Red Army = most effective force !

The road range is problematic the moment you have to go off-road. Even more problematic the moment you have to fight, as that includes lots of dashes to the nearest cover, reversing etc.

Many roads, especially highways, have viaducts that can be easily blown up. Where off ramps from highways don't use viaducts they are usually on a some what elevated level. You don't have to drill through the tarmac if you can just go through the side through the packed earth. Highways are quick, but hard to get on and off, especially if the off-ramps are taken out. Units on it will be sitting ducks with very little cover or escape options.
Then there's for example the clever use of mines and booby traps to block routes around choke points, digging of deep trenches to block trucks, blowing up (high) buildings next to roads to block them, and then we're not even mentioning the use of nuclear demolitions or persistent chemical agents. Soviet AFV's may be protected from their nasty lingering effects, their trucks aren't.
There are so many ways to block the handful of vital roads from east germany into the west.
For me it wasn't until I started travelling between east and western europe in the early 90's and saw with my own eyes that I realised just how little infrastructure there really was connecting east and west. And not just across the border but also behind the border on the eastern side. Even without NATO harrassing them getting troops and supplies across the border would be a logistical nightmare.

how quickly could all this be carried out if an attack came as a suprise? on a random sunday morning in the 70s-80s.

soviet doctrine of combined arms offensive also calls for paratroopers to land in key areas, to hold roads, bridges etc. in addition to the forward elements Marcello brought up.

What surprise? If an attack was launched from the barracks many, maybe even most, WP units already in theatre wouldn't even reach the border on day 1, assuming that all units were combat ready. The limited access to the border again being a very big problem. A surprise attack like you suggest is usually a lot more disruptive for the attacker than it is for the defender.
Personally I do not think that the WP would have been able to pull off a suprise attack. If only for the simple reason that far too few of their units were with some consistency combat ready. Bringing a sufficient number to readiness is not something which goes unnoticed. It's quite a big deal. The WP simply was not capable of pulling off such a surprise attack.

And NATO defensive plans called for countless security units and defense in depth, not to mention an extensive anti-aircraft screen to counter the well-known soviet doctrine. Again, a massive paratroop and airlanding operation is not something you can just pull out of a hat. It takes a lot of preparation. It is not compatible with the concept of a surpise attack. Either yo have a suprise attack, which means few forces available to begin with and nowhere near enough for serious paratype operations or you take your time to preapre in which case a surprise attack is no longer in the cards. Can't have it both ways.
Your scenario does read well and quite a few novels have been written around that idea, but I find it far fetched and unrealistic. It too ignores the massive logistic preparation needed BEFORE you can even contemplate launching an attack. That is not something which would have gone unnoticed (and which takes weeks at least, probably longer).

The whole assumption that the WP could pull off a quick surprise attack with anywhere near the troops needed for success and get them there on time is in my opinion inherently flawed.

There were for example about four major roads between Czechoslovakia and West Germany. By the 1980's moreover the borders were subject to patrols of SLAR equipped aircrafts - hard to hide tank columns from them.

"Drains, covered sewer entrances and culverts can be packed with explosives to disrupt paved surfaces if you don't have time to pierce the surface."

Sewer entrances are available only inside cities. Culverts and such will not be conveniently sited in the best places for demolition. You need to plan in advance for identifying the locations and which demolition team must go where, they must be reasonably accessible in order to emplace charges (not filled with water or too small to enter etc.) and when all it is said and done it will be a limited damage that engineers can repair quickly. I have no idea if it was even taken in consideration.

"There was also the debate that certain NATO forces had stockpiles of arms that would have been released to the German population in major cities, arming hundreds of thousands of civilians."

It sounds pretty useless to me.Most of the people will either be fleeing towards NATO lines (from what I have heard, NATO planners considered it a big problem, as they would have created traffic problems for NATO columns plus those civilians had to be fed and sheltered putting further strains on logistics), hunkering down or otherwise too shocked to mount anything resembling a guerrilla campaign in the first few days when it will matter most.

