ROGERS PARK — This isn't the first time residents living along the Red Line in Rogers Park have been warned of noisy, nighttime construction.

The CTA has distributed a notice to the neighborhood, alerting residents to expect noise — like "metal-on-metal hammering" and "crunching rock" — over the next few weeks along the Red and Purple lines between the Granville and Howard stations.

CTA spokeswoman Catherine Hosinski said the work wouldn't delay service or cause trains to skip stations, as they have in the past. She said crews were mostly focusing on shoring up the northbound Purple Line tracks.

Hosinski said late-night riders might experience their trains slowing down while they pass through work zones.

Work begins at 9 p.m. and ends at 5:30 a.m. the next day on the following dates: July 22-24, 27-31; and Aug. 3-7, 10-14.

The CTA warned residents to expect the following from Granville to Howard stations:

• Engine noise from diesel-powered track maintenance equipment

• Beeping from backup alarms on track maintenance equipment

• Crunching rock

• Metal-on-metal hammering

• Light in the work zone

• Restricted access to some alleys

Construction in the 1300 block of West Farwell Avenue has gotten on residents' nerves before. For the past two years, crews have been building an electric substation there that will boost power to the tracks and increase train speed.

Residents experienced "extremely loud" noise and crew members parking on their sidewalks.

Hosinski said the substation should be completed within the next three weeks. The east alley, connecting Pratt Boulevard and Farwell Avenue, which has been closed during construction, reopened this month.
