 Two Class-A roads, E6 and E4 were originally scheduled to be renamed into E47 and E55, respectively.However, since Sweden and Norway have integrated the E-roads into their national networks, signposted as E6 and E4 throughout, a decision was made to officially keep the pre-1992 numbers for the roads in those two countries.These exceptions were granted because of the excessive expense connected with re-signing not only the long routes themselves, but also the associated road network in the area.
