Charles Anderson Memorial Bridge

After Schenley Park was established in 1889, residents of South Oakland wanted a bridge in their neighborhood so they could access the park without traveling to Forbes Avenue. When the original park entrance bridge was replaced by the Schenley Bridge in 1897, it was hoped that the old bridge would be moved to the end of Wilmot Street to provide this South Oakland entrance. However, the old bridge was scrapped instead.^[16]

Work finally began on the Wilmot Street Bridge in 1905 and was completed in 1907. The work was marked by labor trouble. When the unionized ironworkers went on strike for higher wages, the American Bridge Company replaced them with non-union strikebreakers and hired Pinkerton detectives to guard the work site.^[17] This resulted in several violent confrontations and at least two attempts were made to blow up the bridge with dynamite.^[18][19]

The two-lane Wilmot Bridge was sufficient at the time it was built. However, when Wilmot Street was widened to become part of Boulevard of the Allies in 1930,^[20] the merge from three lanes down to one lane at the bridge became one of Pittsburgh's most notorious traffic bottlenecks.^[21] To alleviate this problem, the city began work on a replacement bridge in 1938.^[22] The project was partially funded by a grant from the Public Works Administration.^[23] The new bridge used the patented Wichert truss design, which the city paid $12,500 to license from the Wichert Continuous Bridge Corporation,^[24] and was built by the Fort Pitt Bridge Company. It required 1,920 tons of structural steel, 120 tons of reinforcing steel, and 1,790 feet of iron railing.^[25]

In 1939,^[26] city officials decided to name the new bridge after the late Charles Anderson (1877–1939), a 20-year member of the Pittsburgh City Council who was a strong supporter of organized labor and whom the Pittsburgh Sun-Telegraph described as a "rugged, two-fisted politician".^[27] The bridge opened to traffic in April 1940, after which crews began dismantling the Wilmot Street Bridge immediately to the north.^[28] The Charles Anderson Memorial Bridge was formally dedicated two months later on June 22.^[29] In addition to the new bridge, the project also included a partial cloverleaf interchange to speed up traffic through Schenley Park.^[4]

In 1982, the two outside lanes of the bridge were closed due to structural deterioration.^[30] Eventually, a $2.3 million rehabilitation project was undertaken in 1987–88, during which the concrete deck was replaced, and the steel superstructure was repaired and painted. Following this project, the closed lanes were reopened.^[31]

As of 2022, the bridge deck, superstructure, and substructure condition were all rated as poor, and the posted weight limit of 32 tons meant the bridge was unable to accommodate the city's largest emergency vehicles. A city feasibility study concluded that the best course of action was to rehabilitate, rather than replace, the historic bridge, with work planned to start in 2025.^[8]

On February 1, 2023, city officials announced that the bridge would immediately close to vehicular traffic after a new structural analysis determined it was unsafe. Mayor Ed Gainey said the closure was necessary to prevent "another Fern Hollow",^[32] referring to the collapse of the Fern Hollow Bridge one year previously. The bridge was initially expected to remain closed for at least four months for emergency repairs costing $1–2 million, but officials announced a three-year closure for large-scale rehabilitation in March 2023.^[10][33] As of July 2024, construction is planned to begin by the end of the year and last until fall 2026. The project will cost about $50 million and includes replacement of the deck and steel supports, rehabilitation of the truss, piers, abutments, railings, and pylons, and new paint. The sidewalks will also be widened and one of the westbound traffic lanes will be replaced by a two-way bike lane.^[34][35]
