I've been discussing the usage of "in Church Road" over "on Church Road" with my colleagues in a sentence such as "The supermarket is in Church Road". Whilst it is overwhelming clear that "on Church Road" is the favoured option in this discussion, it remains unclear as to whether the use of "in Church Road" is completely uncommon or incorrect in this context.
The case regarding "Church Street", we feel, is clearly a simple case of who is speaking, but "Church Road" is presenting us one or two problems.
Any help?
