22 Bridges. One Path Back to the Redwoods.
The map below shows the locations of the 22 bridges and crossings that need to be built to open Timms Creek Loop.
Stretching across nearly five miles of trail, these crossings once helped visitors safely move through Big Basin's redwood forests, across creeks, and deeper into the heart of the park. Today, each bridge represents an opportunity to restore access and reconnect people to this beloved landscape.
Together, these crossings form the pathway back.
Each numbered bridge on the map corresponds to a fundraising opportunity below. Bridge fundraising goals range from $2,500 to $25,000.
Bridge Champion Opportunities
From small creek crossings to larger structures, every bridge is a vital link in restoring nearly five miles of trail through Big Basin's redwood forest.

Built to Last
The bridges along Timms Creek Loop are designed to last. Their structural supports are made of fiberglass and cement, while the walkways and railings are made of redwood. Together, these materials are designed to resist rot and withstand low-intensity fires.
