Good morning, commuters! This week kicks off with humidity, warmer temperatures and the chance of an isolated shower, according to the Capital Weather Gang.

The biggest change to this morning’s commute is happening on New York Avenue. Beginning today, reconstruction of the bridge over the tracks carrying trains into Union Station will turn the bridge’s six lanes into four available lanes.

The District Department of Transportation says to expect delays of 15 to 30 minutes, but congestion on this stretch is already a major headache. Commuters can try out some alternate routes or apply to a program paying people to stay away.

We’ll be rounding up any headaches, issues or problems we hear about on the roads this morning. Let us know anything you see out there — tell us in the comments below or via Twitter (@DrGridlock).
