Long Street in Woolston and there is nothing on the library website for this street. I have searched Papers Past and there are articles mentioning this street as far back as 1915 so it isn’t a new street. The council advised that they would be doing riverbank protection work here and this was in 1930. I couldn’t find any reason for the name. The street actually looks like an extension of Barton St but there are articles about both streets at the same time.
The street isn’t long and it runs beside the Heathcote River and has a business at one end and houses at the other end. They are mostly older houses in good condition. My only photo is of the end of the street overlooking the river.
OK I give up as I just can’t find any information about how this street got named. I did find two men with the surname of Long who lived in Christchurch at the right time but can’t find any evidence that they lived near here.
