The last remaining traffic-lights on the heavily loaded sections on the rings are currently being removed.

There is a huge buidling site on the Ring 1 and road 1 in Leppävaara to modernize four existing junctions adding collector lanes, to build two new junctions, and to build a 4+4 lane tunnel. Most of the new routes are already open, even if the work is due to be complete in 2012. After completion, all junctions between the roads 1 and 4/7/E4 will be grade-separated.

A second building site lies on the Ring 3. The remaining traffic lights were already removed, two new junctions will be built, three junctions will be updated, and the parclo junction 3/Ring 3 will be completely rebuilt to a 3/4 cloverleaf.

The Valtatie 3 / Kehä I cloverleaf is outdated though.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.
That junction is not very problematic nowadays. The west-to-north traffic flows on an ad hoc ramp, but without major problems. After the lates upgrades, there is no weaving on the thru-traffic lanes, but the merging ramps continue as new lanes. (This does not apply to the southbound traffic which is supported by a collector ramp, and a normal merging lane.)

I do not believe there will be any major changes to the setup during the next few decades. The south-east sector is the only one where there is enough room to build new ramps. The existing narrow forest strips are planned to remain as noise barriers.

I don't know how old are that AADT dates, but officcially Kehä I has an AADT of ca 110 000 between Road 3 and Road 45 - to switch from Espoo direction towards Tampere you must turn right after the parclo, go to an 1+1-laned residential street and turn left from it.

I think Espoo had plans to start upgrading the restant section of Kehä I from Road 51 to Turku motorway to motorway-standard in 2012 or 2013 - in Helsinki nothing ever happens.

The upgrading of Kehä III from western Espoo to Airport and from Road 4 to Road 7/E18 to 3+3/4+4 lanes and high standard will hopefully start in 2012.

Transport Aircraft Lands on Highway

There are a number of so called emergency landing strips on the Finnish roads. They are temporary military airfield to be used by fighters. Today, the Finnish Air Force CASA C-295M made a succesful landing on the Lusi strip on the road 5. This was done to test the capability to operate that aircraft type at such an airfield.

The wing span of the aircraft is 26 metres, and the clearance between the trees is 45 metres.

How Things Change

The map of the Leppävaara area west of Helsinki from 1960 shows rather a rural area with some suburban structures:



The first motorway section of the road 1 is being built. The road was complete in 1962 and the old road shown to the north of the railway was turned to a local road.

Then population in the Helsinki region doubled in 50 years. The map from 2008 is rather different from the previous one:



The north-south road is the Ring I of Helsinki, one of the busiest roads in the country. The junction of the road 1 and Ring 1 (the 3/4 cloverleaf) has already been rebuilt twice. Thus, the map shows the third version. The big pink area at top-left is a large shopping mall, and a terminus of the local buses and commuter trains.

The junctions at the area are outdated, and the whole section of the Ring 1 has turned a bottleneck. There is no room to add lanes in the area north of the railway. In addition, the section north of the railway cause noise problem to the homes nearby.

The whole area is being upgraded during the years 2008-2012:



Two new junctions E9 and E11 were built, the complex junction E5 was almost totally rebuilt, and the junctions E6, E7, and E8 were slightly improved. All traffic lights on the Ring 1 were removed. The section to the north of the railroad was replaced by a twin-tube 4+4 lane tunnel. In addition, third lanes were built on the road 1 between Ring 1 and Ring 2. The section between the tunnel and the road 1 was equipped with new collector ramps. Thus, at the widest point the Ring 1 will be 3+2+2+3 lanes.



Construction works at the southern and of the tunnel

There is a clickable map at http://keha1leppa.pp.fi/ts/kartat/ to show detailed technical plans (with annotations in Finnish...).

The planning maps are available at

http://www.ely-keskus.fi/fi/Liikenne...ments/T1_1.pdf (West section)

http://www.ely-keskus.fi/fi/Liikenne...ments/T1_2.pdf (East section)

The green color displays the new or upgraded roads.

The right edge of the page http://www.ely-keskus.fi/fi/Liikenne...unnitelma.aspx (in Finnish) contains links to the detailed plans at a scale 1:2000.

Some key figures:

- 15 km new motorway
- 15 km other roads and streets
- 4 new junctions
- 2 junctions upgraded
- 2 short tunnels
- 43 new or upgraded bridges
- 14 km noise barriers
- 30 km animal fence
- 38 km illumination

Flooding

Excessive rain has caused some trouble in Finland. The motorway 1 Helsinki-Turku is partly closed in Espoo due to flooding. The road is in danger to be closed.

The Empire Strikes Back: The motorway was built in 1956-1962 by drying the lake. Now the lake is back again.

No snow in Finland either ??? Gosh ... The whole Europe is like that this year ...

Do you take advantage of the lack of snow to build these new roads as they're doing, for instance, in Poland ?

There is snow in Finland, but not in the south.



Depth of snow as of yesterday

The winter weather varies a lot. Last year this time, there was 50+ centimeters of snow even in the southernmost areas of the country.

Snow is not the issue for building the roads, but frost. The road structure must be robust enough to stand the ground repeatedly freezing and melting every winter and spring. Thus, the lack of snow in some years does not help much.

The need for a robust freezing-resistant road structure makes it rather expensive to build roads in the arctic areas.

The bedrock on large areas on the Åland islands and the southwestern mainland of Finland is composed of red granites. That rock is used for making asphalt, too, and the result is striking red.

Snow Causing Problems

The Southern Finland has received some 20-25 cm of new snow yesterday and today. As the temperature is close to zero, the snow is thick and rather wet, thus making the roads and streets extremely slippery. Some problems have arised.
