No, Clark Street Station isn’t open yet. The MTA site says “through April 2022″ — that gives them two more days.
Apart from there being no late night R service, although N trains should be running normally there are no planned cancellations or route changes directly affecting service at local stations this weekend. Those planning to visit the
Brooklyn Botanic Garden, the Brooklyn Museum, or the main branch of the Brooklyn Public Library should know that, while getting there by subway (2, 3, or 4 trains) should be no problem, no Manhattan bound trains will stop at Eastern Parkway-Brooklyn Museum, Grand Army Plaza, or Bergen Street. To get back from these places, you’ll need to take a Brooklyn bound train to Franklin Avenue-Medgar Evers College and catch a Manhattan bound train there.
The following work week — Monday, April 25 through Friday, April 29 — the only change is that, again, there will be no late night R service, but N trains should be running normally.
Those traveling to or from Bay Ridge should know that, during this entire weekend and during late nights the following week shuttle buses will replace R train service between the 9th Avenue station and 95th Street in Bay Ridge.
These are the planned service changes directly affecting service at local stations. Always check MTA Info for unplanned service changes that may affect local service or service on other parts of your trip, or for planned service changes that affect stations to or from which you may be traveling.
