About the project
The Washington and Main Water Improvements project is focused on replacing 3,000 feet of critical water main infrastructure along Washington Street and Main Street. These are some of the water distribution pipes in the City of Dover that are more than 125 years old.

The contractor will install a new ductile iron pipe that will provide reliable water service for the next 100-plus years. The project began on Monday, March 22, 2021. The six-month project is expected to have traffic impacts and limited durations of water shutoff as infrastructure is replaced. The project remains on schedule for substantial completion on Aug. 19, 2021 and final completion on Sept. 18, 2021.

This work includes street excavation, lane closures, and overnight water shutoffs in the downtown area. See the map below for the project area, or click here for the project page with project maps.

The City encourages pedestrians and motorists to be vigilant while moving throughout the downtown area and look for signs providing information about the project and sections of streets and sidewalks closed for construction. Uneven road conditions and sidewalks are likely to occur, so please use caution driving, riding bikes and walking in the area.
