Thornton Creek Confluence Updates

Construction Update

 

The project reached a milestone earlier this week when the north branch of the creek was reconnected to the main stem, marking completion of in-water work on the north branch and main stem. This brings us one step closer to project completion and also means one less bypass pump running on the construction site. Over the next few weeks, construction activities will include:

 

  • Cleanup and dewatering of the site following heavy rainfall this week

  • Concrete pouring and formation of the bridge abutments

  • Creation of the south branch creek, west of 35th Avenue NE
