Dock street in Edgartown will be partly closed to vehicle traffic for the next three weeks as a project gets under way to replace an underwater electric cable in the harbor channel to Chappaquiddick. Construction crews began setting up large equipment this week, and drilling is set to begin on Monday.

Chappaquiddick ferry traffic will unload onto Daggett street, which will be two-way during the construction project. Dock street will be closed from the Mayhew Lane intersection to the ferry during construction.

While NStar is replacing the damaged cable, Comcast is working with the electric company to provide cable and Internet service on Chappaquiddick.

Town administrator Pam Dolby told the town selectmen at their weekly meeting Monday negotiations were going well.

In other business, selectmen awarded Ryan Smith and Edward B. Gentle two lots at the fishermen’s depot at the old landfill. The depot is used to store equipment and boats by fishermen who do not have access to the inner harbor.
