All you have to do is tap on any of the 368 NYC subway stations labeled on Google Maps to see whether there are any planned changes that are expected to affect those stations at that time. These alerts will also appear in the step-by-step transit directions pointing you wherever you’re going so you can factor in the extra time you need to get to your destination due to any additional transits you may have to take.
The feature is currently available on the Google Maps for Android app as well as maps.google.com. Check it out and let us know what you think.
