Some 57,000 homes and businesses in Scotland have gained access to super-fast broadband as a result of the £410 million Digital Scotland project.
BT engineers have so far installed more than 1,400km of cable on the mainland as part of the scheme, helping to hook up remote communities to the fibre network.
In addition, ten out of 20 sub-sea fibre optic cables have been laid, in order to ensure super-fast broadband becomes available on the Scottish islands.
At present, the Digital Scotland network is passing around 3,500 homes and businesses every week.
The rate of progress is expected to increase further in the coming weeks as the rollout gathers pace.
Brendan Dick, BT Scotland Director, said the firm's Scottish projects are "on a scale not seen anywhere else in the UK".
"We’ve had a lot of groundwork to do and we’re still in the early stages," he explained.
"At BT Scotland, we’ve recruited dozens more engineers to help deploy and install fibre services, we’ve laid hundreds of miles of new cables and we’re currently seeing the network extend its tentacles under the sea to the islands."
Mr Dick claimed that progress is "highly visible" and the new network is really taking shape.
He said BT's engineers are "doing a sterling job" and the company is proud to be involved in delivering vital infrastructure for Scotland.
