Hennepin/Lyndale Avenue Reconstruction Project
City Sanitary Sewer Project is Underway
Thanks for your patience as we work through some challenges (PDF) on the Hennepin/Lyndale sanitary sewer repair project. Unforeseen underground obstructions have caused delays and have resulted in a need to utilize different construction techniques to complete the work.
Ideally, the crew would be traveling 40-50 feet per day. Some days have been as low as 3 feet. The crew needs to travel 350 feet to complete Phase 1 (PDF). At this time, they will re-open the Groveland intersection and move on to Phase 2, which is another 400 feet.

- Due to weather and other delays, the Groveland Avenue intersection will unfortunately not be open by Thanksgiving.
- To make up some time, crews will be working this Saturday from 9AM to 6PM.
- The new pit has been started and is being set. They will start moving equipment in and will start full tunneling operations likely after Thanksgiving. At this time, we anticipate much more progress on advancing the casing and completing Phase I of construction. Phase I needs to be complete before the Groveland intersection is open.
- We have been coordinating with Holidazzle staff and will continue to do so as construction progresses. Oak Grove will not be closed until Groveland is open, so Oak Grove will certainly remain open the first weekend of Holidazzle. Visit the Holidazzle website for more information on event parking and access.
- In addition to finishing the new pit, next week the contractor will be testing the soil from the pit in front of St. Mark’s to the north, to see if there are similar obstructions for the next phase of work. If things are clear, construction should go a lot smoother and faster in this phase. The results of this testing will give a better indication of when Oak Grove will need to be closed and for how long.
