Dominion Virginia Power has completed much of the work to improve electrical service to the Route 14 corridor of Gloucester into Mathews.

Daisy Pridgen, a spokesperson for Dominion, said the project is expected to be completed by March 1, 2017.

All 150 steel poles have been set, Pridgen said, and eight of the 10 miles of electrical line have been placed. The project involved erecting taller poles to carry electric lines from the Wan substation near Cow Creek Mill Pond on Route 14 into Mathews County.
