San Bruno Grade Separation ProjectSan Bruno, California
A high number of fatalities occurring at train crossings in San Bruno, Calif., warranted the need for the San Bruno Grade Separation Project, which provides safer crossing options for both vehicles and pedestrians. The project provides an elevated commuter rail trackway, a new railway station/intermodal facility and new pedestrian undercrossings at three corridor locations, as well as a variety of context-related landscape, urban design, and public safety features.
HNTB served in a wide range of roles on the project, providing these services:
• Feasibility studies
• Conceptual design development
• Preparation of detailed engineering designs and drawings
• Utility coordination
• Development of utility relocation plans
• Preparation of staging plans and construction specifications
• Constructability reviews
• Procurement specifications
• Preparation of construction cost estimates
• Development of construction schedules
• Design support during construction
• Preliminary design for future electrification
• Realignment of mainline track
HNTB also provided design services for bridge structures, station structures, mechanically stabilized embankment structures, architecture, track, roadway, pump stations, elevators, utilities, closed circuit TV, communication systems, overhead catenary systems, grounding, electrical, landscape, flood risk management, drainage and railroad signals throughout the project.
Now in use, the grade separation project has eliminated vehicle-train collisions and greatly reduced pedestrian fatalities.
