N31 Harlingen Aquaduct

The Council of State has rejected all appeals against the widening of N31 and construction of the aquaduct.

The crossing with the Van Harinxma shipping canal will be an aquaduct, where the N31 will run at -10.0 meters. The whole depressed route is 1.8 kilometers long. This is the final project to widen N31 to a motorway or a 2x2, limited access expressway. Construction is expected to begin in 2013. The project is due for completion in 2017 and cost € 143 million.

Will it remain a national route or be upgraded to motorway?

It will remain N31, with a speed limit of 100 km/h and expressway status. The N31 was previously upgraded south of there from Zurich to Harlingen, but also retained N-status.

A15/A50 Valburg interchange

The Valburg interchange will feature two turbine connectors starting Friday 8 February at 5 a.m. These connectors replace two cloverleaf connectors. It is part of the widening of A50 to 2x4 lanes. This means one less cloverleaf in the Netherlands, and one more cloverturbine. The number of standard cloverleafs has been declining in the Netherlands in the past 5 years. There are currently more cloverturbine interchanges than standard cloverleafs.

I really thought they were going to turn it into a motorway all the way to Leeuwarden.

Surprised Rotterdam - Apeldoorn direction doesn't get a turbine connector. Lots of trucks taking that route.

I'm guessing they expect trucks to continue straight ahead if they build the A15 extention!

That's right. Most of them will carry on towards Germany, and not so much the north east of the Netherlands.

I'd imagine most will use the A15>A27/A28 if they need to go to the north, much shorter route! ( assuming truck traffic from R'dam, or even the A12)

You're right, I forgot about that. Hopefully toll won't be too high so that it is actually profitable for trucks to use that route.

2012 traffic statistics

Rijkswaterstaat published the third road network performance report of 2012.

The number of kilometers traveled in 2012 was down by 0.1% compared to 2011. 64.7 billion kilometers were traveled on the national road network (chiefly motorways).

The number of traveled kilometers during rush hour increased nonetheless, the 0.1% overall decline came from the low periods. This is likely a result of the road widenings, as fewer people need to avoid the long rush hours that previously existed.

The annual traffic jam weight (minutes * kilometers) was down by 16% in 2012, down from 10.5 million kilometer minutes in 2011 to 8.8 million kilometer minutes in 2011.

The amount of traffic jams as a result of road works is 5.5% or 480.000 kilometer minutes. This is slightly more than in 2011, when it was 5.1%.

46.1 million hours of vehicle delay was recorded on the national road network in 2012, down by 14.4% compared to 2011.

Average trip reliability was up by 1% in 2012, to 93% of all trips. This also includes trips with delays, but reliable delays (most days have the same delay).

Shoulder running proved to be an improvement of traffic safety. Fewer accidents occurred when the shoulders are used as driving lanes, due to less congestion.

77% of traffic congestion is a result of a lack of roadway capacity. 14% is the result of traffic accidents and the remainder is due to weather or roadworks.

The index graph of traffic congestion and road mileage development. Interestingly the little spike in 2010 occurred when mileage was actually a bit down, while the largest traffic increase corresponded with the biggest decline in traffic congestion.


The top 10 worst congestion spots in 2012:

1) A50 SB at Ewijk interchange - 268.237 kmmin
2) A20 EB at Terbregseplein interchange - 252.164 kmmin
3) A9 SB at Raasdorp interchange - 181.393 kmmin
4) A10 NB at Coen Tunnel - 173.498 kmmin
5) A15 EB at Vaanplein interchange - 170.644 kmmin
6) A13 SB at Kleinpolderplein interchange - 150.629 kmmin
7) A16 NB at Terbregseplein interchange - 127.855 kmmin
8) A4 NB at Zoeterwoude-Dorp - 122.343 kmmin
9) A27 NB at Bilthoven - 119.001 kmmin
10) A1 EB at Soest - 117.268 kmmin

1, 3, 4, 5, 8, 9 and 10 should all be gone within the next few years. Its especially the Rotterdam area that deserves some upgrades, but it won't be easy because most highways run through dense build up areas and there's not much room for alternatives.

Nice video. Are you sure the bridge construction has cost only € 40 million? The Waal Bridge at Ewijk has similar dimensions and costs about € 200 million. Of course there is 15 years of inflation, but it's still a large difference.

N50 Ramspol Bridge

The Ramspol Bridge has been in full operation for nearly 2 months now. I paid a visit to the bridge today, photographing the old bridge before it's being demolished.

The old bridge, opened in 1948, is now permanently open to shipping.

Nice views from the new bridge. The tower on the left is a tower from the early Cold War with guards watching the horizon for low-flying Soviet airplanes. It was an early warning system.

The southern span was a steel girder bridge.

A few kilometers to the south is the site of the Island Bridge, opened in 2003, part of the same road.

The old bridge is structurally obsolete and in poor condition, as this photo shows.

I still haven't noticed the decline and won't for the next few years. The A9 Haarlem/Badhoeverdorp is a pain in the ass and won't be fixed for years.

Well, not all bottle-necks will be dealt with as quickly as we want it. Especially the Rotterdam Area still will face heavy congestions on the A20 (Terbregseplein-Gouda and vice versa) and on the A15 (Ridderkerk-Gorinchem and Gorichem-Ridderkerk). Especially the A20 will soon become the number 1 bottleneck in The Netherlands network of highways. And the A13 will only get relieve from the A4-MD (Delft-Schiedam/Vlaardingen) as of the end of 2015. So there will be many traffic jams on that stretch as well for the next almost 3 years to come.

That is correct in my opinion.

The difference is whether your corridor has been widened or not. For example a commute on southbound A9 will not make much difference compared to a few years back, but people on A12 or A28 will have free-flow traffic at rush hour, entirely eliminating any delays that happened previously on those stretches.

Purely aesthetic reasons surely ? Has no advantage over 2 viaducts ??


Also, why are there traffic lights on the road going up when it's only for the couple of buildings located there ? Surely raffic is WAY to small to justify traffic lights ?
