routes – Austria (Villach to Klagenfurt) to Bled (Slovenia) without motorway

In December I plan to go to Bled while passing through Villach by car with my girlfriend.
I am really not motivated to pay Slovenian highways for a daily trip only and public transport from anywhere in Austria to Bled is a disaster.

Does anyone of you have experience on that fairly short route?
Most websites on the subject are very outdated and Slovenia continues to update individual streets and roundabouts from time to time.

So far, my plan is to go through the Wurzenpass and follow route 201 to Bled. (As Google Maps suggests)
As I failed a lot to get there a few years ago through Loiblpass, this time I want to be better prepared.

Is the suggested route free? Are there better ways than the curvy Wurzenpass (in December)?
And do you usually have suggestions or alternatives?

Driving – Highways of the United Kingdom motorway – Speed ​​limit

My TomTom Sat Nav tells you in a useful way the speed limit for the road you are driving, and even though you have a disclaimer that says you can not guarantee the accuracy of the update, I've noticed that all the motorways in the United Kingdom and double The access roads of the roadway and any interconnection route, whether single or double track, are indicated at 60 mph.

I thought that the speed limit for slip roads and interconnections of highways (eg, Highway that connects M3 with M27) ​​would be the same as the speed limit for the highway, which in the case of automobiles, motorcycles, vans derived from cars and dual purpose vehicles, is 70 mph (when you are not towing a trailer, another vehicle or caravan).

I have always believed that the Highway Code is the goal of driving laws within the United Kingdom, but the Speed ​​Limits page does not answer the question.

What is the situation in the United Kingdom?
