That construction was long over due. Good that they finally started here.

They should create some kind of barrier switch for these situation.

The whole sidebar would have flexible end that would be able to move from left to right to form the side crash-barrier on left or right side according to what would be needed.

Something like this but automatic like the railway switch.

They should just apply the rule 'you break it, you bought it'.

It was a rare combination of closing the parallel highway of the A16 due to that truck and the barriers of the bridge in the A20 which malfunctioned for about 1 hour. Which blocked the northern part of the ring completely. The obstacles are removed but the traffic is still an absolute chaos on the ring and with a gridlock in the city.

Took me 50 minutes from Noordereiland to home in Schollevaar, which could be worse I guess, 5 mins more than public transport would have taken, and the weather isn't really nice for a motor or moped today.

The motorways are slowly moving, but the city is now worse than 90 minutes ago, complete gridlock .

What a mess!
I see roads that are otherwise never jammed all jammed up. Quite an exceptional evening rush hour.

N356 De Centrale As

The next phase of the Centrale As (provincial road N356) will open to traffic on 28 September. It is a 7.5 km segment between Dokkum and De Westereen, and includes the temporarily opened segment between Broeksterwâld and De Westereen.

It will open 3 months ahead of the already ambitious schedule. This segment was awarded in March 2014, so they built the four-lane expressway, including a fairly long bridge at De Falom, in only 18 months.

De Falom wildlife crossing during construction:

The minister of infrastructure has initiated the plan approval procedure for the widening of N33 between Zuidbroek and Appingedam.

* design environmental impact statement: early 2017
* final environmental impact statement: 2017
* construction start: 2018
* completion: 2020-2022

N35 Salland-Twente Tunnel, Nijverdal

The Salland-Twente Tunnel opened to traffic today after six years of construction. It is a 500 m long tunnel and 4 kilometer new alignment of the N35 through the town of Nijverdal.

This eliminates the last location in the Netherlands where a national road runs through a main street.

The tunnel is named for the regions it connects; Salland in the west and Twente in the east.

Miami Vice soundtrack...

Why did it took so long? The railway tunnel was opened years ago.

Also, did you say that the connection road on the west side, coming down from the hill, has a notable incline?

There is a climbing lane westbound, you can see it towards the end of the video. The old route also had a climbing lane, but this one is even a bit steeper.

The construction started in 2009 and was planned for completion in 2013. The railroad connection was suspended during construction, through train services were resumed on 1 April 2013 when the rail portion of the tunnel opened.

The reason why it was delayed was two-fold. First, there was a new tunnel law, and they decided to change the technical design, which lead to one year delay, with an opening planned for 11 December 2014. Then, there was a problem with the communication between the traffic control center (in Wolfheze near Arnhem) and the tunnel. They restored that in early 2015, but they still had to test all the systems, which was completed recently. So it opened with 2 years delay in all.

Curiously the railway tube has two uncovered sections:

Many projects in the Netherlands are very fast compared to some other countries (Germany and Switzerland in particular). This is partially due to the way projects are awarded, PPP projects usually have incentives to finish construction ahead of schedule without risking lower quality. In this case it is not a PPP project though, in fact it is rather traditional with many smaller contracts instead of one big package.

Another factor is the tendering procedure. Instead of focusing on price alone, they include other factors such as the construction schedule and traffic impact. This is a key reason why the Netherlands doesn't have many road works with long-term traffic impact like Germany. For instance the A12 widening west of Arnhem has only a few weeks of traffic impact in each direction. In Germany, a Baustelle for 2 - 3 years would not be uncommon for this type of project.

Awarding contracts is based on EMVI; economisch meest voordelige inschrijving, translated as the 'economically most valuable bid' which includes more factors than price alone. The environment, construction time, traffic impact and social factors are all included.
