Update bus relations for new A14 J31 slip road to A1307

A14 WB J30 entry slip road has remained open (access to Bar Hill entry slip only)

Improved EB aligment (it's moved north); add WB contraflow;add construction:highway=motorway tags

Revert 73856710 since it contradicts the latest available imagery, and claims to be sourced from older imagery

Make entirety of slip road to A1307 a trunk_link again

Cycleway under construction along Potton Road (northern end not visible in imagery)

This cycleway is permanently closed and partly demolished

Correct/add road name 'Potton Road' near St Ives

Whittington Heath Golf Club is building new holes to replace land that will be lost to HS2

Reinstate original sliproad to access A1307 WB

New A1307 slip road from M11 is not yet open; this reinstates the old layout (with fewer errors) and should be reverted once the new slip road opens

EB side of A14 J30 is now a roundabout; layout is approximate pending a site visit

Fix Citi 5 bus route following earlier changes to A14 slip roads

Dry Drayton EB exit sliproad is being relocated

Set construction=no on temporary piece of road near Swavesey

Add rough route of cycleways under construction between Dry Drayton and Swavesey

Fix highway types (link to A1307 isn't under motorway regulations yet) and improve aligment

Ref (A39) should not be part of name

Remove some demolished (or soon to be demolished) roads

A14 trunk is currently split between two carriageways past Bar Hill
