Anyone who decides to use the subways this weekend can expect a diversion, as 14 train lines will see service changed.

Meanwhile, No. 7 train riders are getting respite from a 12-weekend construction scheduled that has forced the MTA to cut service on large swaths of the line, particularly into Manhattan. The next round of weekend construction is planned for Feb. 28 to March 2.

Service changes last from 11:45 p.m. Friday to 5 a.m. Monday, unless otherwise stated.

Updated: Service on the 1 line has been postponed. Thanks MTA!
