Project Completed
Back in September, construction wrapped up on the Red Hill Sewer Improvements Project. Crews are focusing on the very last few items to officially complete the project. Some items include landscaping and replacement of a section of waterline by Red Hill Avenue and Parkway Loop/Industrial Drive (see the latest construction alert and information above).
We want to give a big thank you to the community for showing us patience and understanding during construction. We understand it is never easy for those who live, work or commute in the area.
The photo below shows a portion of the construction work that took place at the intersection of Red Hill Avenue and Mitchell Avenue over the summer. It’s hard to imagine that the roadway looked like this only a few months ago.
