city government took over the BMT's operations on June 1, 1940, and the IRT's operations on June 12, 1940. Transfer passageways between the three stations were placed inside fare control on July 1, 1948. The Eastern Parkway Line platforms were extended eastward in 1964, allowing the station to accommodate 10-car trains. In 1976, with funding from the Exxon Corporation, the Broadway–Seventh Avenue Line station, as well as three others citywide, received new "artfully humorous graffiti" murals and artwork. Local designer Samuel Lebowitz received $5,000 to "improve the level of lighting in an exciting and light hearted way." Some "multicolored animated neon signs" were placed underneath transparent plastic screens; such signs included "an abstract eye that winks every five seconds" and another that looked to be "blow[ing] smoke rings." In 1982, the Urban Mass Transportation Administration gave a $66 million grant to the New York City Transit Authority. Part of the grant was to be used for the renovation of several subway stations, including Borough Hall's IRT platforms. On weekdays between August 2, 2013 and September 15, 2014, this station served as the northern terminal of the Brooklyn half of the divided R. Service ran in two sections: one section between Forest Hills and Whitehall Street–South Ferry, and the other between Court Street-Borough Hall and Bay Ridge–95th Street. This change was necessary to repair damage on the Montague Street Tunnel resulting from Hurricane Sandy. In June 2018, part of the Eastern Parkway Line station's ceiling collapsed, injuring a bystander. The collapse necessitated expensive emergency repairs that would set the MTA back $8.3 million. A report found that the staff sent to inspect the station verified the defect existed in 2017, but underestimated its severity due to a lack of expertise in terracotta ceilings, nor was the issue escalated to engineers who were familiar with terracotta. The ceiling was over 100 years old. The MTA report suggested that special care be taken in the inspection of the thirteen subway stations that have terracotta ceilings due to the different properties when compared to concrete or steel. In November 2022, the MTA announced that it would award a $106 million contract for the installation of additional elevators at the Borough Hall station complex, making the Eastern Parkway Line platforms fully accessible. The contract included one elevator from the mezzanine to either of the Eastern Parkway Line platforms, as well as one elevator from the
