More peace of mind for the residents and safer Smestad junction:

Store Ringvei from the top to the bottom of the picture-disappears under the ground as a thoroughfare in the early 1980s. In 1979, Oslo Veivesen expects to start major construction works, which will solve the problems both for residents along this heavily trafficked and narrow main road and for 35,000-40,000 daily road users. two floors underground, both under the current road junction with Sørkedalsveien (from left to right in the picture) and under the tram line that you see runs parallel to Sørkedalsveien. The Smestad crossing (middle of the picture) is today one of Oslo's most difficult, with kilometer-long queues during rush hour. Both through traffic in the direction of Drammen - Hamar (E-6 and E-18) as well as local traffic to and from Oslo centre-Roa- Holmenkollen etc. pass here.


 In the early 1980s, motorists on Store Ringvei in Oslo had to drive in a tunnel under the current Smestad intersection. The work to rebuild the heavily trafficked road junction and 2.4 kilometers of Store Ringvei will start in 1979.
This will be a problematic road system. We have to rebuild Smestadkrysset and Store Ringvei while the traffic is at full capacity. We have no alternative roads on which the large number of vehicles can be diverted, says planning manager Bernhard Sæland in Oslo Veivesen.
But he assures that when the facility is completed in the early 1980s, the result will be beneficial both for residents along the heavily trafficked stretch of road and for road users themselves. Both pedestrians and drivers will travel safer. Traffic will be diverted faster and more effectively, especially during rush hour, where there are currently long queues both on Sørkedalsveien and on Store Ringvei at Smestadkrysset.
More peaceful residents along the 480-metre new tunnel will find it more peaceful, because the traffic is routed underground. But during the construction period, the road authority has to "borrow" a bit from many villa gardens in order to get enough excavated along the tunnel route. In those years, quite a few residents probably had greater disadvantages, more noise and dust than they have today. But when it's all fair-
you, they can enjoy safer and calmer conditions...
Double price
The Smestad junction and the 2.4 kilometer long four-lane Store Ringvei that is being built will cost approx. NOK 170 million, according to preliminary calculations.
It was the tunnel that made it more expensive
A 480-metre-long tunnel will be built to lower the Store Ringvei "two floors" below ground. The tunnel will carry traffic both under the current intersection with Sørkedalsveien and under the tram lines to Østerås and Kolsås. The tram already runs under the current intersection.
this road project to become one of the most expensive in Oslo.
- It is at least twice as expensive to build a tunnel as it is to build a road. In this case, we calculate NOK 55,000 per running meters of road, and NOK 120,000 per meter tunnel, says planning manager Sæland. He says that just retaining walls along parts of the road add up to approx. 12.6 million.
NOK.
There will be several two-level intersections along the new section of the Store Ringvei from Gaustad to the Smestad intersection. Currently, there are four two-level crossings, which will clearly lead to better traffic safety.
Certain roads are closed for exits on the Store Ringvei. Holmenveien, Dalsveien, Jon Smestads vei and Montebelloveien. and the Smestad junction itself is planned as a two-level junction.
In time, it is intended that the entire Store Ringvei will have a two-level intersection, from Manglerud in the east to Vækerøveien in the west, says planning manager Bernhard Sæland - who does not dare to say anything definite about when this can be completed.
