Under Construction: Crews are burying fiber optic lines to customer homes and businesses. This part takes time, patience and good weather. Once the lines are in the ground, a new crew moves in to splice them all together. Expect utility locating, temporary utility flags & paint, dirt work, vault installation, boring machines and contractor vehicles. This step in the process can take a few months to over a year before the network is fully constructed and ready for all of the customers in each predetermined area.
