Bridgeport Covered Bridge
Historic 1862 covered bridge at South Yuba River State Park. Longest single-span wooden covered bridge in the world, spanning 230 feet over the South Yuba River.
About Bridgeport Covered Bridge
The Bridgeport Covered Bridge stands as a magnificent testament to Gold Rush-era engineering and California's pioneering spirit. Spanning 230 feet across the South Yuba River, this remarkable structure holds the distinction of being the longest single-span wooden covered bridge in the entire world. Built in 1862 by master craftsman David John Wood during the height of the California Gold Rush and Nevada's silver boom, the bridge served as a vital link on the Virginia Turnpike toll road connecting Nevada's Comstock Lode with California's commercial centers.
Today, this National Historic Landmark draws over 150,000 visitors annually to South Yuba River State Park, where it serves as a stunning pedestrian gateway to the region's gold mining history and natural beauty. The bridge's distinctive covered design, combining a Howe Truss with an auxiliary Burr Arch, creates an iconic silhouette that has captivated photographers, historians, and travelers for generations.
History and Construction
In January 1862, California experienced what became known as the "1000-year storm," unleashing catastrophic flooding across the Sierra Nevada foothills. The deluge washed away the original bridge at Nye's Crossing, creating an urgent need for a replacement to maintain the lucrative commerce flowing between California and Nevada's silver mines. The Virginia Turnpike Company contracted David John Wood, an experienced bridge builder who operated a sawmill in Sierra County's Plum Valley, to construct a new, more resilient crossing.
Wood delivered an engineering marvel. By summer 1862, his crew had completed a 251-foot structure (including weather wings on each end) utilizing locally-sourced Douglas fir timbers hand-hewn with ax and adze. The bridge's innovative design combined a Howe Truss—wooden planks bolted together with wrought iron tension rods—with an auxiliary Burr Arch visible both inside and outside the structure. This dual-truss system, anchored by massive granite abutments, distributed weight efficiently and provided remarkable stability.
The bridge operated as part of a profitable toll road from 1862 to 1901. In its heyday, crossing fees ranged from 5 cents for a hog to $6 for an eight-horse team, generating between $4,000-$5,000 monthly—an extraordinary sum when $500 represented a good annual income. The route was so vital that stages often traveled at night due to the sheer volume of supply traffic during daylight hours, with the Virginia Turnpike carrying as much as 40% of all Gold Rush and Comstock commercial traffic between 1858 and 1864.
Architecture and Design
The Bridgeport Covered Bridge exemplifies 19th-century American bridge-building craftsmanship at its finest. The structure features a combination Howe Truss and Burr Arch design, a relatively rare configuration that provides exceptional strength and longevity. The Burr Arch consists of two 5-inch by 14-inch timbers bolted together with truss members wedged between them, creating a curved support system that transfers load to the granite abutments.
The bridge's exterior is clad in over 27,000 sugar-pine shingles that protect the interior timber framework from weather damage—the primary purpose of covering bridges in the relatively dry California climate. The clear span between footings measures 208 feet (the current overall length is 229 feet after weather wings were removed during restoration). At 16 feet wide, the bridge originally accommodated freight wagons, stagecoaches, and livestock, though it now serves exclusively as a pedestrian crossing.
The covering structure itself, with its distinctive gabled roof, creates the tunnel-like appearance that makes covered bridges so beloved. This design not only protected the structural timbers but also helped calm nervous horses by blocking their view of potentially frightening rushing water below.

Photography Tips
The bridge photographs beautifully from multiple vantage points. For classic shots, position yourself on the modern bridge downstream to capture the covered bridge's full profile against the river canyon backdrop. Early morning light (7-9 AM) provides soft, warm illumination on the bridge's weathered wood siding. Spring wildflowers add colorful foregrounds, while summer's lush greenery frames the structure perfectly. The interior tunnel view creates dramatic leading lines—shoot from either entrance looking through to the opposite side. During golden hour (late afternoon), the bridge glows against shadowed canyon walls. Winter occasionally brings light snow, creating rare and stunning compositions. For reflections, visit when water levels are lower (late summer/fall) and the South Yuba River runs clear and calm.
