Drivers should pay close attention to the construction signs when driving and parking downtown. Temporary water mains are laid along the curb and marked by construction barrels and signs. If water lines are hit by a vehicle, it could result in a rupture of the lines and damage to the vehicle.

Many steel plates will be placed on the sidewalks in the downtown area. Pedestrians should remain attentive and use caution when walking along sidewalks in work areas.

Report any damage to the temporary water system to police dispatch at 603-742-4646.
About the project
The Washington and Main Water Improvements project will replace 3,000 feet of critical water main infrastructure under Washington Street and Main Street. These are some of the oldest water distribution pipes in the City of Dover that are more than 130 years old.

The contractor is installing a new ductile iron pipe that will provide reliable water service for the next 100-plus years. The project began on March 22, 2021. The six-month project will have significant 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.
