Urban roads / motorways

I was thinking about Sydney's road tunnels and how many they have, it really is amazing. Probably one of the most extensive in the world.

Sydney has:
The Sydney Harbour Tunnel
The Eastern Distributor
Cross-City Tunnel
M5 East Tunnels

and then they're also building the Lane Cove Tunnel

and there are several others proposed:
M4 East
Spit Tunnel
F3-M2 Link

Post pictures or map's of your city's underground road network.

Sydney has a great selection of tunnels, but it is nowhere near the most extensive in the world. There are many other cities with more road tunnels than Sydney.

Actually, there was a thread over a year and a half ago where people listed these

Croix-Rousse
Fourvière (all Northern Europeans going on holidays in southern France or Spain know this tunnel and its traffic jams)
Periphérique Nord (3 tunnels under hills and river)

I came across this pdf on Road Tunnels in Oslo, it mainly describes one particular tunnel, but has a map showing the others (I don't know if it's all the tunnels)

Thought it'll be worth posting here:
http://www.tunnel.no/_upl/kapitel%205.pdf

Seems to list the following tunnels:
Valerenga Tunnel: 0.7km
Ekeberg Tunnel: 1.4km
Oslo Tunnel: 1.79km
Granfoss Link Tunnel: 2km
There are more tunnels that are no listed, and others planned (this document seems to be from 1995)

Not bad for such a small city.

Not a surprise for me that Paris is "the capital of road tunnels": it simply has an incredible amount of tunnels

In Italy surely road tunnel capital is Rome

The reason Zürich has so many tunnels is becaus of its topography.

Rome, Italy

I don't think this is all, maybe just the city proper and only over 500m

Total: 17.740km

Genoa, Italy
Now, the metropolitan area of Genoa in Italy has the most amount of tunnels I have ever seen in my life, in fact, it has one of the greatest entrances by road of any city I have seen in the world. Either from Milan or Nice, you travel via endless bridges and tunnels until you hit the overpass that is between the harbour and incredibly dense city center that cradles the hill side. It is simply breathtaking to enter by car. There are so many tunnels here as the steep hills divide the urban area's and require tunneling to connect (or bridges). There are so many steep hills, Genoa has the largest remaining number of public elevators in the world to reach the higher suburbs, as well as a number of funicluars. This list is for the metro area and only above 500m.

I think there is a difference in 'urban' feeling between long tunnels through mountains in metro area, and proper traffic tunnels in city centre.......

Thought it'll be worth posting here:
http://www.tunnel.no/_upl/kapitel%205.pdf

Seems to list the following tunnels:
Valerenga Tunnel: 0.7km
Ekeberg Tunnel: 1.4km
Oslo Tunnel: 1.79km
Granfoss Link Tunnel: 2km
There are more tunnels that are no listed, and others planned (this document seems to be from 1995)

Not bad for such a small city.
Yeah, we have alot of tunnels, and there are more to come. All those listed have 2-4 lanes in each direction. And so does:
*Svartdalstunnelen
*A tunnel at the nothernmost point of ringroad 3
* Sentrumstunnellen, going under parts of downtown. Part of ringroad 1.

And some of the new tunnels beeing built:
* Bjørvikatunnellen. Will go at the sea-bottom in the Bjørvika bay. It will have 3*2 lanes and lots of smaller tunnels connecting it to the road-network. The work on it has started not long ago. You can read more on what will happen on the ground above the tunnel in the fjordcity thread.




* West corridor. This is just on the planning stage yet, and the financing and timing isn't 100% yet. 3*2 lane motorwaytunnel going under the very important west-corridor, from Skøyen to Asker, aproximately 15 km long. This is the most trafficated road in Norway with some 100.000 cars passing each day. The current motorway will be used to serve local traffic. Most of it the new road will be tunnel, but I don't know how long the longest single piece of tunnel will be.

Here we see how parts of the current motorway is intended too apear after the tunnel is built.




*Økerntunnellen. This is located on ringroad 3, work started this summer. 1,2km 3*2 lane tunnel, and one smaller 2 lane tunnel.




There are also talks of putting a lid on the biggest motorway going out of the city eastwards, and other projects.

I heard that Boston, MA tunnel system is one of the biggest engineering projects undertaken in the states in some time, they got all the multigrade interchanges underground or something.

Genoa, Italy
Now, the metropolitan area of Genoa in Italy has the most amount of tunnels I have ever seen in my life, in fact, it has one of the greatest entrances by road of any city I have seen in the world. Either from Milan or Nice, you travel via endless bridges and tunnels until you hit the overpass that is between the harbour and incredibly dense city center that cradles the hill side. It is simply breathtaking to enter by car. There are so many tunnels here as the steep hills divide the urban area's and require tunneling to connect (or bridges). There are so many steep hills, Genoa has the largest remaining number of public elevators in the world to reach the higher suburbs, as well as a number of funicluars. This list is for the metro area and only above 500m.

Rapallo: 2380m
Madonna della Guardia: 2126m

I think for Genova most are "non-urban" tunnel
There is a project for a tunnel under Genova Harbor

For Rome: road tunnels are many more and many are planned to be built

Recently they opened Pineta Sacchetti tunnel (you listed it: it's Giovanni XXIII°, but its lenght is 3.5 km)



They're planning a tunnel under Appia Antica with a total lenght of about 9 km

In Milan there are few tunnels: they talked to build a "tunnel web", a ring tunnel around historical center of about 12 km and others, in project financing
But, really I don't know if this project will become reality

There is an interesting road tunnel in Lecco, in Milan metro, on Como Lake: it crosses the whole city to permit to link the upper tranch of Valassina motorway with Southern one, without "enter" the city... really cool and long tunnel (I don't know how many long, I think about 10 km maybe more)
It has several exits to "go up to the city
