The Eads Bridge is a combined road and railway bridge over the Mississippi River connecting the cities of St. Louis, Missouri and East St. Louis, Illinois. It is located on the St. Louis riverfront between Laclede's Landing, to the north, and the grounds of the Gateway Arch, to the south. The bridge is named for its designer and builder, James Buchanan Eads. Work on the bridge began in 1867, and it was completed in 1874. The Eads Bridge was the first bridge across the Mississippi south of the Missouri River. Earlier bridges were located north of the Missouri, where the Mississippi is smaller. None of the earlier bridges survive, which means that the Eads Bridge is also the oldest bridge on the river.
The Horseshoe Curve is a three-track railroad curve on Norfolk Southern Railway's Pittsburgh Line in Blair County, Pennsylvania. The curve is roughly 2,375 feet (700 m) long and 1,300 feet (400 m) in diameter. Completed in 1854 by the Pennsylvania Railroad as a way to reduce the westbound grade to the summit of the Allegheny Mountains, it replaced the time-consuming Allegheny Portage Railroad, which was the only other route across the mountains for large vehicles. The curve was later owned and used by three Pennsylvania Railroad successors: Penn Central, Conrail and Norfolk Southern.
The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania. It operated from 1834 to 1854 as the first transportation infrastructure through the gaps of the Allegheny that connected the midwest to the eastern seaboard across the barrier range of the Allegheny Front. Approximately 36 miles (58 km) long overall, both ends connected to the Pennsylvania Canal, and the system was primarily used as a portage railway, hauling river boats and barges over the divide between the Ohio and the Susquehanna Rivers. Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service.
The Wheeling Suspension Bridge is a suspension bridge spanning the main channel of the Ohio River at Wheeling, West Virginia. It was the largest suspension bridge in the world from 1849 until 1851. Charles Ellet Jr. designed it and supervised construction of what became the first bridge to span a major river west of the Appalachian mountains. It linked the eastern and western section of the National Road, and became especially strategically important during the American Civil War. Litigation in the United States Supreme Court concerning its obstruction of the new high steamboat smokestacks eventually cleared the way for other bridges, especially needed by expanding railroads. Because this bridge was designed during the horse-and-buggy era, 2-ton weight limits and vehicle separation requirements applied in later years until it was closed to automobile traffic in September 2019.
The Main Line of Public Works was a package of legislation passed by the Commonwealth of Pennsylvania in 1826 to establish a means of transporting freight between Philadelphia and Pittsburgh. It funded the construction of various long-proposed canal and road projects, mostly in southern Pennsylvania, that became a canal system and later added railroads. Built between 1826 and 1834, it established the Pennsylvania Canal System and the Allegheny Portage Railroad.
The Huey P. Long Bridge, located in Jefferson Parish, Louisiana, is a cantilevered steel through-truss bridge that carries a two-track railroad line over the Mississippi River at mile 106.1, with three lanes of US 90 on each side of the central tracks. It is several kilometers upriver from the city of New Orleans. The East Bank entrance is at Elmwood, Louisiana, and the West Bank at Bridge City.
The Pittsburgh, Cincinnati, Chicago and St. Louis Railroad, commonly called the Pan Handle Route, was a railroad that was part of the Pennsylvania Railroad system. Its common name came from its main line, which began at Pittsburgh, Pennsylvania, crossed the Northern Panhandle of West Virginia, and continued west to Bradford, Ohio, where it split into a northern line to Chicago and a southern one through Indianapolis, Indiana, to East St. Louis, Illinois.
The Smithfield Street Bridge is a lenticular truss bridge crossing the Monongahela River in Pittsburgh, Pennsylvania, USA.
The Coraopolis Bridge is a girder bridge over the back channel of the Ohio River connecting Grand Avenue on Neville Island to Ferree Street in Coraopolis, Pennsylvania. It opened in 1995 to replace a structure of historic significance. The original Pratt/Bowstring/Pennsylvania through truss spans, designed by Theodore Cooper, were formerly the (third) Sixth Street Bridge, spanning the Allegheny River, in downtown Pittsburgh, and were built in 1892 by the Union Bridge Company. They were floated downstream by the Foundation Company in 1927 rather than being demolished when the bridge was removed to enable construction of the present (fourth) Three Sisters (Pittsburgh) Sixth Street Self-anchored suspension bridge. However, by the late 1980s, the old bridge could no longer support traffic volumes and was replaced by a newer structure.
