What do you call the principal shopping street in a town? I’ve always thought of the High Street as distinctively British but Main Street as distinctively American. There are, though, some Main Streets in parts of England. I recently came across some in the north of Nottinghamshire, for example in the villages or hamlets of Mattersey, Styrrup, Harworth and Clarborough.
On the other hand, other nearby places have a High Street. These include Everton, Gringley-on-the Hill and (just across the county boundary in South Yorkshire) Bawtry.
There is also a Main Street in the villages of Heslington and Fulford, on the outskirts of York.
I don’t know whether Main Street is specific to particular localities in Britain. Nor do I know whether the term Main Street used in the US was created (or recreated there) or whether early settlers imported it from their localities of origin in Britain.
One north Nottinghamshire village near the villages mentioned above is Scrooby, birthplace of William Brewster. Brewster was one of the pilgrim fathers who sailed to America on the Mayflower in 1620. The principal road running through Scrooby is neither a High Street nor a Main Street, though. It bears the name of a road of national significance, not just local significance: the Great North Road, which ran from London to Edinburgh.
