Clearly visible is the Dean Clough Mill (where the words Crossley Kosset are visible). The bus appears to be a 681, a service to Bradford that still runs today (2017).
This scene is almost unrecognisable from the Northgate of today as many of the buildings have since been demolished. The church building on the right appears to be Northgate End Chapel, built in 1871 and demolished in 1982.
This is on Northgate, just before North Bridge, where the traffic lights are now, across from the end of North Bridge Street. The road that the van and car are heading towards is Cross Hills
