There's no problem with open sections of the road, since there's nothing which could collapse in case of a strong earthquake. On the other hand, tunnels and bridges (and viaducts) could be impacted, but they are strong enough to withstand it. There have been many earthquakes in the last 50 years, but no road object was ever damaged. There could only be a problem with earthquakes followed by landslides in the Zagorje region (especially on A2 motorway).

i think that A4 is more liable to landslides than A2.

Tunnels are already naturally more safe from earthquakes than viaducts.
As for viaducts they are sure pretty safe from ordinary earthquakes, but really strong earthquakes (that happen every 500 years - this however can mean already today) could be very damaged.
I don't know the situation for Croatia, but the most complicated and largest viaducts in Slovenia are build with special dampers. This is also true for viaducts on Italian A23 in Valcanale. Why only the largest? It is to prevent irreparable damage even for strongest earthquakes possible as they are capital investments and their repair could take two or three years, smaller viaducts can be repaired or rebuilt in half a year or in one year.

Actually, the road on the pictures above is not A1 (motorway), but D425 expressway connecting the town and harbour Ploče to the motorway A1. All which is finished (parts you can drive on) is already opened for traffic, while there's another 6 km of the expressway and about 10 km of A1 to be done.

You can see on a map: http://wikimapia.org/#lat=43.1452741...1&z=12&l=0&m=o
blue dotted line: not-finished part of A1 (Vrgorac-Ploče)
green dotted line: u/c part of D425 from Ploče exit to the finished section of D425

Our prime minister said that these routes are the most important in road investment program, so it could be done somewhere in 2013...

Works on the new exit (Anđeli) on B8 expressway (this section would not become A8 like the first part, because A8 will go from Učka tunnel to the north and new junction with A7)

Nice work!
To screw up about two hundred meters visible part for overpassing on this mostly unoverpassable road whom only overoptimists call "semiexpressway", and what for? For a complete unnecessary interchange, which only purpose will be to overcongest even congested road with local traffic!
Really nice work indeed!

Oh I forgot. Sure the village Anđeli is a hometown of some prominent member of new Croatian socialist government.

Why they didn't convert TRAFFIC LIGHTS on the "interchange" Opatija into a REAL interchange instead of?

I think they will solve it when A8 will became a motorway. Does the traffic volume justify the 2nd tube of Ucka tunnel?

Well, the decision to make that new exit was made during the previuos government (HDZ), so don't say such things if you don't know the exact story

On the other hand, it's true that this part is very dangerous and traffic runs slowly, but there were many illegal "exits" because of the tough terrain and lack of other local roads. But that part won't become A8, but will stay as an ordinary grade-separated state road which will go from A8 to Rijeka...

True, the future A8 will go to the north from this point, where a junction will be made to turn to that today's part of the road: http://wikimapia.org/#lat=45.3297028...9&z=14&l=0&m=h

The AADT in Učka tunnel is 7670 vehicles, but during the summer it's 11 087 vehicles. In normal circumstances one tube would be enough, but that's a 5-km-long tunnel and must have 2 tubes according to the european regulations. An emergency tube doesn't make sense, because that's a motorway and the traffic volume will be increasing all the time, so it's better to build the normal second traffic tube

Okay, my only mistake was erratically identifying SDP instead of HDZ. Even you should know that Sanader ordered building of a complete unnecessary exit on the Dalmatina motorway.
But no more sarcasms.
At the beginning I shall quote some axioms of traffic science.
1.) Local and transit traffic must be separated.
2.) Road which is called an expressway shall not have exits or interchanges regulated with traffic lights.
3.) Road must be safe for driving.
Ad. 1. Drivers who drive on this road, which is eastern connector to the Učka Tunnel, already pay the toll for it, included in Tunnel Učka toll. So they have absolutely right to be excluded from local traffic for this toll. Instead of that Bouygues prized local imbusters (who already imbusted a dozen or more wild exits) with legal, but completely unnecessary exit. What will happen? There will be even more local folks with their small cars, who will regularily have speed limit about 50-60 km/h. Does this have sense, I mean from the safety point of view?
Ad. 2. I have discussed the problem of traffic lights on the Opatija "exit" several times before on this thread. So I won't repeat myself. But, this secretly tolled connector common road with some expresswaymanner exits shall not be called even semiexpressway. And if Bouygues wanted to improve the trafic conditions on this road, they had to upgrade Opatija "exit" to the real expw exit at the first place.

Well, that exit (Vučevica) would serve Kaštela, city with 38 500 inhabitants, when the expressway is built. Also, it would be very good alternative for Split too, because people would no more have to go to Dugopolje and via D1 if they want to go to western part of Split (a bridge from Kaštela to Split is planned too)

I totally agree with you. Motorways should be spared from many and densely located local exits, but you shouldn't treat that part of B8 as a motorway or a true expressway, because it was built as a normal highway (magistrala) back then in the 1980. Later they decided to include it into motorway system.

In the end, Bouygues is just the contractor, while the concessionaire is the Bina Istra company, which follows the commands from croatian ministry of transport. So, Anđeli exit is being built because Croatia (and Primorsko-goranska county) wanted it.

Opatija traffic light is nonsense, but there was a plan to upgrade the exit to the normal grade-separated exit, but now I can't find that photo I don't know why it was never built; probably because spatial plans of local communities and a county weren't in compliance.
It was something like this:



EDIT: I found that plan:

Fortunately, in the year 2018 Učka Tunnel shall have second tube for the safety reasons, to be compliant with European Regulative. So they will be forced to build not only missing northern tube but also a completely new motorway from A7 to eastern portal of the tunnel.
Till then, I will avoid B8.

The deadline for the second tube is 2015 We'll see when will the new section (Učka-Jušići) be finished...

No news. Situation is as before, so nothing is to expect in next 5 years.
