Fernbridge (bridge)
Fernbridge is a concrete arch bridge designed by American engineer John B. Leonard which opened in 1911 at the site of an earlier ferry crossing of the Eel River. Fernbridge is the last crossing before the Eel arrives at the Pacific Ocean, and anchors one end of California State Route 211 leading to Ferndale, California. When built, it was referred to as the "Queen of Bridges" and is still the longest functional poured concrete bridge in operation in the world. Construction After 17 years of petitioning by residents of Ferndale and the Eel River valley, Humboldt County Supervisors accepted bids for construction in 1910, and work started March 20 of that year. Reinforced concrete was used because studies after the 1906 San Francisco earthquake along of the San Andreas Fault from Ferndale south to San Jose, California showed that reinforced concrete withstood earthquakes. The nearly span cost to build, and consumed millions of board feet of local redwood timber for the fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eel River (California)
The Eel River (Wiyot: ''Wiya't''; Cahto: ''Taanchow''; Northern Pomo: ''ch'idiyu'') is a major river, about long, of northwestern California. The river and its tributaries form the third largest watershed entirely in California, draining a rugged area of in five counties. The river flows generally northward through the Coast Ranges west of the Sacramento Valley, emptying into the Pacific Ocean about downstream from Fortuna and just south of Humboldt Bay. The river provides groundwater recharge, recreation, and industrial, agricultural and municipal water supply.William M. Brown and John R. RitterSediment transport and Turbidity in the Eel River Basin, 1971, prepared in cooperation with the California Department of Water Resources, 67 pages The Eel River system is among the most dynamic in California because of the region's unstable geology and the influence of major Pacific storms. The discharge is highly variable; average flows in January and February are over 100 times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
