Around 2000, the MBTA outfitted the Green Line platforms with portable lifts as a temporary accessibility measure to serve the new low-floor Type 8 streetcars. A $15 million project to build raised low platforms at Park Street and began in 2001. The work at Park Street was done in segments to allow service to the station to continue during construction. Construction was completed in 2003. New elevators from the surface to the westbound Green Line unpaid lobby and from the westbound Green Line platform to the Red Line island platform opened on December 21, 2012. They were built, and two other elevators rebuilt, as part of the 2006 settlement of "Joanne Daniels-Finegold, et al. v. MBTA". In early 2019, the MBTA accepted bids for a $11.8 million renovation of Park Street station. The project includes replacement of all wayfinding signage and lighting, as well as the reopening of the 1976-closed Temple Place entrance. Work began in April 2019 and was completed in December 2020. The elevator between the Red Line lobby and platform will be replaced in 2022-2024 as part of accessibility improvements at Downtown Crossing.
