Knights Ferry

Gold Rush ferry town on the Stanislaus

Knights Ferry is an unincorporated community on the Stanislaus River in Stanislaus County, California, about twelve miles east of Oakdale on State Route 108/120. California Historical Landmark 347 and a National Register historic district (listed 23 April 1975) cover the living town and its river crossing. The U.S. Army Corps of Engineers manages Stanislaus River Parks recreation lands at and near the covered bridge; the bridge itself sits on Corps-managed land. Parts of the community are private residences and businesses.

In 1848–49, Capt. William Knight established a trading post and ferry on a crossing Frémont’s party had used in 1844, on the direct Stockton–Sonora road to the southern mines. After Knight’s death the Dent brothers ran the ferry; the place was also called Dentville. A dam, sawmill, and flour mill (Locke’s / Stanislaus Mills) followed in the mid-1850s. By 1856 the village held roughly 800 people. The town served as Stanislaus County seat from 1862 to 1872. An early uncovered timber bridge (1857) was destroyed in the great flood of 1861–62, which also wrecked mills and much of the town.

The covered bridge

The present Knight’s Ferry Bridge is a four-span wood-and-iron Howe truss covered bridge built 1863–64 by the Stanislaus Bridge & Ferry Company to replace the washed-out span. Total length is 330 feet (clear spans roughly 36, 92, 73, and 129 feet), making it the longest covered bridge west of the Mississippi River. HAER documentation (CA-314) describes mortared stone abutments and piers on natural rock, vertical board sheathing, and a gable roof now covered with standing-seam metal. The Howe truss combines wood chords and diagonals with vertical iron rods — a common mid-nineteenth-century type that HAER historians call a strong surviving example. The Corps closed the bridge to regular vehicle traffic in 1981; it has been used as a pedestrian crossing when open. New Melones Dam (Corps, 1979) reduced flood risk to the bridge and downstream towns. HAER and HABS recorded the structure; the bridge also carries National Historic Landmark recognition separate from the 1975 district listing.

California OHP’s landmark text notes local tradition linking U. S. Grant (brother-in-law of the Dents) to early bridge design; HAER treats that claim as legend rather than documented authorship of the 1863–64 structure.

Recreation area and visitor limits

Stanislaus River Parks (Sacramento District, USACE) maintains day-use areas, trails, and a visitor center in historic Knights Ferry with exhibits on salmon, Native American culture, the covered bridge, and the old flour mill. Project headquarters address is 17968 Covered Bridge Road, Oakdale; phone (209) 881-3517. Day-use and camping fees apply on Corps lands; confirm current rules, fire restrictions, and bridge status before you go — the Corps has closed the covered bridge for structural repairs for extended periods. The surrounding town remains residential; stay on public roads and Corps recreation areas, and do not enter private yards or closed buildings.

What these sources do not invent for you: temporary road closures, river flow for boating, or interior hours of every historic commercial shell. Use the Corps site and OHP landmark text as the baseline, then verify day-of conditions.
