Improve alignment of A20 eastbound carriageway at Union Lane junction

Revert incorrect changes of highway=tertiary to highway=service in changeset 50973528 (from August 2017)

Add another unmarked crossing and traffic cushion to Sandwich Road

Sandwich Road is single-carriageway (the hatched markings don't make it dual carriageway).

Improve mapping of extent of A1307 contraflow near Swavesey

Add mapped access into the bus station from Castle Moat Road

Roundabouts at New Ellington junction not yet fully open (again). This partially reverts 78159155 and 78140156.

Improve alignment of the (now closed) temporary A14 carriageways from GPS info - this might help with aligning the current contraflow.

Fix tag typo (consruction->construction - should have read the warnings before uploading)

Roundabouts at New Ellington junction not yet fully open

Second WB Swavesey slip open, with number 24B, and A1307 currently in contraflow

Add ref=A1307 tag between Alconbury and Spittals

Remove old A14(M) tag from Alconbury Spur. It's possible it should be named (either A1307(M) or A1(M)), but leaving it unnamed here for now.

New A14 EB exit slip at Swavesey is also opening this (Monday) morning

Add missing construction=primary_link tag to A13097 Spittals EB entry slip

Revert merging of embankment and non-embankment wys on A14 bypass in changeset 78120031

Brampton Hut and Spittals roundabouts are part of the A141 (so add a ref tag)

Revert A1307 under construction on Views Common to dual carriageway, and link up roundabout correctly, to match the plans I've seen

Fix some erroneous junction numbers between Swavesey and Girton introduced in changeset 78120031

Add missing construction=trunk tag to eastbound A14 bypass
