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 f ... [...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 tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Bridges On The National Register Of Historic Places In California
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which ...

Bridges Completed In 1911
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Concrete Bridges In California
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2022 Ferndale Earthquake
On December 20, 2022, a magnitude 6.4 earthquake struck Ferndale, California in Humboldt County, United States at 10:34:25 UTC, or 2:34 a.m. PST. Tectonic setting Much of Northern California lies close to the boundaries between three tectonic plates, the Pacific Plate, the Gorda Plate and the North American Plate, which meet at the Mendocino Triple Junction. The Mendocino Fracture Zone marks the transform boundary between the Gorda and Pacific plates. This tectonic boundary has been the cause of many earthquakes in the region, including the megathrust 1700 Cascadia earthquake, and the 1992 Cape Mendocino earthquakes, the latter of which measured 7.2. Earthquake The earthquake measured 6.4 on the moment magnitude scale, and had a maximum Mercalli intensity of VIII (''Severe''). It came exactly a year after a 6.2 magnitude earthquake struck onshore in the Cape Mendocino area on December 20, 2021, causing only minor damage. It was the result of strike-slip faulti ...
