Highest dual carriageway?

[anonymous-user]

It's fairly common knowledge that the M62 has the highest point on a UK motorway. What I find harder to Google is the highest point on a dual carriageway.

Is there anywhere on a dual carriageway higher than that point on the M62?

Heads of the Valley in S Wales I think is higher. (A465)

410 metres according to Wiki. Is there anything in Scotland higher than that I wonder? Maybe on the A9 where dualling is in progress?

There's a bit of dual carriage way at Slochd Summit which is between 400 & 410metres, but I can't find any info about the actual carriageway elevation.

These's also a bit of DC just south of Dalnaspidal Lodge which goes above the 450m contour, again no spot height.

It looks to be about that. But it's not dual carriageway there.

According to my OS map, the highest point of the DC is 451m at the top of the Drumochter section of the A9.

A66 at Bowes Moor is 441m (1450ft) at Stainmore Summit.
