The Bundesstraße 45 is a German federal highway.

It branches off the Bundesstraße 3 in Wöllstadt[1] and leads south, goes through the city of Hanau, traverses the Odenwald[citation needed] and ends in Sinsheim.

[1] The strip between Hanau and Dieburg was originally built and labeled as the Bundesautobahn 683, while the Bundesstraße 45 went through the cities.

The A 683 was later downgraded and made part of the Bundesstraße 45.
