Britannia, Bank Lane, Irlam O'Th Height, Salford. (c) Salford Pubs of the 70s flickr .
The original Britannia stood at the junction of Manchester Road and Bolton Road beneath the modern-day Irlam O'Th Height roundabout. It was pulled down in 1975 and a replacement Britannia was built by Wilsons Brewery round the corner on Bank Street. It was a unique-looking, hexagonal-shaped estate pub with the lounge and games room on the upper floor and accomodation below, due to the dip in which the pub was built, and drinkers entered the pub by a short footbridge. The Britannia opened in 1977 and closed just 17 years later in 1994  and was pulled down sometime after 2001 as an Inntrapeneur Pub Company (Chef & Brewer) house, according to council records. The postcode of the old boozer was M6 7LP which pulls up this location, so I suspect the pub was here where the new housing is.
