A4 Leiden

A new configuration for A4 at Leiden caused traffic headaches during rush hour. The roadway had three lanes, which is now divided in 2 through lanes 1 local lane. Critics of the local/express setup already warned that 2 through lanes are not sufficient and 1 local lane is not flexible enough. The result: a 12 kilometer traffic jam. While some of the congestion may be attributed to the new situation, it is unlikely to completely resolve after a while.

Unfortunately many politicians want to push for a local/express setup at locations not suited for it. The whole "separating through and local traffic" concept is quite popular among politicians. Traffic engineers are less fond of it, splitting capacity makes the road less flexible to handle peak traffic volumes and is more expensive to maintain and operate (specifically snow-clearing and workzone layout).

And I'm not sure whether that section of the Bredaseweg actually is N282 or a numberless-road (aka just Bredaseweg).

Why did they do it near Leiden though ?

Due to works or so ?

The "final" configuration of A4 at Leiden is a local/express configuration with 2 through lanes and 1 local lane to serve two exits (from 2019 also the interchange with Rijnlandroute)

This design was finalized in the mid-1990s when traffic volumes were considerably lower than today. As you may remember, the original EIS for this project was annulled by the Council of State around 2007-ish. They had to redo this project and did not want to risk any more delays for the A4 widening to 2x3 lanes at Leiderdorp, so the 1+2+2+1 layout stayed in the design.

Can it be expanded easily or is it also small dimension wise?

One extra through lane as well as one extra parallel lane can be added. Space reservation is there.

Pffff, anyone who has driven that route knows that 2x3 lanes are needed for through traffic. 2x2 for ''through'' traffic is not sufficient in that densely populated area.
Space reservation is one thing, the formalities are another...

Before the A4 was widened, I was surprised such a major route was only 2x2...
Politicians love local/express setups, makes no sense at all for 2 exits though, I can see how it has its advantages in some situations, but not there...

local express is great but you need at least 3 (or really, at least two) lanes on each carriageway...

A pleasant rendezvous on the A2 Maastricht tunnel. Removal of material advanced a lot. This will be a double deck tunnel.

N69 Eindhoven - Belgium

The province of Noord-Brabant published the design EIS for the new N69 south of Eindhoven.

The plan is to construct a new 1x2 80 km/h road that bypasses the towns of Valkenswaard and Waalre. The entire road will follow a new alignment to A67 near Veldhoven.

Unfortunately, it will not be constructed as a four-lane highway as planned in the 1970s. The forecasted AADT is 19,000 vehicles per day, so the new N69 will be pretty much at max capacity.



AADT change:

Will the alignment be conflict free at the A67 junctions and at other junctions?

Do these figures include the expenses by watershed boards?

No, water boards have their own budget. This also does not include the Delta Fund. The waterways expenses of the Infrastructure Fund are chiefly that of canals, sluices and some port infrastructure funded by the ministry.

N359, Lemmer

Provincial and municipal governments have decided not to pursue a new alignment for the N359 project around Lemmer. This would cost too much, and have too much impact for relatively limited traffic problems. The main culprit is a bridge across a canal called the "Sylroede" that opens very frequently during the summer yachting season.

The province of Fryslân wants to invest almost nothing, while the municipality of De Friese Meren wants an aquaduct. The province seem to backtrack its original position to construct an aquaduct, the cost of which was estimated at € 28 million back in 2010.

1. Cancelled variant: N359 north


2. Cancelled variant: N359 south

Due to an accident which involved a truck on fire in the Heinenoordtunnel (A29) has been closed in both directions. The direction to the south is where the accident happened and will not open before tomorrow may 22nd at 06:00 hours. Sadly enough 1 fatality was recorder after the accident.

It shows the vulnerability of the highways around Rotterdam where still major improvements are due. Especially the missing link in the A4 to the South is painfully felt here. Between the Haringsvlietdam and the Drechttunnel near Dordrecht there is no real acceptable alternative to reach the Southern part of the Province Zuid-Holland and to reach the provinces Zeeland en Brabant.

Luckily the construction of the A4-MD (a 7 km stretch between Schiedam/Vlaardingen and Delft, which is another missing link) is now well underway with only a "slight delay" of just over 45 years (!) and will open at the end of 2015 instead of 1970!!! Still to be build is the Blankenburgtunnel between Rozenburg and Maassluis in the western part of the region.

That A4-South link is badly needed. It is as simple as that. The effects of the missing link can easily be seen here:

I think a closure like this would have created traffic problems in any country.

But this route has no good alternatives. The N217 was entirely jammed from A29 to A16, the reported delay was 2 hours on that route, and then the traffic jam on A16 as well... In addition, there are road works with lane closures on A16, so even if you wanted to avoid A29, you still have to get into traffic congestion.

An extended A4 would have definitely helped to improve access. The A29 Heinenoord Tunnel is the only tunnel from the Hoekse Waard area to Rotterdam. There is a small ferry at Spijkenisse, but is not designed for any major traffic volumes.