"You don't have to drill through the tarmac if you can just go through the side through the packed earth. Highways are quick, but hard to get on and off, especially if the off-ramps are taken out. Units on it will be sitting ducks with very little cover or escape options."

There are others places that highways can be entered or left, especially for the combat vehicles. Service areas may have connections with the road network, there are often dirt roads within reach of highway in cultivated areas etc.. This quite beside the fact that taking out a significant numbers of off-ramps is quite a lot of work.
It is not like drilling thought the tarmac is the only problem. Even in the earth you still need to dig a lot of deep holes, or otherwise the damage will not be sufficient.The practical experience with bombing runways that I am aware of has shown that paved surfaces are more difficult to damage and quicker to repair than many (included myself before I found out) imagine.

"digging of deep trenches to block trucks"

If you have ever seen digging trenches in paved roads, you would realize that is not very practical.

"blowing up (high) buildings next to roads"

Outside urban centers that would be a pretty rare option.

"and then we're not even mentioning the use of nuclear demolitions or persistent chemical agents"

Nukes, well you are opening the pandora box. Using chemical weapons would be the best Christmas present you could give to the soviets. You can then sit back and enjoy the show of soviet chemical warheads missiles falling on NATO airbases,with the effect of massively cutting down NATO air forces sortie rate. This was a substantial concern for NATO planners back in the days.

"The road range is problematic the moment you have to go off-road. Even more problematic the moment you have to fight, as that includes lots of dashes to the nearest cover, reversing etc"

I got the impression that when the soviets specified design ranges for their vehicles, they did so with certain key objectives in mind. Yes, those 600 something km might be cut down to 400 something practice but I think this was aknowledged. If anybody has a map with NATO airbases at hand I think we might find something interesting.

[Marcello]

I also doubt that a surprise attack was feasible. A short notice attack was probably all they could hope for even under the best circumstances.

Tell that to British XXX. corps veterans from op Market-Garden And also the argument isn't it would stop combat troops. But what would mechanised spearheads do wtihout fuel and ammo? Plus of course any traffic jam among supply vehicles caused by road disruptions would be a very juicy target for NATO aircrafts. Let's spray the jam with cluster bombs and Gators...

VT-55 recovery tank has a road range of 270km, off-rorad range 100km in straight line (and it has lower consumption than basic T-55 as it is lighter).
In combat, I'd expect the fuel last for 200-300 kilometers in T-55 with fuel drums and a road range of 600km. If you take into account the combat consists not only from movements forward, but also sideways and back, it would cut down the real range of penetration into NATO lines further. And the advance would slow down again when field commanders find out the number of supply trucks coming to them is so low.

If you reread my post you'll see I said digging deep trenches (easily done even with commercial diggers) to block trucks driving around blocked roads not in order to block the roads. So that'd be next to roads and in fields, not the roads themselves. Also a good and very quick way to make those exit points a lot harder to make work.

Marcello said:

But since there are plenty of those not rare at all. The large number of roads and urban centres are being used as advantages to the WP so also take into account the drawbacks. Devastated towns are hard to advance through.

On the whole your argument seems to be that it would be hard for NATO to demolish things effectively while it would be fairly easy for the WP forces to overcome them. I think you've got it the wrong way around. It is much, much easier to demolish and block than it is to clear and circumvent.
It's also being stated that the WP had prepared and developed for this, etc. Well so did NATO, the germans in particular.

Another point is the opening of hostilities itself, the assumption is, I assume, that firing will be initiated by the WP with the comencement of the cross border attack and/or preparatory artillery strikes. I doubt it would happen that way. The war would be on before any troops crossed the border. NATO wasn't stupid and would know full well what the massing of WP troops near the border would mean. Stern warnings and ultimatums would be given. When those were not met, (conventional) cruise missile and air strikes on the forces in east germany were extremely likely. I won't sepculate ont he results of those, the point is that in my opinion there would likely already be a shooting war before any WP ground forces crossed into NATO terrirtory. That would make the intial attack much harder still.
