The Town of Tiburon in partnership with Marin County and CalTrans installed "bike boxes" at the Blackfield Drive and Greenwood Cove Drive approaches to Tiburon Boulevard (State Route 131). The aim of these measures is to provide safer cycling and traffic conditions.
What is a Bike Box?
The bike box is an intersection safety design to prevent bicycle/car collisions. It is a painted green space on the road with a white bicycle symbol inside. It includes a green bicycle lane approaching the box. The box creates space between motor vehicles and the crosswalk that allows bicyclists to position themselves ahead of motor vehicle traffic at an intersection.
Why were Bike Boxes Installed?
The bike boxes are funded through TAM's Safe Pathways to School Program to improve children cyclist safety on the way to and from school. The main goal of the project is to improve safety by:
- Increasing awareness and visibility of cyclists, especially school age children.
- Helping cyclists make safer intersection crossings.
- Encouraging cyclists to make more predicable approaches to and through an intersection.
- Providing space at the front of an intersection to help cyclists avoid breathing vehicle fumes.
