A unique stacked tunnel in Hilversum (NL)

In the US we would haven bulldozed all the buildings, the trains, and the bus way and put in a 8 lane highway

"When signs are need to forbid something, that is always an indication of a design flaw"
That is one of the most outstanding statements I have ever heard

I live near this tunnel. Took a long time to complete but I now cycle it regularly - safe and quick!

[niceone]

First I thought they turned the car underpass into a cycling underpass. But this is also a genius idea with great space usage.

[basengelblik]

I live here. Everybody including myself were super sceptical. Now I feel like an idiot. This is a lovely solution.

[fireskorpion]

That must also be so much more pleasant, to be separated from car traffic! Additionally it won't have to go as deep as a shared car tunnel. GENIUS!!

The perforated aluminium wall is also an acoustic absorber, reducing noise level inside. I believe the irregular decorative patterns also help diffuse reflections which reduces that annoying tunnel-y flutter echo.

Haha nice, I drive through that tunnel almost every working day, and cycle through it once or twice per week. It's great, and a big improvement over the old situation, where the passing trains closed the road for a substantial amount of time every hour. It was a real problem for the emergency services, and inconvenient for all road traffic.

The contractor ordered a full color, 3D printed, 1:300, scale model where I worked at the time. It was used for the residents near the construction plan, to be able to view the plans and discus it if they found necessary. It was a huge and awesome print. Never tought to see it on your channel, nice video!

this tunnel has like 4 levels of things american infrastructure would never even try to do

first, a tunnel JUST FOR bicycles
second, the car tunnel is deeper and longer in benefit of the bicycle tunnel
thirth, the tunnel was made to not disturb public transport
fourth, the tunnel was needed, bc they wanted to broaden the train railway, with a with a bus lane

Also interesting to note: the bus way on top can also be used by ambulances from the nearby hospital.

Actually, the motorway tunnel in Maastricht (A2/N2) is also a stacked Tunnel, but this one is still unique because it does not stack just road traffic.

In Maastricht there's the Willem Alexander tunnel. Also stacked. bottom lanes are for continuing traffic, top ones for local traffic. Before, this stretch of about 2km, used to have 6 traffic lights. The only 6 lights from Amsterdam to Rome on the A2/E25. Gotta love tunnels!

[Squizie]

Very interesting concept, I like such outside of the box solutions. Will keep this one in mind, as it could be a solution that could be applied elsewhere too, and I work on such kind of projects all the time.

[Aeyekay]

The level of dedication of the Dutch and their engineers is unreal

[eddys.]

I guess you've forgotten to mention one of the reasons for building this tunnel : the times per hour the railway-crossing was closed to road traffic due to the intense traintraffic, effectively splitting Hilversum in two.

[jolanpiep]

Hilversum is my hometown, and I grew up there my entire life! It's interesting to see this project *finally* finished. Especially since I havent seen it in person myself (yet)!

[ashleymalamute]

I love it how borderline infrastructure in the Netherlands would be next level, out of this world in Australia.

[albertsplinter]

The A2 motorway tunnel in Maastricht is a stacked tunnel too. The lower level is for trough traffic and the upper level has a more local acces function.

It is actually a big improvement. I went to school near that place. Traffic was always backed up from 8am to about 9:30am and from 4pm to 6pm. If it happens sometimes it might not be that big of a deal, but if traffic is consistently stuck between certain timestamps then there is a structural problem. Glad they resolved it.
