Unique Street Reference Number 80301154

Unique Street Reference Number 80301154 covers more than one named or numbered road. The longest section is, according to Ordnance Survey OpenNames, Ashford Lane in Amersham.

Note: a USRN is an operational identifier and is unique to a highway authority. Where a road crosses a highway authority boundary, therefore, it will have different USRNs in different authorities, even if it has the same name and number.

Roads operated by national highway authorities (eg, Highways England) will also have separate USRNs for the road as a whole and for each subsection within each local highway authority that it crosses.

Unfortunately, there is no Open Data source which links all known USRNs to street names and numbers. The names and numbers, if any, shown here are, therefore, derived by cross-referencing the Open USRN database with other Open Data sources such as OS OpenMap Local, OS OpenNames and OpenStreetMap. This is not 100% reliable, and doesn't work at all for some USRNs. So the data shown here may not necessarily be correct. See Limitations of the Data for more detail on this.
