Midcities Sanitary Sewer Improvements

News and Updates...

This project is complete!

All road closures have been removed.  No further updates will be provided.

Beginning May 8, 2023, the City and County of Broomfield and their contractor, BT Construction, Inc., will close Interlocken Boulevard between Flatiron Boulevard and Interlocken Loop to be able to excavate in the street to remove and replace sanitary sewer piping and manholes.  The closure is necessary to upsize the sewer system to handle flows from new development in the area.  Detour routes will be posted, and emergency and business access will be maintained.  Final asphalt pavement restoration and restriping are underway and anticipated to be complete by July 14th at which time the remaining traffic control devices will be removed.  Landscape restoration is expected to be complete by August 1st.
