Pedestrian-Bicycle
East Campbell Avenue Portals ProjectTo maintain the safety of pedestrians & bicyclists and create an aesthetically pleasing gateway portal, the City of Campbell constructed two portals by modifying the existing bridge that carries Highway 17 over Campbell Avenue. The portals connect the Pruneyard Shopping Center with Downtown Campbell. Biggs Cardosa was the prime consultant providing project management and leading a design team to provide the City a complete PS&E package that included aspects such as structural elements, civil/roadway elements, aesthetics, safety, right-of-way, electrical, constructability, local business impacts, community involvement, and others. All work was coordinated with Caltrans to obtain permits for improvements within Caltrans ROW and for modifying the existing Campbell Avenue Undercrossing. This project was awarded the 2018 ACEC California Honor Award in the Structural Systems category.

South Bayfront Pedestrian Bicycle BridgeThe South Bayfront Pedestrian Bicycle Bridge is a tied arch bridge over the Union Pacific Railroad yard and two mainline railroad tracks in the City of Emeryville. The $21M bridge project includes the 230-foot-long signature Main Bridge and other structures which enhance connectivity on the east and west sides of the railroad corridor. The city has long been bisected by the UPPR tracks, limiting east to west connectivity within the city. The new ADA-compliant bridge provides pedestrians and bicyclists a safe connection, linking the east and west sides of the city over the railroad tracks. The signature feature of the project - the main arch span - consists of an S-curved single span across the railroad tracks, supported at its ends by concrete bents. The unique combination of S-curved deck and asymmetrical single tied-arch creates a striking image while resolving complex site conditions. The arch span is supported by a single straight bowstring truss/arch that extends diagonally across the deck; the top chord/arch rib is a pair of steel tubes, the bottom chord/tension tie is within the deck framing, and the cable diagonals/suspenders support the deck edges.

Central Marin Ferry Connection Multi-Use PathwayThe Central Marin Ferry Connection (CMFC) Multi-Use Pathway (MUP) project “closes the gap” by connecting the Cal Park Tunnel Pathway and a future SMART train station from the north to the Larkspur Ferry Terminal and a network of MUP’s to the south of East Sir Francis Drake (ESFD) Boulevard in the City of Larkspur. The Transportation Authority of Marin (TAM) retained Biggs Cardosa to lead a well-rounded team of consultants in order to provide preliminary and final engineering services that include: evaluation of 15 alternative “landmark” bridge types; various alignment alternatives; public forum presentations; mitigating numerous issues involving environmental limitations within a Bay salt marsh area; physical constraints within SMART right-of-way; obtaining environmental permits from several agencies; design of structures that include a pedestrian bridge, elevated ramp structure, MSE walls, wood boardwalk, a new MUP, and various sidewalk improvements within both City right-of-way and privately owned parcels. This project was awarded the 2017 ACEC California Honor Award in the Structural Systems category.

Caltrain Santa Clara Station Pedestrian UndercrossingThe Santa Clara Valley Transportation Authority proposed and constructed an 83-foot long undercrossing to serve as a connection to a new Caltrain station platform, extending the undercrossing that was currently being constructed by Caltrans. Biggs Cardosa was selected to provide project management and structural design for a 35% level PS&E which included a preliminary engineering report, 35% plans, a preliminary cost estimate, a preliminary construction schedule, and support services in coordination with UPRR. Under a separate contract, Biggs Cardosa was selected to lead a multi-disciplined team to provide a complete PS&E package and technical support for the successful construction of the PUC extension. This project was received the 2018 ACEC GOLDEN STATE AWARD and 2018 APWA Project of the Year Award.

Clarke Avenue Pedestrian Overcrossing at US-101Biggs Cardosa provided structural design consultation services throughout the feasibility study phase of the project, and provided project management and structural design services for the bridge PS&E portion. This $13 million bicycle and pedestrian bridge gives residents of East Palo Alto's west side, which has virtually no amenities, access to its shopping center, schools, churches, city government, parks and open spaces. Residents on the east side, many of whom work in Palo Alto, will soon be able to bike to work and have access to libraries, parks and other local and regional attractions, The two sides of East Palo Alto separated by bustling U.S. Highway 101 will soon link again for the first time in more than 60 years.
