A bridge is an excellent idea at Britton & Wolfe as is a walkway along Britton. When Sunnyvale is able to build the East Channel trail from the Bay Trail to Ortega Park along this route, that would be a great opportunity to do both as part of this new trail network.
Please send this idea to the Sunnyvale Bicycle and Pedestrian Advisory Commission at firstname.lastname@example.org and ask that it be included in the Sunnyvale Bicycle, Pedestrian, and Safe Routes to School Master Plans. These are coming up for revision within the next year and this is done only once every 10-12 years. Thanks!
