Donahue St / North Bridge Road / Bridgeway

The interchange at Donahue Street/North Bridge Boulevard/Bridgeway is in the city of Sausalito. The surrounding area includes a shopping center, office buildings, and a harbor. TAM’s study found several features that could be improved, such as short acceleration-and-merge lengths, short weaving distance, and shoulder widths that do not meet the current standard. These and other limitations are described in the Existing Conditions, Constraints, and Opportunities Report below.

Interchange Improvements

TAM proposes several improvements for the interchange to make it easier and safer to access Highway 101 and improve the flow of traffic. Proposed projects include restriping and widening the freeway. To gain an important understanding of the interchange area, the study examined the following:

  • Existing Infrastructure
  • Transit Routes and Intermodal Connectivity
  • Weekday AM & PM Peak Period Congestion
  • Crash Type and Severity
  • Environmental Constraints

 

Many of the study’s recommended changes will make the interchange easier to use for drivers, bicyclists, pedestrians, and people using public transit. The proposals will also increase safety at the interchanges and on surrounding streets and pathways, allowing for smoother travel to, from, and across Highway 101 and local roads.

The near-term improvement concept focuses on creating safer and easier access for everyone. Crosswalks will be restriped and a multi-use path between Terners Drive and Drake Avenue will be installed to reduce conflicts and improve traffic operations. Intersection signals will be upgraded at Terners Drive and the southbound off-ramp along Donahue Street.

The long-term concept expands upon the near-term improvements by extending the multi-use path to the east to connect an improved bicycle-friendly intersection. Donahue/N Bridge Blvd will be restriped between Bridgeway and Terners Drive to provide for a class II bike lane in the eastbound and westbound directions.

Public and Agency Input

Between March and April 2021, TAM surveyed residents of Marin to collect input about the 12 selected interchanges. More than 2,750 people responded to the survey. The survey was launched to gather the public’s thoughts and priorities on improvements to the interchange. TAM has incorporated the feedback we received to ensure the project reflects community values and preferences.

In the survey, 96 people commented on Donahue Street/N. Bridge Road/Bridgeway. Residents rated the level of importance for eight potential improvements on a 5-point scale ranging from not important to most important. The interchange report includes a summary of the survey results and comments received.

Most respondents said improving environmental sustainability and resiliency is the most important improvement to this interchange.

" Protected bike lanes and/or green surface treatment would go a long way for cyclist safety and predictability. The traffic lights seem to have long wait times, which causes many drivers to blow through red lights to avoid wait times. "
