The biggest problem for commuters heading into the Tuesday morning rush hour remains power outages and debris. With hundreds of thousands of power outages still impacting the region, travelers can expect to encounter dark traffic signals as they head to work. Fallen debris can block roadways and cause massive delays.
First, as always:When you come to an intersection and the traffic signals aren’t working, treat this as a four-way stop.
You should also expect to hit added delays and congestion you wouldn’t always hit heading to work. Add some time to your commute to allow for delays and for potentially taking detours.
We’ll be monitoring the morning commute and reporting anything we hear. If you see traffic problems, blocked roadways, dark traffic signals or any other problems, let us know in the comments section below or by tweeting @DrGridlock.
