A6 Ketelbrug

The Ketel Bridge in Flevoland. The A6 motorway runs across it. It opened to traffic in 1970, at a cost of 24 million Guilders. It's 800 meters long and the clearance is 12.70 meters. There is a bascule section on the left (south side). It carries 45.000 vehicles per day. It malfunctioned a couple of times in recent years, though no replacement is planned. There are some wild ideas about a tunnel but I don't think they can ever find funding for that (and rightly so).

It's not just a road improvement project, but also a large urban renewal project, with loads of structurally deficient housing being demolished and replaced by new housing.

1. Interchange Europaplein, looking from the south.


2. Tunnel excavation


3. the northern entrance at "De Geusselt", some of you may know it because of the football stadium and McDonald's located there.
How long will it be (excluding ramps)?

The enclosed section is 2.6 kilometers long. The entire project is 4.9 km long. The project cost is estimated at € 700 million (including urban renewal).

€ 700 million is not so bad, considering the scale of the project. How is it financed?

Straight from the national government's coffers, as are the vast majority of freeway projects. They may have put up some stuff in DBFM contracts but that's just another payment strategy.

€ 565 million is financed by the national government, € 144 million is regionally financed.

True, I forgot that. Then again we're talking about national taxes that get distributed to the provincial level where they can invest in whatever they see fit.

I just hope with the next austerity package looming there isn't going to be a big change in the forward looking policy we've seen the last couple of years.

A4 Halsteren - Dinteloord video update

Riding on the new A4 between the Zuidzeedijk and Dinteloord (1 km, after that I had to stop: last exit of the new A4) (no asphalt yet)


Near exit Dinteloord:

A2 tunnel at Leidsche Rijn, Utrecht

This tunnel is meant to reduce noise and exhaust fumes and also to abolish the barrier caused by A2 between Utrecht and Leidsche Rijn (new city extension).
One direction (North-South) has been put in use ca. two weeks ago. The other direction is still awaiting completion of the safety/security systems.
'Today I had the opportunity to pass through it.








The old motorway half is now out of order:

A4 Halsteren - Dinteloord picture update

Click here for all 140(!) pics (including locations)

A new road was being connected to the A4/N259/N286 intersection just north of Halsteren. This road goes over the viaduct of the A4 at Halsteren. This is at 13:00


Situation at 16:30. I wonder if they're going to move the stop line backwards.


Some activity at the viaduct of exit Halsteren:


The private road near Klutsdorp has been removed. Now they can really start working on the A4 near Klutsdorp


There were also some roadworks on the cycling path of the N259. Situation around 16:30


Former Nuijten farm. you can already see the 2 different directions! Middle = towards Rotterdam, right = towards Bergen Op Zoom


Piling rig at the Steenbergen aqueduct


N259 just north of Steenbergen. Location where the A4 will cross the N259. The N259 will go over the A4. This is the spot between the slopes where the A4 will go through.


Piling rig Zuidzeedijk:


Dinteloord viaduct:


(Attempt of) an overall picture near exit Dinteloord:


A29 near Dinteloord. Because of the light there's a weird clolor which makes the pic a little bit more beautiful (imo)

Old bridges

The Netherlands had many bridges which used to be in operation with 4 lanes, but were later replaced by more modern bridges or tunnels. Virtually all of these bridges have been reduced in lanes.

Bridge across the Noord River near Alblasserdam (Zuid-Holland province). The photo was taken in 1970. The bridge used to carry the trunk road 15 (currently trunk road 915) and was replaced by a motorway tunnel with 2x3 lanes in 1992.

source: https://beeldbank.rws.nl, Rijkswaterstaat / Afdeling Multimedia Rijkswaterstaat

Notice the 4 undivided lanes. Many of these bridges had very narrow lanes, often not more than 2.80 m each. The only major bridge still in the 1x4 configuration is the Waal Bridge at Nijmegen. Most of the bridges with this former configuration were constructed in the 1930's.

It wasn't until the 1930's that many river crossings were bridges instead of ferries. Only rail bridges are usually considerably older, dating back to the 1870's. Some bridges in the Rotterdam area were older, dating back the the early 1900's, but none of them still stand today, they're replaced by new bridges or tunnels. Many of these had virtually no clearance and were swing bridges. There are still a few swing bridges around, none of them in major roads.

Have been working and studying for quite a bit in the last weeks (sigh, an exam again tomorrow), but last week I was able to make the next video of the Dutch highway A12 near Utrecht. The western part is quite neatly, but after passing Utrecht the traffic jam starts because they are still working the expand the road.

Some more information can be found on my weblog.

Moerdijk Bridge history

The Moerdijk Bridge has some interesting history.

The first bridge to span the Hollands Diep River was a railway bridge, which opened in 1871. However, it was still 65 years away before a road bridge opened. The Hollands Diep is the widest river in the Netherlands, the width varies between 1 and 3 kilometers. It is also the border between Zuid-Holland and Noord-Brabant provinces.

The first road bridge opened to traffic in 1936. It was one of the longest road bridges in Europe at the time, spanning just over 1 kilometer. It was a truss bridge, which was a relatively uncommon design in the Netherlands in the 1930's, as most bridges were constructed as steel arch bridges.

The bridge was bombed in 1944 by the retreating German army, and restored in 1945 with portions of the railway bridge. A more definitive repair occurred in 1946. This bridge had the highest priority in the Netherlands due to its importance for north-south traffic.

Traffic counts in 1950 recorded an average traffic of 5.200 vehicles per day. This raised to 12.430 in 1960 and 30.650 vehicles in 1970, and it became clear the old bridge needed replacement. The original Moerdijk Bridge had an 11 meter wide carriageway with 4 narrow lanes of 2.80 m wide.

The replacement progress was particularly challenging, mainly due to novel techniques used. They considered a cable-stayed bridge with a 400 meter span for a time, but it was considered too expensive and too much of an intrusion on the landscape horizon. So they decided to use the existing 1936 bridge piers. The main problem though, was that the bridge needed to be nearly 4 times wider, but could not be heavier. They replaced the concrete deck with a steel deck, allowing for 6 lanes, 2 shoulders and 2 slow traffic lanes (provision for 2x4 lanes with shoulders if an alternative bridge is constructed for slow traffic).

A problem though, was that the steel deck was 1.6 meters thicker than the concrete deck, and the bridge could not be taken out of traffic for 2 years during its replacement, so they jacked the bridge up by 1.6 meters to match the height of the future steel decks. After that, the 10 spans were replaced span by span during weekends. The replacement of the bridge was completed in 1978. The existing spans were still in good condition, and were re-used elsewhere. Six spans went to the nearby Keizersveer Bridge (A27 motorway) and four spans went to the replacement of the Spijkenisse Bridge (N492).

Moerdijk Bridge in 1936:




Moerdijk Bridge in 2007:


Note there is a single part of the original 1936 truss as a monument on the side of the road.
