Speaking with the Associated Press, state environment minister Rainer Loske explained that the changes were taking place for environmental reasons - namely to curb emissions from people driving uneconomically fast.
This is the first time a German city-state has imposed a general speed limit on the autobahn, although there are often speed limits in place during road work or in congested areas. The news comes as a direct contradiction to the German Chancellor's claims several months ago that Germany would not gain any autobahn speed limits under her government.
The city of Bremen is run by a centre-left government of Democrats and Greens, and as we previously reported, an autobahn limit would immediately cut emissions by 5% and up to 15% in the long term.
The good news for German drivers, though, is that Bremen's stretch of autobahn is just 60km long - meaning you should be out of there in around half an hour.
