full_context: Document 1: South Tenth Street Bridge: South Tenth Street Bridge, most often called the Tenth Street Bridge, but officially dubbed the Philip Murray Bridge, is a suspension bridge spanning the Monongahela River in Downtown Pittsburgh, Pennsylvania. The bridge was renamed on Labor Day 2007 for Philip Murray, the first president of the United Steelworkers of America.
Document 2: Thirteen Most Wanted Men: Thirteen Most Wanted Men was a large mural created by Andy Warhol for the New York State Pavilion at the 1964 World's Fair at Flushing Meadows, New York. The mural was painted over with silver paint before the fair opened, probably due to official objections, but other reasons have been suggested.
Document 3: Capital punishment in the United States: Electrocution was the preferred method of execution during the 20th century. Electric chairs have commonly been nicknamed Old Sparky; however, Alabama's electric chair became known as the "Yellow Mama" due to its unique color. Some, particularly in Florida, were noted for malfunctions, which caused discussion of their cruelty and resulted in a shift to lethal injection as the preferred method of execution. Although lethal injection dominates as a method of execution, some states allow prisoners on death row to choose the method used to execute them.
Document 4: 30th Street Bridge: The 30th Street Bridge, is a girder bridge that carries vehicular traffic across the Allegheny River between the Pittsburgh neighborhoods of Troy Hill and Herrs Island (known by the moniker of Washington's Landing). This is the fourth bridge that has stood on this site. A wooden 19th Century bridge was washed away during an 1882 flood. This was replaced by an arch bridge that spanned the entire width of the Allegheny River; after a 1921 fire destroyed the span across the main channel, the 31st Street Bridge was constructed as a replacement, and this bridge was again relegated to taking traffic to Herrs Island. A 1939 truss bridge then stood on this site, and it was replaced by the current structure as part of the redevelopment of the island to feature condominiums and a business park instead of warehouses and stockyards.
Document 5: Texas Prison Museum: The non-profit museum features the history of the prison system in Texas (Huntsville is the home of the Texas Department of Criminal Justice and several prisons including the Ellis Unit which previously housed death row, and Huntsville Unit which houses the execution chamber).

Document 6: 31st Street Bridge: The William Raymond Prom Memorial Bridge, commonly known as the 31st Street Bridge, is an arch bridge that carries vehicular traffic across the Allegheny River between the Pittsburgh neighborhoods of Troy Hill and the Strip District.

Document 7: Brady Street Bridge: The Brady Street Bridge, also known as the South 22nd Street Bridge, was a steel bowstring arch bridge in Pittsburgh, Pennsylvania, which crossed over the Monongahela River at South 22nd Street. It was replaced by the Birmingham Bridge in 1976, and was demolished on May 29, 1978. The bridge's main span was a tied arch with a suspended road deck, with two through-truss side spans, carrying two traffic lanes between Brady Street on the Pittsburgh side and South 22nd Street on the south side. Approach viaducts were built at either end. The bridge was built by the Schultz Bridge and Iron Company.

Document 11: Big Electric Chair: Created in 1967, the Stockholm Big Electric Chair is part of a series of works by Andy Warhol depicting an electric chair. Death by electrocution was a controversial subject in New York City, where the artist lived and worked, especially after the last two executions at Sing Sing Correctional Facility in 1963. Warhol obtained a photograph of the empty execution chamber, which became the basis for this series.

Document 14: Electric chair: A number of states still allow the condemned person to choose between electrocution and lethal injection. In all, twelve inmates nationwide - seven in Virginia, three in South Carolina, and one each in Arkansas and Tennessee - have opted for electrocution over lethal injection. The last use of the chair was on January 16, 2013, when Robert Gleason, Jr., decided to go to the electric chair in Virginia.
