Renaming them seems logical, but since they pass through low density areas in Sweden it probably won’t ever happen.
Their E4 and E6 are the only exceptions to the naming convention, that north/south are odd numbers and west/east are even numbers. E4 and E6 should have been renamed in the early 1990s to E47 and E55, but they got to keep the old names in Sweden, because nobody wanted to pay for changing thousands of existing road signs.
Should reroute it via the Øresund bridge and tunnel.
The bridge is already occupied by the E20.
But 45 > 20, so get out of the way.
E45 used to be E6 before the bridge was built.
