context_page_description: The A14 is a trunk road in England, running 127 miles from the Port of Felixstowe, Suffolk to its western end at the Catthorpe Interchange; a major intersection at the southern end of the M6 and junction 19 of the M1 in Leicestershire. The road forms part of the unsigned Euroroutes E24 and E30.
context_section_description: From the A12 west of Ipswich to the M1/M6 junction, the A14 is part of (but not signed as) the E-road E 24. From Ipswich to Felixstowe is part of E 30.
  The numbering of the A14 is inconsistent with the national road numbering scheme, as it begins in zone 5 and crosses through zone 6 on the way to zone 1 east of Huntingdon to Felixstowe. The road is concurrent with the A12 road from the Seven Hills Interchange to the Copdock Interchange which forms the Ipswich Southern bypass and with the A11 road between junctions 36 and 38.
  Until the opening in 2019 of the Huntingdon bypass, there was some confusion as to the identity of the section of road between the A141 junction at Stukeley (Spittals Interchange) and the A1(M). The Ordnance Survey 1:25000 map showed the A-road section as part of the A14 and the motorway section (between the B1043 junction and the A1(M)) as the A14(M). However, some official documents, including the 1993 statutory instrument which authorised the motorway upgrade, referred to it as the A604(M). The same confusion appeared on the former Highways Agency page about the 1996-8 upgrade to the A1(M) between Alconbury and Peterborough. The signs on entering the motorway section, unusually, show a large "start of motorway" symbol with no number, and there are no driver location signs confirming the route number.
  Following the opening of the Huntingdon bypass, the former A14 between the A1(M) and the Cambridge Services at Swavesey has been renumbered A1307, with the section through Huntingdon itself closed for the time being. Therefore, the "Alconbury spur" of the former A14 trunk route finally carries a unique road number again, in the form of the A1307. The official number of the former A14(M) stub is not known: some claim it is still A14(M), as the new road did not become a motorway in the end; others claim A604(M), although the lack of an A604 makes this hard to believe; and others still claim it is just a spur of the A1(M), carrying the same number. 
  East of the Girton Interchange with the M11 at Cambridge, the A14 used to be the A45, and much of the long-distance traffic further west had previously used the A45 route. The section between Cambridge and Kettering used to be the A604, apart from a short section near Kettering that used to be part of the A6. The road which was the A14 until the late 1980s is now the A1198 between Royston, Hertfordshire and Godmanchester.
