Per title I'll start us off with a nomintion for the section of the A82 along the north part of Loch Lomond side between Tarbet and Ardlui. This is the Glasgow to Fort William road.
Issues-
Too narrow to the point 2 HGVs or coaches have to stop and inch past eachother (this is an A road apparently)
Very very twisty (it follows the edge of the loch and historic horse and cart route)
Flooded permanently on west side of carriageway as cannot be easily drained given mountain and steep hill to west. Insufficient culverts / roadside ditches.
Very poor surface condition (given the lack of width, profile, drainage and permanent water on it)
Downright dangerous as very busy in summer with foreigners galore.
Shocking lack of improvement investment over the decades.
Stop start nature of driving it (when you know it and others dont) drives you a little mad.
Had the misfortune to drive it both directions yesterday, in this day and age just shouldn't be.
I'm sure there are hundreds of others. Name and shame.
I happened to drive this road a month ago when coming back from Oban. I haven't been along it for decades as we always take the Inveraray route going to and from Oban - but I thought - just for a wee change - see what it's like. After all - it can't be that different for the rebuilt stretch south end of the loch up to Tarbert. Wrong!
The stretch from Crianlarich to Arlui had me duped as we whizzed down that excellent stretch of road. And then we reached Ardlui. I actually could hardly believe the Ardlui to Tarbert stretch. Just as you have described - your first point being especially noticeable - an A Road when the traffic has to stop whilst wide or long vehicles manoeuvre past each other. Goodness knows what happens when two novice caravan pullers meet up.
