YIT and Destia will build E-18 Koskenkylä-Kotka. The works will start this autumn. The builders of Hamina by-pass will be decided in few weeks, and the works should also be started this autumn.

A new project that will start also this year or in the first months of 2012 is Road 12 Tampere coastal by-pass. It consists on removing the actual coastal by-pass that has traffic lights on it with a 3+3-laned tunnel with 2 interchanges.

What's the Tampere Coastal Bypass? Tampere is over 100 kilometers from the sea.

Tampere downtown is situated on a narrow piece of land between two big lakes. The lakeside road 12 is a bottleneck, and there is a plan to replace it by a tunnel.

The tunnel will consist of two tubes, and there will be 2 lanes plus an emergency lane in both directions. There will be junctions at both ends, thus eliminating all the current traffic lights.



The black circle shows the position of the third junction, which may be built in the future. Tunnel stubs will be built at the first stage to enable the future expansion without a major disturbance to the traffic.

The deepest point of the tunnel will be 29 metres below the lake level. The steepest climb will be about 3%.

Any plans for Hamina-Vaalima?
At Russian side they are going to build 6 lines motorway till St. Petersburg in a few years. Then it would take 1.5 hours from Helsinki-border and 1.5 border-St. Petersburg, the whole way could take just 3.5 hours

Hamina-Vaalimaa will be started in 2013 or 2014, I presume.

This is unlikely to happen. The detailed planning is incomplete, and there is an open appeal case at the Market Court. The authorities say that most probably the works can start no earlier than 2015.

Atleast accurate planning of the section is starting in spring of 2012.

Loving the pics of all the Motorways/Expressways around Helsinki. A lot of people say Madrid has the best Motorway network for a city in Europe, but i think for its size, Helsinki cant be far behind. You compare it to London, city of 7 million, with a wider area of some 12 million people, and yet London has no real expressway network instead completely reliant on the Underground and suburban rail system which is at breaking point.

This is not true, most of the roads are very outdated.

No, they are not.

The main road network is based on six radial motorways and two semicircle rings (#1 and 3) connecting them. (There is the Ring 2, too, but it is incomplete, and it is not planned be a semicircle.)



Legend: Green: Motorway, red: non-motorway, blue: motorway under construction.

The oldest sections from 1960's have been almost completely modernized during the last 20 years. For example, no junction on the oldest leg of the road 1 is in its original shape, and four new junctions have been built. Most of the road 51 has been rebuilt to add new junctions and bus ramps and to reduce weaving. The other four roads were built according modern standards.

There is, of course, congestion during the rush hours, as on all downtown-bound motorways in the world.

What is rather a new phenomena, is the congestion on the outbound direction during the afternoon rush hours, especially in the west. That is an implication from the change in the metropolitan demographics: The families with children tend to move further away from the downtown, and the population in the area is constantly increasing.

Currently, the motorway part of the road 51 is being extended by 10 kilometres, and there are ongoing work to add third lanes between the rings 1 and 2 on the road 1.

Another common trend is that jobs tend to be less concentrated in downtown, with more traffic in suburban areas. This trend has been set in the United States and Canada, where the busiest freeways are all far from downtown.

You pretty much have to consider Vantaa and Espoo as parts of Helsinki.

One could easily argue that bad city planning is the main reason for that trend. Then again, if a city takes away parking spaces, increase parking fees and turn central streets into pedestrian zones, they really shouldn't be too surprised when people decide to go shopping at a mall in the suburb instead...

Agree. The same applies in the Helsinki area where a lot of jobs are concentrated close to the ring roads. On many radial roads, the heaviest loaded sections are those located between the rings:

Most of the radial motorways are 2x2-laned supporting AADT of 50 000 - 80 000, and Kehä I and III are partly 2x2-laned with traffic lights! Isn't that outdated?

Traffic volumes on the ring roads are high enough to warrant grade-separation, especially because the 30.000+ traffic volumes occur on the entire route, not just some spots. 60.000 vehicles on 2x2 isn't a very big problem.

Kehä I already has 2x3 lanes on the 80.000+ section. The Valtatie 3 / Kehä I cloverleaf is outdated though. It should have some direct fly-overs or turbines, or have at least a full collector/distributor setup for merging traffic.

I must say the Helsinki metropolitan motorway network is pretty much complete, only the downtown area lacks high-standard routes, but this is a perpetual problem for cities located on islands or peninsulas. Truck traffic from the ferries are another problem I suppose.
