I was in Derby yesterday, a new railway bridge is being built on London road, it is a year long project and is nearly finished, I spotted a BT van and trailer next to a large open JBP and they where pulling new fibre ducts for the new bridge.
I tried to have a chat with the man working the winch but was difficult because of the noise from the winch engine.
 He said they pull most of the fibre ducts in the night and also blow the fibre in at night, they are allowed to start 12.01pm and can do it without roadworks permission, so that's why I did not see anything about the fibre being put in in our village on the roadworks website  http://roadworks.org/  , but I did have a feeling it had gone in a few weeks ago when I noticed the dirt around the JBP lids in the direction of the exchange had been disturbed.

The actual glass fibre is never pulled (or pushed). 

What you witnessed being pulled into the standard ducting is the sub-ducting. (It looks like a thick black cable with a yellow stripe along its length.) It is into the sub-ducting that the fibre is then subsequently blown.

Ive several times now seen fibre being blown during the day around here.  I suppose it may perhaps have something to do with locality and how much the road may be obstructed during the process, but twice in the past year or so,  Ive had to cross over to the other side of the main road to pass the vehicle parked blocking the road, which contained that big reel of cable.

Around these parts we are generally discouraged from feeding them bread and the likes, even high fibre wholemeal.   It is just not part of their natural diet we are told, and can lead to other health problems.

Ah, just spotted, you said Duckts.      Sorry, thought of it and couldn't resist.  Back on topic, please.

As usual from my small number of brain cells I did not use the right words.

What he was pulling in was like a figure of 8 , black one tube green the other, looked like 5mm dia each tube , but overhaul size  about 20mm across .

Interesting. I wonder if (special agent) Walter has seen similar?

was in day also here and I am on a main road, however with that said the ducts here are below pavement not the road.

they dont need permission at night as is no noise.

I do not think it's a golden rule that they put it all in at night, maybe a day team and a night team .
You say no noise    if you could hear the noise that winch was making

I think it's to do with TV video networks.  There was/is a small TV studio down the road.
