the old carriageways, then an overnight closure for the final switch

made. The same procedure would then be followed a few months later to
divert the southbound carriageway to the new alignment.

The amount of work you would be expecting them to do "overnight"
beggars
belief.

I disagree.

Build the two new carriageways. At each end, cut them off very close to
the edge of northbound lane 1 (there's no hard shoulder, right? if
there
is, adjust description accordingly).

Cone off northbound lane 1. Spend a week or two filling in the narrow
gap between the old and new northbounds at each end.

Not sure that you even need a closure to switch over. Simply move all
the cones.

Repeat for the southbound (though this time you're closing lane 4).


Yes, that's what I'm expecting.

I have never in my life seen construction companies do this

even when the new road is well away from the old route

It costs millions extra to do it that way

Why would it cost any extra?

because you have to build a "throw away" access road to the new build road.

I take it you've never looked at a map of the area, or even Google Maps?


The alternative of accessing via the current road is "free" but causes some
of that road to need closing

There are plenty of other existing roads, including the A4, they can use
for access to the work sites.
