the final 1.2 mile section of the a14 'spur' from the junction with the b1043 near huntingdon to the a1(m) at alconbury has many inconsistent designations. it is the only section of the original a14 (a1198 road) that still bears that a14 designation; it was renumbered a604 for a period prior to the construction of the current a14. the scheme page on the highways agency website for the 'a1(m) alconbury to peterborough' scheme carried out in 1996–1998 refers to it as the a14(m), but the map page linked from that page marks it as the a604(m). the statutory instrument for the construction of the road in 1993 also refers to it as the a604(m). neither the a14(m) nor the a604(m) designation is used on the ground; heading onto the a1(m) heading north there a bare 'motorway' sign just past the b1043 exit without any number (see photo in the top right of this page). however, when heading south along the a1 it is signed as 'a14'. online mapping is also inconsistent – the highway agency mapping (which uses navteq data) refers to it as the 'a14(m)', bing maps (which also uses navteq mapping) shows it as motorway without any designation and yahoo maps (which uses navteq data) shows it as motorway and as the a1(m). google maps (which uses teleatlas data) shows it as a trunk road called a14.
