This has been designated as ESSENTIAL. The nature of this work is to implement a fiber maintenance to relocate multiple cables and is required in order to proactively avoid outages due to a City mandated tri-level bridge demolition project. The estimated GPS location of work is South Water Street and North Stetson Ave in Chicago, IL. LAT: 41.886802 LONG: -87.624058 and LAT: 41.886823 LONG: -87.622520. The maintenance consists of multiple nights. An alternate/backup maintenance window has been scheduled in the event work is unable to be completed on the primary nights. Currently no services are scheduled to be impacted on the alternate night. Should the alternate night be deemed necessary, you will receive an updated notification advising which services will be impacted on that night. Please see the date and times of the alternate night below. Note: Due to a lack of slack in the cable, this work will be performed as a hot cut. Each buffer tube will be restored as quickly as possible, and the outage duration will range between 2 and 4 hours depending on splice restoration order. However, customers listed for an outage should prepare for an impact up to 6 hours during the maintenance window. Lumen sincerely apologizes for any inconvenience caused by this maintenance.

The nature of this work is to implement a fiber maintenance to relocate multiple cables and is required in order to proactively avoid outages due to a City mandated tri-level bridge demolition project. The estimated GPS location of work is South Water Street and North Stetson Ave in Chicago, IL. LAT: 41.886802 LONG: -87.624058 and LAT: 41.886823 LONG: -87.622520. The maintenance consists of multiple nights. An alternate/backup maintenance window has been scheduled in the event work is unable to be completed on the primary nights. Currently no services are scheduled to be impacted on the alternate night. Should the alternate night be deemed necessary, you will receive an updated notification advising which services will be impacted on that night. Please see the date and times of the alternate night below. Note: Due to a lack of slack in the cable, this work will be performed as a hot cut.

However, customers listed for an outage should prepare for an impact up to 6 hours during the maintenance window. Lumen sincerely apologizes for any inconvenience caused by this maintenance.
