Minato Bridge

The Minato Bridge is a double-deck cantilever truss bridge in Osaka, Japan; upper deck is for Hanshin Expressway Route 16 Osakako Line, and lower deck is Route 5 Bayshore Line. It opened in 1974. It is the third-longest cantilever truss span in the world, behind the Quebec Bridge and the Forth Bridge. [2]

Contents

Designs including arch and suspension elements were eliminated from consideration due to poor subsoil conditions of alternating layers of clay and gravel. Instead, the designers selected a cantilever structure using high-strength steel, to reduce mass. [2]

The Great Hanshin Earthquake occurred on January 17, 1995, at 05:46:53 JST in the southern part of Hyōgo Prefecture, Japan, including the region known as Hanshin. It measured 6.9 on the moment magnitude scale and had a maximum intensity of 7 on the JMA Seismic Intensity Scale. The tremors lasted for approximately 20 seconds. The focus of the earthquake was located 17 km beneath its epicenter, on the northern end of Awaji Island, 20 km away from the center of the city of Kobe.

The Steel Bridge is a through truss, double-deck vertical-lift bridge across the Willamette River in Portland, Oregon, United States, opened in 1912. Its lower deck carries railroad and bicycle/pedestrian traffic, while the upper deck carries road traffic, and light rail (MAX), making the bridge one of the most multimodal in the world. It is the only double-deck bridge with independent lifts in the world and the second oldest vertical-lift bridge in North America, after the nearby Hawthorne Bridge. The bridge links the Rose Quarter and Lloyd District in the east to Old Town Chinatown neighborhood in the west.

<span class="mw-page-title-main">Cantilever bridge</span> Bridge built using cantilevers

A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.

<span class="mw-page-title-main">Truss bridge</span> Bridge whose load-bearing superstructure is composed of a truss

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently.

The Ross Island Bridge is a cantilever truss bridge that spans the Willamette River in Portland, Oregon. It carries U.S. Route 26 across the river between southwest and southeast Portland. The bridge opened in 1926 and was designed by Gustav Lindenthal and honors Oregon pioneer Sherry Ross. It is named for its proximity to Ross Island. Although it looks like a deck arch bridge, it is a cantilever deck truss bridge, a rare type in Oregon.

The Isaiah David Hart Bridge is a truss bridge that spans the St. Johns River in Jacksonville, Florida. It carries U.S. Route 1 Alternate and State Road 228 (SR 228). It is named after Isaiah Hart, the founder of Jacksonville and is often referred to as the Hart Bridge. It was designed by Sverdrup & Parcel. The Hart Bridge is one of the longest truss bridges in the world, and has the world's third longest main span of any truss bridge.

The Glenwood Bridge is a cantilever bridge in Pittsburgh, Pennsylvania, which carries Pennsylvania Route 885 over the Monongahela River. It started construction on June 3, 1958.

<span class="mw-page-title-main">Tied-arch bridge</span> Type of bridge

A tied-arch bridge is an arch bridge in which the outward-directed horizontal forces of the arch(es) are borne as tension by a chord tying the arch ends rather than by the ground or the bridge foundations. This strengthened chord may be the deck structure itself or consist of separate, independent tie-rods.

<span class="mw-page-title-main">Miami Bridge</span> Bridge in Miami, Missouri

The Miami Bridge, also known as the McDaniel Memorial Bridge, is a new concrete girder bridge that was built to replace a cantilever through truss bridge over the Missouri River at Miami, Missouri between Saline County, Missouri and Carroll County, Missouri. The Miami Bridge carries Route 41. The Miami Bridge was built in 1939, and its deck was replaced in 1983 as part of a rehabilitation project. The old bridge's main cantilever span was 474.7 feet, while the two anchor spans were each 415 feet in length, resulting in a total cantilever truss length of 1304.7 feet. There were 11 approach spans, including four Warren deck truss spans, three on the northern approach and one on the southern approach. All remaining approach spans were steel stringer (multi-beam/girder) spans. Total bridge length including approach spans is 2,071.9 feet. The bridge's deck width is 23.0 feet and it has vertical clearance of 16.5 feet.
