Mathilda Avenue Improvements at SR 237 and US 101

• Overview

• The Project proposes to improve Mathilda Avenue in the City of Sunnyvale from Almanor Avenue to Innovation Way, including on- and off-ramp improvements at the State Route 237/Mathilda Avenue and U.S. 101/Mathilda Avenue interchanges.  Specific improvements include modification to on- and off-ramps; removal, addition, and signalization of intersections; provision of new left-turn lanes, and modification for improved bicycle and pedestrian access.  The design features of the two Build Alternatives include reconfiguration of the US 101 and SR 237 interchanges with Mathilda Avenue. This includes ramp modifications; removal, addition and modification of signalized intersections; pavement rehabilitation; and enhanced bicycle and pedestrian facilities. In addition, the Build Alternatives would require modification to utilities, storm water facilities, street lighting, ramp metering, and signage.
  
  Objective
  
  To reduce congestion on Mathilda Avenue, improve mobility for all travel modes, and provide better access to local destinations throughout the City of Sunnyvale.

  

   The Build Alternatives would consist of the following roadway improvements:

  • Provide three continuous through lanes in each direction of Mathilda Avenue.
  • Remove northbound US 101 loop off-ramp and shift traffic to northbound US 101 diagonal off-ramp.
  • Realign and widen northbound ramps and signalize ramp intersection with Mathilda Avenue, and construct left-turn lane on southbound Mathilda Avenue to access northbound US 101 loop on-ramp.
  • Realign southbound US 101 off-ramp and loop on-ramp and signalize ramp intersection with Mathilda Avenue.
  • Modify Mathilda Avenue / Ross Drive signal intersection.
  • Close Moffett Park Drive between Bordeaux Drive and Mathilda Avenue and shift traffic to Bordeaux Drive and Innovation Way.
  • Remove westbound SR 237 ramp signal intersection. Realign westbound SR 237 off-ramp opposite Moffett Park Drive and modify signal intersection.
  • Build Alternative 1 would modify westbound SR 237 ramps to provide a diamond configuration.
  • Build Alternative 2 would modify Mathilda Avenue and SR 237 ramps to provide a diverging diamond configuration. Eastbound Moffett Park Drive between Innovation Way and Mathilda Way would be diverted to Innovation Way to access Mathilda Avenue.

  A Class III bicycle route is proposed on both sides of Mathilda Avenue between Almanor Avenue and Innovation Way. The bicycle lanes would connect with the existing signed on-street bicycle route north of Innovation Way. Bicycle access would also be maintained on Moffett Park Drive between Bordeaux Drive and Innovation Way.
  
  Continuous sidewalks would be provided along both sides of Mathilda Avenue except on the west side of Mathilda between Ross Drive and Moffett Park Drive due to width restrictions at the SR 237 Undercrossing. Crosswalks would be maintained at Ross Drive and Moffett Park Drive to allow pedestrians to cross Mathilda Avenue. New crosswalks at ramp intersections would be signalized.
