Construction of the bridge to connect a popular trail in Sycamore Grove Park officially began with a groundbreaking ceremony on Monday, July 22nd. The bridge is the final step to permanently connect a 44-mile trail through five parks from Livermore to Fremont. A multi-year, multi-agency project spearheaded by non-profit Tri-Valley Conservancy, representatives from Alameda County, City of Livermore, East Bay Regional Park District, Livermore Area Recreation and Park District ceremoniously broke the ground in unison with golden shovels to symbolize the collaboration required to bring this project to fruition.

Alameda County Supervisor Scott Haggerty, a major supporter of Tri-Valley Conservancy’s Valley Trail Connections project, announced the bridge is officially named the “Edward R. Campbell Bridge” in honor of his predecessor who was instrumental in the creation of the South Livermore Valley Area Plan which helped to protect the natural and agricultural land in south Livermore, including the area of Sycamore Grove Park where the bridge is located. The Plan also launched the creation of Tri-Valley Conservancy to help preserve and steward the protected agricultural and natural lands in perpetuity. Tri-Valley Conservancy’s Executive Director Laura Mercier confirmed that naming the bridge for the late Supervisor Campbell points to the wonderful culmination of the vision that he helped to establish for the century-old wine region.

Once completed, the Edward R. Campbell Bridge will permanently connect the Arroyo del Valle trail in Sycamore Grove Park which links into the trail systems of Del Valle Regional Park, Ohlone Regional Wilderness, Sunol Regional Wilderness, and Mission Peak Regional Preserve. The route will become part of the Juan Bautista de Anza National Historic Trail--one of just thirty National Historic Trails in the country. The bridge will also open permanent year-round access for park visitors with horses, bicycles, strollers, and wheelchairs.

It has taken Tri-Valley Conservancy several years to coordinate including the 2014 purchase and preservation of the 74-acres of land where the trail will connect. “Thanks to our partners and donors, we’re finally at the last step of the Valley Trail Connections project which will link 25,000 acres of open space, help improve creek habitat, and allow year-round access for park visitors to these amazing preserved lands,” Mercier explained.

Tri-Valley Conservancy credits key partners Alameda County Supervisor Scott Haggerty, Alameda County Transportation Commission, Bay Area Barns and Trails, California State Coastal Conservancy, Chevron, City of Livermore, Dean Witter Foundation, East Bay Regional Park District, Friends of Open Space and Vineyards, Livermore Area Recreation & Park District, Sierra Club, Teichert, The Joseph & Vera Long Foundation, Altamont Open Space, and Zone 7 Water Agency for bringing this project to fruition.

The groundbreaking also marked the temporary closure of the bridge site during construction.
