Netherlands has great motorways... I drove on the A2 between Utrecht and Amsterdan a few times in the last months... impressive.

Why couldn't they make the new motorway bridge where the temporary one is?

These are the other pics, it seems the temporary bridge is misaligned:





Also, it looks to me that the temporary bridge is lower than the old one, so building along its alignment may mean to rebuild all the embankments.

Why couldn't they make the new motorway bridge to the right of the old bridge?

EDIT;
Something like this:

red - old bridge to be demolished
yellow - new bridge

The new bridge will be constructed at the location of the old bridge, but with better geometry and lane width. There will also be an auxiliary lane westbound. The speed limit can go up from 70 to 100 km/h.

Replacing bridges on a different alignment increases the cost considerably, because the whole alignment of the motorway would need to be moved (which can result in S-curves). This also requires additional land acquisition. That's why they prefer to replace bridges at their existing location.

A59 has a large amount of on- and off-ramps. Some were eliminated / consolidated. The Waalwijk-East exit becomes a 30 km/h street. (Street View from August 2015!)

A1 Diemen - Muiden

Progress on the A1-A9 bridge across the Amsterdam-Rhine Canal near Diemen.

There are three bridges; the center one is for the reversible lanes.

The large arch bridge for the Amsterdam - Almere railroad. It will span the A1 near the Muiderberg motorway interchange.

Once they wrote about building a whole 'superbusway' (not sure how to translate it) between Diemen and Almere, how did that go?


I don't like bus lanes on highways.

It was part of the original plan (including the 14 lane Muiden Aquaduct) but was later scrapped, reducing the motorway cross-section to 12 through lanes.

The arch of the 255 meter long railroad bridge across the A1 near the Muiderberg interchange has been completed this weekend. The whole bridge will be moved to its final position over the wider A1 motorway by a SPMT. This will likely require a multi-day closure of the 200,000 vehicles per day motorway, as the surface need to be even (temporary pavement).

Do they need to close the railway too, or is the new bridge on a different alignment?

As far as I know they will slide the bridge into the position of the old bridge, likely requiring some kind of extended closure of the railroad. The Zwolle - Amsterdam railroad passes over A1 here.

Another rail component of the A1-A6-A9 widening is the A9 underpass under the six-track raiload east of Diemen. That was completed earlier this year.

The structure is already visible in Google Maps (which also finally got rid of labels - hurray!).



The new bases for the bridge can be seen underneath the railway, so we can presume the alignment will be kept.

The detail of the structure gives me two hypotheses: the thinner base will be used for another bridge parallel to the railway (maybe a minor road), or they may place the bridge right beside the old one and then slide it into position (with most rail works already done on it).
Plug&play...

Your second hypothese is right. They place the bridge south of the old bridge. There they will install all systems and the railway itself, before they slide it in position.

A12 Utrecht - Gouda

The speed limit on A12 between De Meern (near Utrecht) and Reeuwijk (near Gouda) will go up to 130 km/h, day and night, starting tomorrow. The other direction was already raised on 20 September.

They also converted the 'plus lane' (peak hour lane on the left side) into a permanent lane. This means there will be no more 100 km/h speed limits on this stretch.

It is the second 'plus lane' to open permanently, after the A4 plus lanes near Hoofddorp/Nieuw-Vennep opened to traffic permanently in 2013. There were also plus lanes on A2 and A67 around Eindhoven, but they were replaced by a complete reconstruction of the motorway.

Did they widen the plus lanes as well?

Yes they did.

That white narrow dotted line is until where the lane has been widened.

In my humble opinion, Netherlands has the best motorway network in Europe.

Made somewhat less impressive by the fact that the country has no B-road network worthy of the name.

What is the largest distance between two exits on the Dutch highway network? A country with so many exits does not need a B-road network.

The longest strecht without exits is A7 over afsluitdijk unless you count as exit the rest area
