Trench paving continues next week

This past week, the water main trenches were repaved on Henry Law Avenue, Washington Street, and Main Street. However, the trenches for individual water connections into the new main still need to be repaved. That work will continue next week, from Monday, Sept. 20 through Wednesday, Sept. 22. 

For contractors to complete paving, residents and businesses should expect the following disruptions:
 
  • A section of Henry Law Avenue near the Central Avenue/Washington Street intersection will be closed for a few hours Monday morning, Sept. 22. Parking will also be restricted in that area. Traffic will be detoured via Williams Street.

  • Parking will be restricted on Washington Street from Henry Law Avenue to Main Street Monday and Tuesday, Sept. 20 and 21. Expect a lane reduction through the paving area.

  • Inbound and outbound Portland Avenue will be closed for short durations to allow paving on Tuesday or Wednesday, Sept. 21 or 22.

  • Parking will be restricted on Main Street from Washington Street to Broadway on Tuesday and Wednesday, Sept. 21 and 22. Expect a lane reduction through the paving area. 

Once paving is complete, the crews will raise water valve boxes throughout the project area. This work is anticipated to occur Thursday and Friday, Sept. 23 and 24. This will require rolling lane closures as crews move from valve box to valve box. No parking restrictions are required.

The work schedule may change depending on weather conditions.
About the project
The Washington and Main Water Improvements project replaced 3,000 feet of critical water main infrastructure under Washington Street and Main Street, some of the oldest water distribution pipes in the City of Dover that were installed in the late 1800s.

The contractor installed 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 has had significant traffic impacts and limited durations of water shutoff as infrastructure is replaced. The project remains on schedule for season completion on Sept. 18, 2021. A complete street paving overlay will occur in the spring of 2022.

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. There are areas of uneven roads and sidewalks, so please use caution driving, riding bikes and walking in the area.
