If you're planning on using the subway this weekend, get ready for some service disruptions.

Weekend track maintenance will affect 14 lines starting Friday night.

Here are some of the changes:

Downtown No. 1 trains will run express from 145th Street to 96th Street.

No. 5 trains are suspended in both directions between Dyer Avenue and East 180th Street.

And there's no L service either way between 8th Avenue and Lorimer Street.
