I think this is one of those streets that often gets forgotten or people struggle to place exactly where it is. Here's a 1950s view looking up Lower Temple Street towards St Phillip's Cathedral. Think you can just about make out the passageway (Burlington ?) on the right which ran behind the shops on New Street. At this time it looks like it was only one-way for traffic at this point, the flow being only allowed down onto Stephenson Street/Navigation Street.
