If you count the hard shoulder as a lane, the Dutch A4 near Schiphol has several stretches of 2x6 with hardshoulder, and the A2 Holendrecht-Maarssen consists of 2x5 with 4 hard shoulders, of which the inner hard shoulders are of double width.

Dutch A4 south of Hoofddorp is in reconstruction now.
When completed, it will have a S2(C)-S5(E)-5S(E)-2S(C) setup over a length of about 4 km. 7 lanes for driving and 2 hard shoulders in each direction.

(S=shoulder, E=express, C=collector)

A15 Rotterdam

The first phase of the A15 widening project along the southern side of Rotterdam will be completed this weekend. All lanes will open Sunday morning.

The newly widened stretch is located between the Benelux interchange (A4) and Vaanplein interchange (A29). A local-express system was constructed here. The through capacity between the two interchanges is 10 lanes, with 12-14 lanes at the widest segments.

Construction took 2 years and 2 months.

I drove from Vaanplein to Benelux a couple of weeks ago. I drove on the new parallel westbound carriageway between the 2 interchanges.

Now to finish the A4, hopefully some traffic will avoid the A16/A20/A13 route and traffic coming from the south will use the new route to The Hague or Amsterdam.

Unfortunately, until an A16>A13 link will come though I think the A20 will still be congested .

A50 Ewijk Waal River Bridge

The Waal River Bridge is being renovated while traffic is being detoured via the new bridge.

They will replace the cable stays, which is quite a unique process that has not been done this way in Europe before. Although cables have been replaced in Europe before, the Ewijk Bridge has only two pylons with 4 cables, 2 sets of 2 cables at each pylon. They run across a saddle in the pylon.

To replace the cables, the saddle will be lowered, allowing the cables to be replaced, 2 at the time. The bridge has two pylons, so when the cables are being replaced, the amount of cables attached to the bridge deck is reduced by 25% (2 out of 8 cables).

The difference with most other cable-stayed bridge is that other bridges tend to have many more cables than this bridge, so they can replaced easier without reducing the carrying capacity too much. The bridge is entirely taken out of traffic, so there is no live traffic load.

The large cables (highest) are 221 m long and have a diameter of 37.5 cm. The smaller cables (lowest) are 135 m long and have a diameter of 33.5 cm.

Replacing the cables will take about 9 months and will begin in early 2014.

N340 Zwolle - Ommen

The coalition in the province of Overijssel has disagreed at the very last moment about the N340 upgrade project. Coalition party VVD voted for a motion to reduce the budget by circa € 150 million, making the "shovel ready" plan unfeasible in its current form.

Parties had different motives to vote for the motion, the Greens and left-wing parties found the road upgrade unnecessary while VVD (liberals) wanted to upgrade N35 instead.

A few notes;

* N35 is a national road, Overijssel province has no authority over it
* N340 is a provincial road.
* the project is shovel ready, all procedures have been completed and land acquisition has already begun.
* N35 upgrade is years away, even with accelerated funding from the province

I do agree that N35 should have a higher priority to upgrade, because it carries more traffic, is more congested, less safe, and carries more long-distance traffic with no good alternatives. N340 is not very problematic and traffic growth is minimal. However, I don't think it's good public governance to withdraw funding this late in the process. They should have made up their minds a few years ago. Right now we won't see any major upgrades because there are absolutely no detailed plans to upgrade N35 beyond the Wijthmen bypass.

Hopefully this drama will open the door to a quick twinning of N35 between Zwolle and Raalte. Because that is not on the table yet, but highly desired. N35 is the main backbone of Overijssel province and serves 4 out of the 5 largest cities.

There is still work to do on the Westbound stretch between Interchange/Knooppunt Ridderster and the Interchange/Knooppunt Benelux.

Two viaducts are still being constructed for the most northern parallel lanes. When finished traffic coming from the A15-A16 section driving toward Rotterdam & the Ports can not use the main 3-lane fly-over towards the A15-Westbound if they want to continue to the A29 in the direction of Zierikzee and Roosendaal (and Barendrecht-Carnisselande).

They will need to use the former main route (with the right and left turns in them) to access the parallel lanes. This needs to be done at the Interchange/Knooppunt Ridderster because after you have passed that there is no possibility left to leave the center lanes going to the Ports and the Beneluxtunnel via the Interchange/Knooppunt Beneluxplein.

I suspect it will take certain drivers who do not visit this area frequently quite a while to get used to that change.

A4, Hoofddorp interchanges

The new A4 interchanges at Hoofddorp opened to traffic today. It also includes a short local-express system, which means the A4 has been widened to 14 lanes at this location.

N201 Schiphol Airport

A new stretch of 4-lane N201 also opened to traffic today, from A4 to the Melbourneweg. It features a new viaduct across the old N201 (now N196).

Interestingly, a 900 meter segment of 2x2 N201 was built in only 8 months. They didn't acquire the right-of-way until 26 April 2013, and it opened today, 15 December 2013. The foundation was piled to skip the settlement period.

They were behind on the original schedule due to juridical hassle over the right-of-way (the ground) on that specific 900 meter stretch.

A4 Hoofddorp

A few photos of the new local lanes of A4 at Hoofddorp.

Northbound:

As you can see the cross-section is 16 lanes between Hoofddorp and Hoofddorp-Zuid, but the outer lanes are auxiliary lanes between the two interchanges. 14 lanes are through lanes, eventually merging into 10 lanes. However, it has been proposed to extend the local lanes to the N207 at Nieuw-Vennep.

N50 Ens - Emmeloord

Transportation minister Schultz signed the draft EIS for the widening of N50 between Ens and Emmeloord.

The existing road is a super two with shoulders, so additional right-of-way acquisition is not necessary. The widening costs only around € 17 million and will be completed in early 2016.

What about upgrading from the A6 junction towards Kampen? Perhaps get rid of those traffic lights to begin with...
