Phyllis J. Tilley Memorial Bridge
The Phyllis J. Tilley Memorial Bridge is a pedestrian bridge in Fort Worth, Texas, Fort Worth, Texas. Description The Phyllis J. Tilley Memorial Bridge crosses over the Trinity River (Texas), Trinity River connecting Trinity Park to a new trail that terminates in downtown Fort Worth. This 368' (112m) long steel stressed ribbon/arch combination bridge is the first of its kind in North America. A steel arch with a span of 163' (49.5m) supports steel stress ribbons and precast concrete planks over the river complementing the adjacent historic Lancaster Avenue vehicular bridge. The arch spans the entire river and the steel stress ribbons rest upon the arch. The minimal sag profile of the stressed ribbons creates major tension loads which are balanced against the thrust loading in the opposite direction caused by the steel arch. The balancing of these opposing loads minimizes the required size of the foundations. Pre-fabricated concrete planks have been anchored directly to the steel ...

Trinity River (Texas)
The Trinity River is a river, the longest with a watershed entirely within the U.S. state of Texas. It rises in extreme northern Texas, a few miles south of the Red River. The headwaters are separated by the high bluffs on the southern side of the Red River. Indigenous peoples call the northern sections ''Arkikosa'' and the parts closer to the coast ''Daycoa''. French explorer Robert Cavelier de La Salle, in 1687, named it ''Riviere des canoës'' ("River of Canoes"). In 1690 Spanish explorer Alonso de León named the river ''"La Santísima Trinidad"'' ("the Most Holy Trinity"), in the Spanish Catholic practice of memorializing places by religious references. Course The Trinity River has four branches: the West Fork, the Clear Fork, the Elm Fork, and the East Fork. The West Fork Trinity River has its headwaters in Archer County. From there it flows southeast, through the man-made reservoirs Lake Bridgeport and Eagle Mountain Lake, and eastward through Lake Worth and the ...

Stressed Ribbon Bridge
A stressed ribbon bridge (also stress-ribbon bridge or catenary bridge) is a tension structure (similar in many ways to a simple suspension bridge). The suspension cables are embedded in the deck, which follows a catenary arc between supports. Unlike the simple span, the ribbon is stressed in traction, which adds to the stiffness of the structure (simple suspension spans tend to sway and bounce). The supports in turn sustain upward-thrusting arcs that allow the grade to be changed between spans (where multiple spans are used). Such bridges are typically made from concrete reinforced by steel tensioning cables. Where such bridges carry vehicle traffic, a certain degree of stiffness is required to prevent excessive flexure of the structure, obtained by stressing the concrete in compression. Examples * Lake Hodges Pedestrian Bridge, California - the longest stressed ribbon bridge in the world, measuring . * Leonel Viera Bridge, Uruguay - the first stressed ribbon bridge ever bu ...

Pedestrian Bridges In The United States
A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement, but this was not the case historically. The meaning of pedestrian is displayed with the morphemes ''ped-'' ('foot') and ''-ian'' ('characteristic of'). This word is derived from the Latin term ''pedester'' ('going on foot') and was first used (in English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks. The word pedestrian may have been used in middle French in the Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne, à présent nommé Engleterre. In California the definition of a pedestrian has been broadened to include anyone on any human powered vehicle that is not a bicycle, as well as people operating self-propelled wheelchairs by reason of ph ...
