This is something really interesting! It will obligate Finland to finally upgrade Road 6/12 Hollola-Lahti-Kouvola and Koskenkylä-Kouvola + Imatra-Parikkala to motorway standards - construction on stretch Taavetti-Lappeenranta is already starting, and Lappeenranta-Imatra has been completed
Obligate? How? By whom?

Increasing traffic, the fact that Russians have a so fancy road just outside the border where the Finnish stretch is crappy, a flow of tourists and goods... ?

It's also interesting how we will still after the third stage of Ring III have two sections with too low capacity: E18(1)-Vanhakartano and Tikkurila-E75(4). I believe atleast the last, short one, with mostly third lanes already will be included in these third phase plans.

And of course the hugest shame of all, the long section of Ring III between Espoon Keskus-Road 51, a country-road with 1+1 lanes (AADT 25 000, busiest 1+1 in Finland), and increasing by 2025 to 22 000 - 70 000 with just an upgrading plan to 2+2 between 2020 and 2035. I think it will be accelerated though.

The only reasonable place to go, using higway 7 to Ring III west, would be the Länsimäki interchange.

Of course one can take highway 4 to Ring III even when going there. According to Google maps, it's only 1 km longer but 1 min faster.

But why?

You are suggesting closing an existing ramp because the main traffic flow will get a new ramp without any impact to the existing one. No sense at all.

As said, the ramp in question will be the main access route the new waste-to-energy power plant from the south and southeast areas of Helsinki. No sense to close it. The level crossing will not create much harm, because the traffic volumes at the Ring III south of the road 7/E18 are pretty low.

I'm suggesting this traffic to use Länsimäki route (new interchange on Road 7), or to build a full ramp without stopping traffic going towards Vuosaari harbor.

Truck crashes at railings of a motorway bridge at 7/E18

On Saturday Aug 17th noon there was an accicent on motorway section of the road 7/E18 in Porvoo, on valley bridge at the exit 63. A truck abruptly moved to the left lane, sevely damaging a passenger car overtaking the truck. The truck collided at the railguard of the brigde, and ended up being hanging supported by the railguards. The trailer dropped down
from the bridge and crashed on the road 11863 about 20 metres below the motorway. No person injuries occurred. The accident might be caused by falling in the sleep.







The location seen from the road 11863: https://maps.google.fi/maps?q=Ilola,...344.05,,0,2.36

Could anybody explain me, what the heck is the logic of this type of junctions? I mean, one of the roads could be free-flow, so why traffic lights and left-turns on both??



(The junction shown is Road 120 and Ring 1 in 1988, it's been improved since then).

Construction of bypass Hamina

Construction of bypass Hamina::

August 6, 2013
West adjoining the existing motorway Vt 7 (from Kotka, in the scheme - the left side of red area).

Panorama detour beginning of Hamina (Hamina) from Helsinki (where the section of the highway is now pumped from Kotka, Hamina up).
View of the east - in the direction of Russia:

In the reconstruction of the site blew up an overpass over the highway (visible in the upper half of the image), but built a new one (visible in the lower half of the image) - on a future motorway route:

In the present highway near the present site of Hamina is additionally installed soundproof barriers (view from the west - in the direction of Kotka, Helsinki).

At least that one has been improved...

The interchange of 3 and 65 in Ylöjärvi also has left-turns from all directions. The east-to-south and west-to-north directions also have illegal traffic lights: arrowhead traffic lights for left turns, but no traffic lights at all for the other lanes. Like this:

https://maps.google.fi/?ll=61.554273...84.11,,0,-5.16

And this intersection is only a few years old in its current form...

One question: Shouldn't the title of this thread be added with the Swedish title "Motorvägar i Finland"? It is a bilingual country, and I'm certain that some people are surprised to see some road signs such as those from the capital Helsinki/Helsingfors to be in two languages.

Ah, the double TOTSO at the end of the Tampere ring road.

Anyway, the main turning flows are S-W, W-S, N-E, and E-N. All of those are free from left turns. The points of conflict on the N-S level do not make harm to the main flows. The E-W road is controlled by several traffic lights. Thus, this interchange is not a single bottleneck to the E-W and W-E flows.

Quite clever planning, I think. Except for the illegal traffic light setup.

I would vote no. Most of the country is monolingual as you can see on the map:



Blue - Monolingual Finnish
Red - Bilingual, Finnish majority
Green - Bilingual, Swedish majority
Yellow - Monolingual Swedish

(The junction shown is Road 120 and Ring 1 in 1988, it's been improved since then).
You need to know the history in order to understand.

The original design dates back to late 1970's. The N-S road was recently downgraded from the primary road 2 to the regional road 120 (after the new alignment Palojärvi-Olkkala got opened). Closing the Kannelmäki-Leppävaara gap of the Ring 1 received a heavy resistance, as the traffic volume estimates were moderately low. For these reasons, both roads were built as streets. Both of the roads were full of left-turns and traffic lights, as the streets typically are. Thus, nothing special in this interchange.

As we know, the estimates turned false, and the traffic volumes exploded. The Ring 1 turned to be the busiest road in the country, and several expensive action points have been taken to make it a urban motorway-like road without level crossings.

The original design is not bad if you take a closer look. Every ramp end is a right-turn only. Thus, in all of the four crossings, the traffic flow at the opposite side of the merging point (the "top of the bar of the T") is free from conflicts. Therefore, at each of the four through-traffic directions, there was only one traffic light.

The interchange is located in a valley of a small river. The clay-based embankment of the eastern approach was badly undermined in the late 1980's, and it was rebuilt. At the same time, the interchange was upgraded to a parclo A4 by adding direct ramps in the directions N-W and S-E. That change removed the left turns from the Ring 1. Because there is no such thing as a free lunch, the road 120 suffered from this change: There are two traffic lights in both thru-traffic directions, thus decreasing the overall throughput.

That would be logical, considering all the other bilingual countries have bilingual thread titles.
