Work on the Ottawa water main improvement project on Joliet Street and Ottawa Street between Jefferson and Jackson street in downtown Joliet will begin on Monday.

The work for this project will proceed in two phases, the city said in a new release.

The first phase consists of water main replacement on Ottawa Street with an anticipated completion date by Nov. 17. The second phase consists of water main replacement on Joliet Street and has an anticipated completion of Dec. 29.

The project will require significant traffic control to be installed for the duration of the project, according to the city’s release. Most of the work is planned for daylight hours and traffic will be able to travel through the construction zone, the city said.

However, full road closures and night work will be required periodically throughout the project. Detour routes will be posted.
