Financing E4 The Stockholm bypass requires both toll fees and a yearly increase in traffic in and out of the inner city of about 0,5%. The Swedish Transport Administration estimates that in 2035 Stockholm will have a 33% traffic increase in the inner city and 69% in the region.

In a referendum 2006 the citizens of Stockholm voted yes to a congestion tax to pay for development of both public transport and roads. After a trial period the parliament decided in 2007 to permanent the tax and also that the revenues be kept by the state. Between 2007 and 2015 nothing has been spent on public transport.

The promise from our politicians is that from 2016 some of the congestion tax will be allocated for building a new metro line in Stockholm, 15% to the metro and 85% to the Stockholm bypass. 60-70 billion to the road and 9 billion to a new metro line until 2053.

In 2011 Svevia, an independent public company which builds and operates roads and infrastructure in Sweden, estimated what can be built with one billion Swedish crowns.
33 km of motorway on the surface in the countryside
1 km of motorway in a tunnel.
0,9 km of metro tunnels in Stockholm
25 km double track railroad in the countryside
5 km tracks for Swedish high speed trains
500 km of walkways and bicycle roads

Building a metro is costly but if the sum is divided between the number of passengers and kilometers a metro tunnel is by far the best investment.

The Swedish Transport Administration has created a formula that proclaims the Stockholm bypass to be a valuable time saving investment: One minute lost by a motorist is given a higher economical value than a minute lost in public transport. When the cost of the project increases the Swedish Transport Administration boosts the value of time for the motorist to save the socioeconomic calculation.

The Swedish Transport Administration estimates a travel time of 15 minutes through the 21 km long expressway. This gives an average speed of 84 km/h. This is an impossible speed in rush hour traffic and when the bypass is close to its maximum capacity of 140 000 vehicles per day. The prognosis is that max traffic will be reached within 15 years of opening the road.

The Swedish Transport Administration also calculates 10-15 traffic incidents per day and that accidents where one or more lanes needs to be closed will occur a few times per week.
