Periodic nighttime saw cutting begins in mid-July
Some additional night work/noise may begin in mid-July, when we expect to start pouring the concrete for the new southbound I-35E lanes between Little Canada and St. Paul. With concrete road construction, stress joints must be cut into the concrete while it is hardening and that window of opportunity closes approximately 12 hours after the concrete is poured during the day. Crews will try to avoid saw cutting at night but at times it may be necessary to ensure a successful finished product. The concrete pouring/saw cutting locations will vary between approximately mid-July and mid-August as the lanes are completed. Thank you for your patience and understanding during this work.
Noisy work at night in 2015 will be limited as much as possible, but may need to occur periodically during construction this year, particularly on I-35E between Maryland Avenue and Little Canada Road. Some noisy night activities scheduled for this construction season include:
- Demolition of the southbound I-35E bridges over Hwy 36, County Road B and Roselawn Avenue. Currently scheduled to occur in early May, this work will require road closures beneath the bridges. The contractor will be working around the clock to finish the work and reopen the roads quickly.
- Saw cutting concrete. With concrete road construction, stress joints must be cut into the concrete while it is hardening and that window of opportunity closes approximately 12 hours after the concrete is poured during the day. This work will likely happen in mid-to-late summer.
Nighttime construction or maintenance is any construction/maintenance activity occurring between 8:30 p.m. and 7 a.m. and within 500 feet of hospitals, senior living complexes, private residences, apartment buildings, businesses and hotels/motels.
Construction or maintenance activities that are generally prohibited during 8:30 p.m. and 7 a.m. include pile driving/removal, concrete pavement demolition, pavement sawing, concrete crushing operations and jack-hammering. However, there will be times when noise producing operations will have to occur at night because of the need for pavement to cure or be sawed, or lanes closures that allow access to the work area.
