Yes it is. It may require deeper portals and hence deeper and wider cuttings
at either end...
The present proposals for a new additional roundabout at Longbarrow Cross
south of the existing one will also cause some extra disruption. It isn't
clear yet whether there will be a cutting on the approach to this too. There
will also need to be a route provided for those who can't use the tunnel
(pedestrians, cyclists and horse-riders) alongside the dualled above ground
bit between Longbarrow Cross and the western tunnel portal. Other traffic
which can't use the tunnel is likely to be sent on a detour along the A36,
Packway and back down via Durrington Walls to Countess roundabout.
Unfortunately since this is to be built under a design and build contract it
isn't certain that any of this will turn out to be exactly what is
There are also a number of issues yet to be resolved about interactions
between people using the north/south and east/west byway/bridleway routes
and what they'll do when they see the Stones. My bet is that they'll head
straight for them and not follow the neat routes currently shown on the
plans. There's some potential for erosion along desire lines.
