The centerpiece of an improved trail through the Tennessee Valley in Southern Marin was slipped into place Friday morning.

"It all went very smoothly, there were no problems," said Todd Coleman, engineering assistant with the Marin County Department of Public Works.

A concrete floor still needs to be poured on the 100-foot span, which is scheduled to open next Friday. The bridge was lowered into place by a hydraulic crane across Coyote Creek in Mill Valley.

The structure is part of a $2.6 million federally funded county trail improvement project designed to connect the Tennessee Valley Trail along Coyote Creek with the Mill Valley-Sausalito multi-use trail.

The new bridge will allow people access across the creek, much as an existing span does now near the Dipsea Cafe. However, the old bridge is not in compliance with Americans with Disability Act rules because of its steep grade.

The old bridge will remain for those who want to use it, officials said.

"Everyone will be able to use the new bridge — pedestrians, bicyclists, people in wheelchairs and equestrians," said Jeri Stewart, a county spokeswoman.

The larger project — set to be finished by November — also includes signals at a crossing at Shoreline Highway, making it easier for people from the Tam Valley to gain access to the Mill Valley-Sausalito north-south trail.

A portion of the improved path includes a raised boardwalk so the path is not submerged during high tides. Another part of the trail — between the Tamalpais Community Services District cabin and Marin Avenue — will be a cantilevered boardwalk.

 

The Mill Valley-Sausalito path, which has been designated as part of the Bay Trail, provides access for bicycle commuters, access to recreational areas and connections to regional transit and local schools.
