The baseball season is over in Chicago, but the demolition season is about to begin at Wrigley Field.

Crews will start tearing down the ballpark’s iconic bleachers Monday.

Both sections above left field and right field will be rebuilt after the stadium walls are moved out.

The center field bleachers will remain intact.

The Cubs plan to have seven new outfield signs up by next opening day.

That includes two video boards.

Cubs officials say they’re on a tight schedule, so every part of the project has to be completed on-time.
