CHICAGO — Streets from Edgewater to Rogers Park will be torn up this summer to replace century-old water mains, officials said.

The project that might cause the biggest headache to residents and motorists is planned for busy Bryn Mawr Avenue, with work expected to begin next week.

Ald. Harry Osterman (48th) said the water main replacement would be broken up into three phases between Kenmore and Glenwood avenues.

In Rogers Park, 12 blocks of mains would be replaced, Ald. Joe Moore (49th) said in an email to constituents this week.

Work has begun on these streets, according to Moore:

• Lakewood Avenue from Devon to Arthur avenues

• Magnolia Avenue from Devon to Arthur avenues

• Arthur Avenue from Sheridan Road to Glenwood Avenue

Work will begin this month on these streets:

• Lakewood Avenue from Farwell to Morse avenues

• Paulina Street from Lunt to Greenleaf avenues

• Greenleaf Avenue from Ashland Avenue to Clark Street

• Farwell Avenue from Sheridan Road to Ashland Avenue

The water main work is expected to be completed by the end of September, Moore said.
