Major roads Lund has been connected to the motorway network since 1953 when the E22 was opened between Lund and Malmö.

The E22 forms the main north-south trunk route through Lund. The largest east-west road is the multi-lane northern ring road which also passes through the city limits. There are also other connections to most major roads in the area, for example the E6 via Riksväg 16, and the Länsväg 108 which connects to the E65.
