Introduction

Led by the Transportation Authority, the Hillcrest Road Improvement Project will upgrade the roadway to modern standards and provide additional space for pedestrians and bicyclists. The project runs between the West Side Bridges Project to the west and the Southgate Road Interchange Improvement Project to the east. 

Improvements include: 

  • Removal of existing retaining walls and construction of new retaining walls (with drainage) set further into the hillside above Hillcrest Road, with design features to limit distractions for Bay Bridge drivers
  • Curb and gutter 
  • Street and pedestrian level lighting
  • Safety guardrails 
  • Drainage facilities, striping, signage and concrete barriers throughout the project’s length.
