|Route outline (key)|
The B6166 was a link road in central Yorkshire.
In the 1960s, following the construction of the A1 Boroughbridge bypass, the entire of the B6166 (except for the short section now inside the bypass) was upgraded to Class I status, becoming the A6055. More recently, the upgrading of the A1 to motorway status in the 1990s moved the A1(M)/A6055 junction further south and so the original section of the B6166 north of Minskip is now unclassified.
