Community Broadband Network Updates

Updated March 21, 2025

Residents may notice crews and trucks from Kelly Cable continue working in the North Community and Western Area neighborhoods as part of the initial phase of Los Alamos County’s Community Broadband Network project. These teams will assess existing county-owned conduit infrastructure for possible use with the CBN through April 2, working Monday through Friday from 8 a.m. to 5 p.m.

While we expect minimal impacts, we kindly ask residents to avoid parking in work zones and follow these guidelines when crews are present:

  • Park in driveways whenever possible.
  • If parking on the street, use the opposite side from where crews are working.
