Construction Underway to Transform Mathilda Avenue Interchanges

The much-anticipated improvements for the US-101/Mathilda Avenue and SR-237/Mathilda Avenue interchanges are officially starting. A contract was recently awarded to Ghilotti Construction Company. Construction activities will begin in mid-February through mid-2020. VTA, City of Sunnyvale, and Caltrans are partnering on this project supported in part by 2016 Measure B funds.

Project Benefits

This project is designed to reduce congestion and improve traffic on Mathilda Avenue for all modes of travel including pedestrians, bicycles, and transit. It will provide better access to local destinations and major employment centers throughout the City of Sunnyvale by:

  • Implementing “Complete Street” design at the US-101 Mathilda interchange
  • Widening Mathilda Avenue to provide three lanes in each direction
  • Including dedicated bike lanes and continuous sidewalks for pedestrians along Mathilda Avenue
  • Providing a new multi-purpose trail along Moffett Park Drive that connects to the existing pedestrian overcrossing at Borregas Avenue and extends to Innovation Way, adjacent to SR-237 

What to Expect

While a project’s overall benefits far outlive short-term construction impacts, it’s important to note the impacts for those who live, work, operate a business near, or drive through the project area. Activities will likely generate noise and traffic inconveniences, including but not limited to:

  • Saw cutting and jackhammering used for concrete and pavement removal
  • Installing K-rail (barriers) for worker, pedestrian, and traffic safety
  • Heavy construction equipment and back up alarms
  • Dust
  • Lane closures and detours
  • Temporary striping and lane shifts
  • Sidewalk closures and detours
  • Tree removal, tree planting and landscaping
  • Temporary bus stop closures

This $42 million investment is made possible through a combination of funds from the City of Sunnyvale, 2016 Measure B, and SB1 Local Partnership Program.