The Newark Bay Bridge of the Central Railroad of New Jersey (CNJ) was a railroad bridge in New Jersey that connected Elizabethport and Bayonne at the southern end of Newark Bay. Its third and final incarnation was a four-track vertical-lift design that opened in 1926, replacing a bascule bridge from 1904 which superseded the original swing bridge from 1887. The bridge served the main line of the CNJ, carrying daily interstate trains as well as commuter trains.
The Beaver Bridge is a rail bridge spanning the Ohio River between Monaca and Beaver, Pennsylvania. It consists of two spans: a southern cantilever through truss of 769 feet (234 m) with 320-foot (98 m) anchor arms; and a northern camelback through truss of 370 feet (110 m). The bridge currently carries two tracks of CSX Transportation.
The Panhandle Bridge carries two rail lines of the Port Authority "T" line across the Monongahela River in Pittsburgh, Pennsylvania. The name comes from Pennsylvania Railroad subsidiary Pittsburgh, Cincinnati, Chicago and St. Louis Railroad, also known as the Panhandle Route, which operated over the bridge.
The Ohio Connecting Railroad Bridge is a steel bridge which crosses the Ohio River at Brunot's Island at the west end of Pittsburgh, Pennsylvania, United States. It consists of two major through truss spans over the main and back channels of the river, of 508 feet (155 m) and 406 feet (124 m) respectively, with deck truss approaches.
Columbus Union Station was an intercity train station in Downtown Columbus, Ohio, near The Short North neighborhood. The station and its predecessors served railroad passengers in Columbus from 1851 until April 28, 1977.
The Pittsburgh Light Rail is a 26.2-mile (42.2 km) light rail system in Pittsburgh, Pennsylvania, and surrounding suburbs. It operates as a deep-level subway in Downtown Pittsburgh, but runs mostly at-grade in the suburbs south of the city. The system is largely linear in a north-south direction, with one terminus near Pittsburgh's central business district and two termini in the South Hills. The system is owned and operated by Pittsburgh Regional Transit. The T is one of the surviving first-generation streetcar systems in North America, with the oldest portions of the network dating back to 1903 and the Pittsburgh Railways. It is also one of only three light rail systems in the United States that continues to use the broad 5 ft 2+1⁄2 in Pennsylvania Trolley Gauge on its lines instead of the 4 ft 8+1⁄2 instandard gauge. In 2022, the system had a ridership of 2,429,500.
The Port Perry Branch is a rail line owned and operated by the Norfolk Southern Railway in the U.S. state of Pennsylvania. The line runs from the Pittsburgh Line in North Versailles Township southwest through the Port Perry Tunnel and across the Monongahela River on the PRR Port Perry Bridge to the Mon Line in Duquesne along a former Pennsylvania Railroad line.
The Pittsburgh to St. Louis Main Line was a rail line owned and operated by the Pennsylvania Railroad in the U.S. states of Pennsylvania, Ohio, Indiana, and Illinois. The line ran from Pittsburgh, Pennsylvania west via Steubenville, Ohio, Columbus, Ohio, Dayton, Ohio, Indianapolis, Indiana, Terre Haute, Indiana, and Vandalia, Illinois to East St. Louis, Illinois. In addition to its east end in downtown Pittsburgh, where it met the Main Line and Pittsburgh to Chicago Main Line, junctions included the Columbus to Chicago Main Line at Columbus, the C&X Branch at Xenia, the Columbus to Indianapolis Main Line via Bradford at New Paris, the Richmond Branch and Fort Wayne Branch at Richmond, the Louisville Branch and I&F Branch at Indianapolis, and the Peoria Branch at Farrington, Illinois.
The Pittsburgh and Castle Shannon Tunnel, also known as the Mount Washington Coal Tunnel, was a 3 ft 4 in narrow-gauge railway tunnel under Mt. Washington.
The Cork Run Tunnel, also known as the Berry Street Tunnel, is one of nine tunnels built in Pittsburgh, Pennsylvania on the original Pittsburgh and Steubenville Railroad. The tunnel was built beginning in 1851 as a single-track bore 2,100 feet (640 m) long, approached by deep open cuts, to connect central Pittsburgh with points to the west, on the south side of the Ohio River. A shaft was sunk from the overlying ridge to a point near the midpoint of the tunnel to speed construction and to provide ventilation. Work was suspended in 1856 due to financial troubles, and resumed in 1862. The tunnel was completed in 1865.
The St. Paul Pass Tunnel was a railway tunnel in the northwest United States at St. Paul Pass, on the Montana-Idaho border. The tunnel was on the main line of the Chicago, Milwaukee, St. Paul & Pacific Railroad, commonly known as "The Milwaukee Road."
