SUMMARY OF PROJECT•Piers (2-column supports): Rehabilitate the external surface concrete
•Facade: Rehabilitate the external surface concrete that is visible to the public & Install new steel doors at all columns
•Soffit: Rehabilitate the external surface concrete on the undersides of the bridge
•Piers (2 column supports): Retrofit the internal column section by adding shotcreted shear walls – additional 10” of thickness
•Entire Superstructure: Retrofit by installing post tensioning, steel shear pipes and new concrete to restrain the mid-span joints

•Footings (Interior): To remain undisturbed. Tests show sufficient soil bearing capacity even under extreme loading
•Footings (Exterior): Install accent lighting
•Abutments Structural Elements and other: Rehabilitate the internal concrete, grade soil and install ladders and walkways
•Abutment Facade: Rehabilitate external surface concrete, install temporary and permanent doors, reroute electrical service line to the outside
•Deck: Remove and replace existing pavement at specific locations and improve deck drainage

ACCESS and CLOSURES• SR-163 NB/SB Freeway: Nighttime closures to install scaffolding
• El Prado Street: Closures when deck pavement is replaced (5-day closures)
• Temporary closures to install temporary concrete rail and restriping that will provide on-going construction vehicles access

STAGING AREAS•At-grade trails (that pass under the bridge) will be impacted
•A portion of the trail west of SR 163 and north of the bridge will be dual use (people and construction vehicles) with flaggers on an as needed basis
•A portion of the archery range will have partial fencing and will be closed during construction
