The cost of the reconstruction is rather high due to some special issues:

1) A new bridge was built between the existing two bridges over the Espoonlahti bay. The old highway bridge (140 metres long, 2.2 million kg in weigth) was pushed 1.4 metres to the north in order to make space for the new bridge.

(The southertmost bridge from year 1937 is protected as a memorial. It was that time a very modern bridge, and between 1944 and 1956 it was located at the border of Finland and the Porkkala area acquired by the Soviet Union.)

2) In the Jorvas valley, the soil is soft clay and the solid bedrock is about 20 metres underground. The road structure built of concrete rests on several hundred concrete poles thus being more or less a bridge.

In my opinion, it is used very often ...

It is used on all the main roads to emphasize their status. In most cases, it is overhead, as the give way signs or the traffic rules show the priority order. If the speed limit at the crossing is 40 km/h or above, it is mandatory to set up give way signs (or warning signs about a non-priority arrangement where the right-hand rule applies).

The system is rather different from the one seen in Sweden and Germany, for instance, but it works rather well.

BTW, the sign has a side-effect: In non-urban areas, it implies a parking prohibition on the carriageway.

Give way signs are often used, but if you are at the main road you don't see it and may think this is a crossroad of equal roads

No you do not. If the speed limit is 40 or higher, and you do not have the yield sign, the crossing road should have one. The roads are equal only if there is a warning sign indicating that.

Those coming from private roads, minor roads, parking places, service areas, home zones etc must yield by a rule, as well as those entering a motorway.

Route 51

Doing some experimenting on driving videos (junction charts).

Really nice job! Must have been a lot of work.
Did you find the signs and junctions somewhere or did you all do by yourself?

Luckily those bus lanes will be normal lanes after the subway is completed - it's so disgusting to see at rush hours a whole almost empty lane and two lanes filled with cars.

As the bottleneck at the end of the motorway remains, the result will be slightly shorter queues on three lanes.

BTW, there is no final decision on converting the bus lanes to normal ones. As the coming subway significantly increases the travel times compared to the current bus system, there might be a transition period to run the subway system and and the bus system in parallel.

The junction charts are based on my earlier vector drawing project, so this time not a big job. (Needed to rotate them by 180 degrees and to drop some elements to keep them simple.)

Another option would have been to use the open road vector data nowadays available to the public by the National Land Survey of Finland. The ready-rendered maps need a cleanup to show only the essential roads, and that would quite an effort. An alternative approach is to do the rendering using Oziexplorer for example (as it can read ESRI shape files), but that would need some post-processing, too, to show the bridges. I postponed this approach to the indefinite future.

I made the direction signs. I have a few generic powerpoint charts to build on: A default junction, a urban motorway junction, a junction for a main road, a partial junction only for entrance, etc. The signs on the video are not exactly what can be seen on the road, but simplistic ones to avoid cluttering (and to keep them rectangular to avoid the need to play with the chroma keys). The warning signs were downloaded from the official site of the transport agency.

Oversize Transport Hits a Gantry

Early today, an oversize transport hit a gantry on the Ring 1 of Helsinki, and caused major delays to the westbound traffic. It is unclear why this vehicle was on the Ring 1, becase the road does not belong to the network of special transport routes.

Aren't there clearance overhead signs?

This gantry is high enough not to warrant some kind of special clearance warning. This transport looks at least a meter taller than regular trucks.

The maximum height of vehicles is 4.20 metres. The higher ones are special transports needing a permission from the road admin. The permission is based on route planning over official special transport routes, and it may contain a lot of terms and conditions related to weights, allowed hours, and traffic guidance.

All gantries and other obstacles with the clearance under 4.40 metres are to be signed.

So someone at road admin screwed up bad.

I do not think so. Most probably the transportation company have decided to skip the step to apply for a permission.

Accidents related to low bridges are not uncommon in Finland. Most of them are results from a careless route selection.











There is a number official transport routes having no gantries and low-clearance bridges. The Ring 1 definitely is not a part of this network due to a zillion of gantries, and being the busiest road in the country.

Truck fell down from ramp

Today afternoon, a truck crashed into a bridge railing at the junction of routes 3/E12 and 9/E63 south of Tampere: https://maps.google.fi/maps?q=lakala...mpere&t=m&z=16

The truck was climbing to the 3rd level of the 4-level half-stack junction, went through the bridge railing, fell down several metres, and bursted into flames. The driver managed to escape the vehicle before the fire, and got minor injuries only.

The east-to-south ramp is expected to open no early than tomorrow morning.

Joensuu bypass

Joensuu bypass on the roads 6/9/23 is being upgraded into a motorway. After completion, it will be the easternmost motorway of the continental EU.

This 25-km-stretch won't be connected with any other motorway, though.

The completion of the project is expected in 2014, but the first sign portals are already there:

http://www.karjalainen.fi/fi/uutiset...myos-venajalle

Sortavala has returned as a signposted destination in Joensuu. It disappeared after the World War II, as the Soviet Union annexed Sortavala (among some 12 % of the Finnish territory) and the main road connecting Joensuu and southern Finland was rerouted via Lappeenranta.

Despite the new sign, the part of the road 9 leading to the Russian border is not affected by this project. Although it was reclassified as a highway just a few years ago, this was merely an administrative action; no remarkable road construction or upgrading took place on that stretch.

Interesting project. It's visible on Google Earth imagery.
