The most authoritative document is the Special Road order, which
indeed calls it the A604(M). None of this is reflected on the ground
however. I'd suggest tagging it northbound as A1(M) and southbound
as A14 as that would more accurately reflect what is signed.
I have reviewed the information on pathetic motorways for the
Wikipedia article, however that is very much a secondary source. All
the Wikipedia references I have used for this are primary sources
except for the photo of the motorway sign heading north which does
come from that site.
I think it would be a mistake to have different references for each
carriageway. I also think it is definitively a motorway classification
and both carriageways should be tagged as such. Calling it the A1(M)
seems strange when that is what it isn't except on some Navteq
mapping. If one will accept a long motorway-link for the road in
question then that seems like a reasonable compromise. Happy to hear
other views though.

There is general confusion about the appropriate reference for the
A14 spur between the last exit near Alconbury heading north and
the A1(M). Here is a summary of the issues as outlined on the
Wikipedia article:-
"The final 1.2 mile section of the A14 'spur' from the junction
with the B1043 to the A1(M) at Alconbury has many inconsistent
designations. The scheme page on the Highways Agency website for
work carried out in 1996-1998 refers to it as the A14(M)[1] however
the map page linked from that page refers to the same section of
road as the A604(M).[2] The statutory instrument for the
construction of the road in 1993 refers to it as the A604(M).[3]
The A14(M)/A604(M) designation is not used on the ground; when
heading from the A14 spur onto the A1(M) heading north there a
'motorway' sign just past the B1043 exit without any number of on
(see photo in the top right of this page)[4] however when heading
south along the A1 it is signed as 'A14'.[5] Online mapping is also
inconsistent - the Highway Agency mapping (which uses Navteq data)
refers to it as the 'A14(M)',[6] Bing maps (which also uses Navteq
mapping) shows it as motorway without any designation[7] 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.[8]
I have chosen to tag it as a motorway-link without any associated
reference (it was tagged as the A14(M) until I changed it to A14 as
'trunk' but that doesn't seem right).
I think using motorway-link avoids creating any confusion for
routing purposes by showing references that are not provided on the
roadside signs. There are also arguments for tagging it in any of
the other ways that are described on the A14 article! Should we add
an 'alt-ref' tag, and if so what should be in it, and should we add
a note with a link to the Wikipedia article or the the OSM wiki?
