An additional elevator connects the northbound Orange Line platform with the eastbound Blue Line platform and southbound Orange Line platform, while an accessible ramp connects the westbound Blue Line and northbound Orange Line platforms. In May 2020, the MBTA awarded a $8.7 million design contract for accessibility renovations at State and . The work at State includes two elevators at the City Hall entrance, replacements of two existing elevators, and renovation of the Milk Street entrance. Design work reached 30% completion in 2021 and 75% completion in 2022. Public art The station has several works of public art: The passageway to the southbound Orange Line platform was painted with rainbow colors by Robert V. Kennedy in March 1972. The painting and corresponding timed lighting (no longer in use) cost $9,000. Kennedy won the 1971 competition to design artwork for the station. Polychrome painted star, a 1975 enamel-on-porcelain mural by Toshihiro Katayama, is located in the passage to the eastbound Blue Line platform. A 1987 black steel gate by Albert Paley is located next to the Old South Meeting House headhouse.

However, neither these nor the large center-entrance cars introduced in 1917 (which were designed for multiple unit operation) could fully handle the crowds. In 1921, the Boston Transit Department (BTD) - the
