But you don't know if who calculated did a mistake. We should have the construction project.

It's clear that H1 standard is sufficient according to the guidelines. This is the case in virtually every country, as large scale implementation of H4a/H4b standard guardrails is far too expensive. I don't know of any country which uses H4-standard guardrails as their standard guardrail along motorways. But it's clear H1 (or H2/H3 for that matter), cannot withstand a truck.

In other words, accidents like this are considered acceptable, because they do not happen frequently and their impact is relatively minimal due to the low traffic volumes on most Spanish motorways. However, if this truck would have hit, say, a schoolbus with children, the politicians would scream why H4 standard wasn't implemented...

No one made ​​a mistake. I was working on certifying the proper installation of safety barriers. And if so, is in place.

OK. I see you have some knowledge in the matter and I have a question: wich type of barrier is this one, N2 or H1?

N2

H1 is only used to prevent more serious accidents than the invasion of a carriageway. Or, in medium conventional road with two carriageways. O in the separation of the main road of a service lane.

Luckily it didn't happen in the tunnel with liquefied gas.


Another point to take a look.

Last summer, Fomento made a test in several motorways painting signals on road as an aid to keep safety distance.

As we can see before the tunnel, this motorway was one of them.

Nobody noticed that the truck just went throught the only stretch without guardrail and that the broken guardrail was designed to stop impacts in the opposite direction?

Yes, and I don't think guard-rails are "bi-directional".

This guardrail can´t stop a camion. It is only design for light vehicles.

yes, i was just stating that the poor effectiveness that it could have on that kind of impacts was useless because the truck hit it in the rear.

But I think that with a guardrail on its carriageway maybe the truck wouldn't have got to the other carriageway.

About Guardrails, University of Zaragoza is working on improvement and has some advances.

Test are being done at Motorland Aragon, the circuit where the Moto GP of Aragon run in September (and this weekend, the first race of World series by Renault).

Take a look to news of today (April 30th, Aragon Noticias 1), in the minute 24:10

It is in Spanish but images and videos give an example about what they can do

I love Spanish motorways. One of my favourite countries to drive in.

Okey, so the most ridiculous motorway opening in the history of Spain has a new contender. This weekend a 7 km strech of A14 (Lleida) starting in the middle of nowhere and ending in the middle of nowhere, just opened. So ridiculous was this that no official opening ceremony was held. And this is an entirely new motorway built to replace the existing road N-240. The most bothering thing about this motorway is that it is absolutely useless untill it is properly connected to A2. The motorway strech can be seen in Google maps right next to the airport.

A picture from La Vanguardia

Here is the news in spanish from La Vanguardia, maybe some forumer here can translate it without using Google translate?

Lleida abre una autovía a ninguna parte

Fomento estrena por sorpresa un tramo de siete kilómetros de la A-14, entre Alguaire y Almenar, sin continuidad ni al norte ni al sur | Los alcaldes de la zona atravesada por la vía se enteraron de la apertura por una nota de prensa

Treinta y siete millones de euros para viajar... a ninguna parte. Es lo que ha costado la construcción del primer tramo de autovía (A-14), en la carretera que va de Lleida a Val d'Aran (N-230), estrenado por sorpresa este fin de semana. Son siete kilómetros de autovía que no ahorran tiempo al viajero ni conducen a ningún sitio. Y, además, para circular por la nueva vía desdoblada hay que recorrer 2,4 kilómetros, desde la N-230, a la altura de Alguaire, y otros dos kilómetros, cuando acaba el tramo de autovía, para llegar a Almenar y volver a conectar con la carretera de Val d'Aran. El estreno de ese tramo de autovía, que llega con un año de retraso según las previsiones del Ministerio de Fomento, ha sorprendido incluso a los alcaldes de los municipios atravesados por la nueva carretera, que no fueron informados de la apertura. Conocieron la noticia el sábado, cuando el Ministerio de Fomento lo anunció en un comunicado remitido a la Subdelegación del Gobierno en Lleida, del estreno de los 7 kilómetros de autovía.

La puesta en marcha de este tramo pone en evidencia, afirman habitantes de esos pueblos del Segrià, la falta de criterio de Fomento a la hora de planificar esta obra. Lo lógico habría sido empezar los trabajos con una conexión desde la autovía de Lleida-Barcelona, a la salida de la primera ciudad, y avanzar en dirección norte. Eso sí que habría ahorrado tiempo y riesgos a los conductores. Pero los responsables del anterior Gobierno optaron por iniciar las obras entre Rosselló y Almenar, lo que ha provocado ahora que el tramo estrenado no tenga continuidad ni en dirección a Vielha, ni en sentido a Lleida.

But that is fairly normal: an easier-to-build (and cheaper, probably dirty cheap in Spain with low construction costs) is completed before the more complex and challenging sectors of a highway.
