In July 2017, the Metropolitan Transportation Authority started rebuilding two parts of the Myrtle Avenue Line, the approaches to the junction with the BMT Jamaica Line (which lasted until April 2018, requiring suspension of service between Wyckoff and Myrtle Avenues), and the Fresh Pond Bridge over the Montauk Branch in Queens (which lasted from July to September 2017). This work was undertaken in preparation for a reconstruction of the BMT Canarsie Line tunnels under the East River, which took place between 2019 and 2020. Regular service resumed on April 30, 2018.
