The Charles Anderson Memorial Bridge is a steel deck truss bridge located in Pittsburgh, Pennsylvania, United States. The bridge carries the four-lane roadway of Boulevard of the Allies across a ravine known as Junction Hollow, connecting the neighborhoods of Central Oakland and South Oakland with Schenley Park.[6] The bridge also spans the Junction Hollow Trail and P&W Subdivision railroad tracks which run along the bottom of the valley.

The Anderson Bridge is a notable example of a Wichert truss, a rare bridge type with few surviving examples.[2] The Wichert truss is a type of modified continuous truss using a quadrilateral section over each support to make it statically determinate. The design was patented by Pittsburgh civil engineer Edward M. Wichert in 1930.[7] The Anderson Bridge is one of two Wichert truss bridges in Pittsburgh along with the Homestead Grays Bridge.

The bridge is a contributing property in the Schenley Park Historic District.[1][8] It was also assessed by the Pennsylvania Department of Transportation and Pennsylvania State Historic Preservation Office to be eligible for individual listing on the National Register of Historic Places under Criterion C, design/construction.[9]

The current steel bridge was completed in 1940 and is the second bridge at this location. It replaced the former Wilmot Street Bridge, which was built in 1907.

On February 1, 2023, the bridge was closed for emergency repairs, with officials announcing a three-year closure for rehabilitation shortly thereafter.[10]
