Highland Park Bridge
The Highland Park Bridge is a truss bridge that carries vehicular traffic across the Allegheny River between the Pittsburgh neighborhood of Highland Park and the suburb of Aspinwall. It replaced a much narrower 1902 streetcar bridge that was ill-equipped to handle heavy commuter traffic, as part of the process of suburbanization in the hills northeast of the city. History The bridge was designed by Sidney A. Shubin, chief bridge design engineer of Allegheny County, who also designed the South Tenth Street Bridge and Homestead High Level Bridge. Construction of the bridge began on November 6, 1937 and was completed in June 1939. The bridge cost $2.5 million to construct and was opened on June 22, 1939. Two workers were killed during the construction on October 14, 1938 when a 68-ton crane fell from the bridge.

Allegheny River
The Allegheny River ( ) is a long headwater stream of the Ohio River in western Pennsylvania and New York (state), New York. The Allegheny River runs from its headwaters just below the middle of Pennsylvania's northern border northwesterly into New York then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio on the "Point" of Point State Park in Downtown Pittsburgh, Pennsylvania. The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers. The shallow river has been made navigable upstream from Pittsburgh to East Brady, Pennsylvania, East Brady by a series of locks and dams constructed in the early 20th century. A 24-mile long portion of the upper river in Warren County, Pennsylvania, Warren and McKean County, Pennsylvania, McKean counties of Pennsy ...

Bridges Over The Allegheny River
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.

Senator Robert D
A senate is a deliberative assembly, often the upper house or chamber of a bicameral legislature. The name comes from the ancient Roman Senate (Latin: ''Senatus''), so-called as an assembly of the senior (Latin: ''senex'' meaning "the elder" or "old man") and therefore considered wiser and more experienced members of the society or ruling class. However the Roman Senate was not the ancestor or predecessor of modern parliamentarism in any sense, because the Roman senate was not a legislative body. Many countries have an assembly named a ''senate'', composed of ''senators'' who may be elected, appointed, have inherited the title, or gained membership by other methods, depending on the country. Modern senates typically serve to provide a chamber of "sober second thought" to consider legislation passed by a lower house, whose members are usually elected. Most senates have asymmetrical duties and powers compared with their respective lower house meaning they have special dut ...

Brilliant Branch Railroad Bridge
The Brilliant Branch Railroad Bridge is a truss bridge that carries Allegheny Valley Railroad's Brilliant Branch across the Allegheny River between the Pittsburgh neighborhood of Highland Park and the borough of Aspinwall, Pennsylvania. History The Brilliant Branch, along with the Port Perry Branch along the Monongahela River was built by the Pennsylvania Railroad as part of a bypass of the narrow tracks around Downtown Pittsburgh. After the collapse of the Penn Central Transportation Company (the PRR's successor company) in 1976, the Brilliant Branch was abandoned. In 1995, they were purchased by the fledgling Allegheny Valley Railroad and in 2003, the Brilliant Branch Bridge was reopened. It generally served one train per day in each direction.

Blue Belt (Pittsburgh)
The Allegheny County Belt System color codes miscellaneous county roads to form a unique system of routes in Allegheny County, Pennsylvania, and around the city of Pittsburgh. Unlike many major American cities that utilize number-coded limited-access roads to form belt systems, the belts in the Allegheny County Belt System are not intended to be used as high-speed routes. Rather, the belt system is to be used as a navigational aid for motorists in unfamiliar portions of the county. Roads that make up the Belt System retain their previous names. The five original routes are, from outermost to innermost, the Red, Orange, Yellow, Green, and Blue Belts. The Purple Belt was not part of the original system and was added later. History The Allegheny County Belt System was developed in the late 1940s by Joseph White, an engineer with the Allegheny County Department of Public Works, as a wayfarer system using a network of federal, state, and municipal roads to offer residents alternative ...

Homestead High Level Bridge
The Homestead Grays Bridge, also known as the (Homestead) High Level Bridge, was built in 1936 and spans the Monongahela River between Homestead Borough and the southernmost tip of Pittsburgh's Squirrel Hill neighborhood. It is notable as the first bridge to incorporate the Wichert Truss, which uses a quadrilateral shape over each support, into its design. This made the truss statically determinate, so that forces in the structural members could be calculated. There are very few surviving Wichert Truss bridges, including one other example in Pittsburgh, the Charles Anderson Memorial Bridge. History The bridge was dedicated on Saturday November 20, 1937, having cost the county of Allegheny $2.75 million to build and originally carried four highway lanes and two streetcar tracks of Pittsburgh Railways Company. It replaced the 1897 Brown's Bridge (Homestead and Highland Bridge) which was upstream and had linked Brown's Hill Rd on the north bank and Second Avenue between Ann Street ...

Highland Park Bridge (1902)
The 1902 Highland Park Bridge was a cantilever through truss that carried two streetcar tracks across the Allegheny River and Sixmile Island between the Pittsburgh neighborhood of Highland Park and Sharpsburg, Pennsylvania. It was replaced by the Highland Park Bridge in 1938. Location The bridge was erected in two sections, with the cantilever on the Pittsburgh side of Sixmile Island and a truss bridge on the Sharpsburg side. It was situated downstream from the 1938 Highland Park bridge, at the then downstream from the end of the island. However, contemporary maps and pictures imply that the island has moved almost its entire length downstream, making the bridge location the current (2010) upstream end of the island.
