Renovation project at Wrigley in full swing

Construction equipment is starting to take big bites out of Wrigley Field's outfield walls.

The demolition of the historic ballpark's famous bleachers is part of a project to build a large electronic sign and six other outfield signs. Cubs spokesman Julian Green said Thursday that the field will be exposed for several weeks before the walls are rebuilt. On Saturday team officials along with Major League Baseball Commissioner Bud Selig took part in a ceremonial groundbreaking ceremony for the renovation project.

The work is part of the Cubs' privately funded $575 million renovation project. The Cubs started the project despite a legal fight involving owners of rooftop businesses across the street from Wrigley. Those businesses fear their views of the field will be blocked and they have sued the city.
