Normally the excavation is 'traditional' i.e. dig a trench and chuck the ducts in and back-fill it. If it's an extremely busy road which can't be closed or have lane restrictions imposed on it then I have known situations where thrust-boring has been used. To be honest I really don't know how the cost compares, though.

If ntl want to increase their customer base, at some point the networks will have to be extended as they will reach saturation point sometime, but what sort of timescale is involved is anyone's guess. Perhaps they're going to wait to see what new technologies develop which could make the provision of service a lot cheaper.
