Three Brooklyn R train stations are set for renovations under a multimillion-dollar project.

Work is set to begin on the 53rd Street Station next Monday.

Service in both directions will be suspended for six months while new platforms, floors and lighting are installed.

The station will also get new signage, digital real-time arrival signs, and wall and ceiling repairs.

The Bay Ridge Avenue station will close for the upgrades starting April 29, and the Prospect Avenue station will close June 5.

The upgrades are part of a $72 million modernization project announced by Governor Andrew Cuomo last year.
