If your travel plans this Memorial Day weekend include driving, you’re not alone. AAA predicts that 34.6 million Americans will drive to their holiday weekend destinations this year, marking the third consecutive year of growth and an increase of 2.4 percent over 2016.

“The expected spike in Memorial Day travel mirrors the positive growth seen throughout the travel industry this year,” Mary Maguire, a AAA Northeast official, said in a statement. “Higher confidence has led to more consumer spending, and many Americans are choosing to allocate their extra money on travel this Memorial Day.”

We asked the Massachusetts Department of Transportation, AAA Northeast, and Waze to help us identify when to hit the road this holiday weekend. Their mantra? Leave as early as possible to avoid the biggest rushes out of or back into Boston.
