Oslo Package 1 (Norwegian: Oslopakke 1) was a political agreement and plan for introducing an urban toll ring around Oslo, Norway, and making 31 investments to road infrastructure in Oslo and Akershus. The package was approved in 1988, and toll charges were introduced in 1990. It was supplemented by Oslo Package 2, which included a similar scheme for public transport. In 2008, they were both replaced by Oslo Package 3.
The entire plan involved investments of 11 billion kr in contemporary value, inflation adjusted to NOK 19.4 billion 2008-NOKs. Of these, NOK 4.8 were state grants, while NOK 6.2 billion was revenue from the toll roads. NOK 3.9 billion was invested in Akershus, while 7.1 billion was invested in Oslo. The company Fjellinjen was created to manage the toll collection.
During the 1970s, car traffic in Oslo greatly increased, and there was a political desire to speed up investments in motorways and tunnels in the city. This would allow increased capacity, and at the same time reduce the amount of traffic in the city streets. In particular, Rådhusgata, The City Hall Square and the areas around them were congested, and hindered people from accessing the fjord. During the 1980s, the politic environment shifted towards reduced public spending. In 1982, Minister of Transport, Inger Koppernæs from the Conservative Party, promised increased government grants to local authorities that introduced toll roads.
The first project was to build the Festning Tunnel, that would, along with the intersection at Vestbanen, allow The City Hall Square to become car free. In 1986, both the city council in Oslo and Akershus County Council set demands for a new toll ring scheme, requiring that the state grant extra funding equal to the toll charges: the krone for krone principle. This was similar to what had been agreed upon in Bergen. A report was made by the Second cabinet Willoch, where the initial project, Fjellinjen, was to receive an annual grant of NOK 230 million. While there was local resistance, the plan was popular in parliament.
