National Register of Historic Places in Napa County
The Garnett Creek Bridge is an earth filled closed spandrel masonry arch of rough cut stone laid in irregular courses. The bridge has a single span measuring thirty-two feet. The roadbed has a length of fifty feet and a width slightly over twenty feet six inches. Both railings are constructed of cut stone. A rural setting of trees and fields surrounds the bridge.
The Garnett Creek Bridge is one of many masonry arch bridges built in Napa County in the late 19th and early 20th centuries. The combination of high quality building stone from nearby sources and the presence of skilled stonemasons can be seen in the many stone buildings and bridges that still exist throughout the county.

The bridge was damaged by the August 24, 2014 South Napa Earthquake and is closed indefinitely, pending full structural analysis of the damage and possible repair options; dealing with this bridge is years away.

Viewing the structure of Napa's stone bridges is a challenge. Access is often impeded by steep banks, exuberant vegetation and fences. We were fortunate to gain unobstructed views of several representative bridges: the Maxwell Creek Bridge, the Garnett Creek Bridge on Route 29 and the Pope Street Bridge.
