Can anyone tell me when Burlington Street was demolished? MY dad lived there and in WW2 he sent letters to his mum there from India,Always complaining about the beer being warm.

There were 2 Burlington Streets , one near Wigan centre, off Greenough Street , the other in Hindley approx 4 miles away.
(which still exists).
Assume you mean the Wigan centre one ?

yes the one near central park

Yes the Wigan one . Anybody know?

Second on the left up Turner street,towards St.Georges school.

In answer to your question kameras, I believe, that most of that area around Burlington Street was demolished in the early 1970s.
I am not sure of the exact date, but that housing area on the left as you went up Greenough Street had been virtually cleared of houses by the mid 1970s.
Around 1975, the fairground was held on that land. So, most of the houses, if not all, had been demolished by this time.
I am quite sure, many of the houses were still standing with families living in the properties in 1971/2.
I think, the first empty houses ready to be demolished were the few which were at the side of the path of the River Douglas. These few houses had front gardens and they stood at a much lower level to the houses on Burlington Street; to get to these few houses you had to go along the path of the River Douglas, so you could not get to them with a car.
I am sure, they started demolishing from the River Douglas end and moved up to Scholes. So, Burlington Street may have been one of the first to be demolished.
Please understand, that this is from my memory of the place.
I would give a guess at 1973.
