The E6, between Gardermoen and Biri, has been a two-lane motorway since 1994, however traffic volumes have significantly increased since this time and even doubled in some areas. Heavier traffic volumes have resulted in longer and more unpredictable travel times going northbound from Gardermoen.
Expansion of the E6 into a four-lane highway will more than double the traffic capacity, while ensuring there is sufficient capacity in the future and making current travel times more predictable.
The Gardermoen to Biri stretch presently has a high accident rate, with accident sites equally distributed along the entire stretch of motorway.
Since January 1994:
Transforming the existing two-lane motorway into a four-lane highway will significantly contribute to lowering the number of accidents between Gardermoen and Biri and reduce fatalities by up to 80 percent. The addition of a safety zone in both directions will cut down the number of accidents involving injuries occurring when motorists exit the carriageway.
