From the MTA:
Customers may visit our website at www.mta.info and check out The Weekender, which takes over the front page of MTA.info each weekend. The Weekender makes it easy for subway riders to visualize exactly how weekend work will affect subway service. In addition, TripPlanner+ provides travel information that takes weekend service diversions into account.
The Weekender for Mobile in the Apple app store is available now for iPhone, this free-to-download app shares the same features as the desktop version, including a subway diagram that displays the service to be provided each weekend, and all service changes. Using the most-popular features of the iOS system, users can pinch or expand the map to multiple zoom levels, and tap to choose one of three ways to view service diversions: Service by Line, Service by Borough, Service by Station at http://mta.info/apps/weekenderApp.html
These weekend changes are necessary because of capital construction work on the MTA New York City Transit subway system. This work is part of NYC Transits ongoing Capital Rebuilding Program aimed at upgrading and maintaining our tracks, stations and signal systems in order to continue to provide our customers with safe and reliable service. For more information on the 2010-2014 Capital Program log on to www.mta.info/capital. Customers who rely on these lines should allow for additional travel time.
