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.
The Stone Arch Bridge is a former railroad bridge crossing the Mississippi River at Saint Anthony Falls in downtown Minneapolis, Minnesota. It is the only arched bridge made of stone on the entire Mississippi River. It is the second oldest bridge on the river next to Eads Bridge. The bridge was built to connect the railway system to the new Union Depot, which at that time was planned to be built between Hennepin Avenue and Nicollet Avenue. The bridge was completed in 1883, costing $650,000 at the time. 117 Portland Avenue is the general address of the historic complex.
The Hennepin Avenue Bridge is the structure that carries Hennepin County State Aid Highway 52, Hennepin Avenue, across the Mississippi River in Minneapolis, Minnesota, at Nicollet Island. Officially, it is the Father Louis Hennepin Bridge, in honor of the 17th-century explorer Louis Hennepin, who was the first European to see the Saint Anthony Falls, a short distance downriver. Two of the three previous structures have been suspension bridges, while a third—which existed nearly a century—was composed of steel arch spans. The original crossing, which opened as a toll bridge on January 23, 1855, is believed to have been the first permanent span across the Mississippi at any point. Other bridges were completed in 1876, 1891, and most recently 1990. Today, the bridge's main span is 190 metres (620 ft) in length.
The Washington Avenue Bridge carries County Road 122 and the METRO Green Line light rail across the Mississippi River in Minneapolis and connects the East Bank and West Bank portions of the University of Minnesota campus. The bridge has two decks, with the lower deck designated for motor vehicle traffic and light rail trains and the upper deck used for pedestrians and bicycles. It is a utilitarian structure with simple architecture, but it has cultural significance because thousands of students, faculty, staff, and visitors walk across it every day.
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 Morrissy Bridge is a steel truss bridge crossing the Miramichi River at Miramichi, New Brunswick, Canada.
The South Tenth Street Bridge, most often called the Tenth Street Bridge, but officially dubbed the Philip Murray Bridge, is a suspension bridge that spans the Monongahela River in Downtown Pittsburgh, Pennsylvania.
The Uhlerstown–Frenchtown Bridge is a free bridge over the Delaware River, owned and operated by the Delaware River Joint Toll Bridge Commission. The bridge connects New Jersey Route 12 in Frenchtown of Hunterdon County, New Jersey with Pennsylvania Route 32 in Uhlerstown of Bucks County, Pennsylvania.
The Cape Girardeau Bridge was a continuous through truss bridge connecting Missouri's Route 34 with Illinois Route 146 across the Mississippi River between Cape Girardeau, Missouri, and East Cape Girardeau, Illinois. It was replaced in 2003 with the Bill Emerson Memorial Bridge.
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box.
The Anoka–Champlin Mississippi River Bridge, also known as the Ferry Street Bridge, is a 10-span open spandrel concrete deck arch bridge that spans the Mississippi River between Anoka and Champlin, Minnesota, United States. It was built in 1929 by the Minneapolis Bridge Company, replacing an 1884 bridge at the same site.
The Plymouth Avenue Bridge is a segmental bridge that spans the Mississippi River in Minneapolis. It was built in 1983 and was designed by Van Doren-Hazard-Stallings. The construction of this bridge was unique, for it was the first segmental concrete girder bridge built in Minnesota. This method of design uses a "form traveler" that shapes the concrete as it is built out from the piers. This avoided the use of falsework and avoided impeding river traffic. The concrete is also engineered to be salt-resistant by the use of post-tensioning. Tubes run through the concrete structure carrying strands of cable. With tension on the cables, the structure is designed to be under compression. This prevents cracks and hinders the intrusion of salt water. Since then, other bridges in Minnesota have used this construction method, including the I-35W Saint Anthony Falls Bridge in Minneapolis, the Wabasha Street Bridge in downtown St. Paul, and the Wakota Bridge in South St. Paul.
Broadway Avenue Bridge is a girder bridge that spans the Mississippi River in Minneapolis, Minnesota. Designed by Norman C. Davis and Shawn Pierson Bruns of Van Doren-Hazard-Stallings, it was built in 1987. The bridge has a rather streamlined shape, but its piers are more ornate. The piers have two flat columns that taper together, with a base that extends out to the full width of the bridge.
The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States. The bridge opened in 1967 and was Minnesota's third busiest, carrying 140,000 vehicles daily. It experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The NTSB cited a design flaw as the likely cause of the collapse, noting that an excessively thin gusset plate ripped along a line of rivets, and that additional weight on the bridge at the time contributed to the catastrophic failure.
The North Avenue Bridge can refer to one of three bridges that has carried North Avenue over the North Branch of the Chicago River on the north side of Chicago, Illinois. A center-pier swing bridge built in 1877 was replaced in 1907 by a bascule bridge, allowing river traffic more room for maneuvering in and out of the North Canal, just north of Goose Island.
Washington Crossing Bridge is a truss bridge spanning the Delaware River that connects Washington Crossing, Hopewell Township in Mercer County, New Jersey with Washington Crossing, Upper Makefield Township in Bucks County, Pennsylvania. It was built in 1904 by the Taylorsville Delaware Bridge Company. The bridge is currently owned and operated by the Delaware River Joint Toll Bridge Commission.
The Martin Olav Sabo Bridge is a bridge in the city of Minneapolis and the first cable-stayed suspension bridge in the U.S. state of Minnesota. Formerly the Midtown Greenway Pedestrian Bridge, it was renamed in honor of former Representative Martin Olav Sabo, a fourteen-term member of Congress from Minnesota.
