Whether you plan to stay or go, you’re bound to hit some Memorial Day weekend traffic. More than 41.5 million people are traveling this weekend—nearly a 5 percent increase from last year and the most in more than a dozen years, according to AAA.

So, expect nothing less than a nightmare on the roads during peak travel hours. Delays could be three times longer than normal in some cities, according to INRIX, a global transportation analytics company. In Chicago, the heaviest traffic, which could double your driving time, is expected between 4:00 and 6:00 p.m on Friday.

CTA and Metra

If you’re staying in town and heading to the Cubs game at Wrigley Field, the CTA will be adding extra service on the Yellow Line, Red Line, and bus lines No. 80 and No. 152. Also, the CTA and Metra will run on a Sunday schedule on Monday, Memorial Day.

O’Hare and Midway airports

Flying out for the long weekend? Things are looking good as good weather graces Chicago. Delays at both airports are 15 minutes or less with 1 cancelled flight at Midway and 11 at O’Hare as of Friday at noon.
