk and bridge railing.
- Two traffic lanes will remain open throughout construction. The old bridge will be demolished after the new structure is completed.
