The next step in the planned renovation of Wrigley Field is underway.

Crews will shut down Sheffield Avenue between Addison and Waveland Wednesday beginning Tuesday to relocate water lines, as well as gas and sewer lines, under the street. The closure is expected to remain in place for two to three weeks.

A letter sent by the Cubs to area residents noted the utility companies did not expect any major service disruptions. Fencing also will go up around the CTA Red and Purple line lots adjacent to Clark Street and Waveland Avenue to facilitate the work being done there.

"We look forward to the start of these exciting plans for renovation and expansion of Wrigley Field," the letter to fans read. "We appreciate your support and look forward to continuing to work with you to make Wrigleyville a great place to live, work and visit."

Sheffield Avenue was closed in August as trees and bricks along the street were pulled up so utility companies could begin relocating gas and sewer lines. Construction also began on parking lots surrounding the stadium.

After the season is over, work will being on the bleachers inside the stadium, with completion scheduled by 2015 Opening Day.

According to a letter the Cubs sent to area residents, current parking lanes on Waveland and Sheffield will be removed and the team will offer free parking on non-event days in the Green Lot at 1126 W. Grace. Residents in the area bordered by Addison on the South, Racine/Clark to the West, Irving Park on the North and Wilton on the East can fill out a neighbor parking application at 3721 N. Clark and receive a sticker to allow Green Lot access.

But some area residents are wary of the additional traffic problems the closures will bring.

"You have cars going by trying to cut off and trying to go around, and it's just really inconvenient for pedestrians and also kind of dangerous," said Joan Duron, who works nearby.

The Cubs plan to pump $500 million into renovations at Wrigley Field over the next four years. In addition to new lighting and several signs in the outfield, the improvements will include an expanded players clubhouse underneath the parking lot on Clark Street.

"I think it's good for the Cubs. It's gonna make them more competitive, I hope," Cubs fan Charlie Thayer said.
