Still somewhat OT, but rural Norway has plenty 5 m wide (and narrower) roads. Acceptable if traffic is light and without HGWs, but that's it. New national and county roads vary considerably in width depending on expected AADT, 6.5, 7.5, 8.5 and 10 m are all standard 2-lane profiles - 0.5+2.75+2.75+0.5 for the narrowest, 1+3.5+1+3.5+1 for the widest.

I would guess that it's temporary to discourage taking over!

There is a trend to use less yellow markings for workzone situations that exist for a longer period of time. Yellow markings are used for workzones where the situation requires more attention or where the road layout changes frequently. In this case the lanes are slightly narrower but otherwise have little impact on traffic.

Much of the eastbound widening was done without additional congestion. The speed limit was slightly lower with 90 km/h, but 3 lanes were always available during the day.

I really like how roadworks are done in the Netherlands. Short and heavy is the key. Better have a few night / weekend closures than months of congestion with switched lanes.

For example they repaved A4 around Delft in both directions and replaced bridge expansion joints during just 4 weekend closures. Long-term roadworks have rarely a lower limit than 90 km/h these days. Much is done to reduce the impact of roadworks on traffic flow.

They do the same in France. Although the A5 widenings south of Troyes dragged on a bit.

A10, Amsterdam

The first part of A10 has been repaved to its final situation. From S112 to A1. The segment from A2 to S112 will be repaved next weekend.

How many asphalt pavers were they using? I see too many trucks unloading at the same time.

I think they were using too many pavers in that tight space. Why not using pavers with extensions so that they use fewer?

Do you have more pics?

I guess the more equipment, the faster they get the job done. I'm sure they know what they're doing...

I can't tell for sure, but I think they are more flexible with small pavers which can be transported quickly. I suppose large (carriageway-wide) pavers need assembly on-site, which is not something you can do during just a weekend closure. I even doubt if they have pavers that wide in the Netherlands, because entirely new motorways are rare.

Indeed, the "standard" pavers can be transported quickly by a normal trailer, but if you want to use it with a larger width you can add extensions. The assembly/dissasembly takes about 2 hours, but it increases the efficency. You can see here a paver in Romania with the extensions mounted (the extensions width can vary):

It may also be easier to transport so many truckloads of asphalt in such a short duration to 6 small pavers than to 1 big paver.

A1 Apeldoorn - Hengelo

Gelderland and Overijssel provinces have proposed to provide a loan to the national government to widen the A1 motorway from Apeldoorn to Hengelo. The widening project has been postponed a couple of times due to budget cuts, and no final variant has been chosen yet.

A regular widening to 2x4 and 2x3 lanes is the cheapest at € 450 million, a parallel system between Apeldoorn and Deventer is the most expensive at € 980 million because two parallel bridges would have to be constructed across the IJssel River.

The provinces hope to begin construction in 2016 or 2017. The segment to be widened is 48 kilometers long, and will likely get 8 lanes from Apeldoorn to Deventer and 6 lanes from Deventer to the Azelo motorway interchange with A35. The A1 is plagued by high truck volumes and has a poor traffic flow throughout the day. Provincial governments lending money to the national government to speed up road projects are highly unusual, but both Gelderland and Overijssel province have a lot of cash because they sold their shares in utility companies a few years ago.

That's great news once again! Will that part be finished before the A1 stretch between IC A27 and IC A28 and the A1 between IC A28 and IC A50?
