The E18 Hjulsta –Kista project aims in particular to improve passage and reduce accidents. A new local road between Hjulsta and Rinkeby will separate local traffic from transit traffic. The number of accidents will decrease when the conventional road intersections are replaced by grade-separated intersections. Many new bridges and passages will be constructed between residential areas and Järvafältet. Noise barriers will be constructed along large parts of the road. The work started in 2009 and is estimated to be completed 2015.
