Viticulture has a long tradition in Heilbronn and is an important part of its economy to this day. Its 514 ha, two thirds of it growing red grapes, is the third largest vineyard in W�rttemberg's vine-growing region after Brackenheim and Lauffen am Neckar. In 1888 the vintners of the Heilbronn area combined and formed the Weing�rtnergesellschaft Heilbronn , a cooperative. In 1933 that cooperative then combined with the competing cooperative Winzergenossenschaft Heilbronn that had formed in 1919 and that cooperative again merged with the Vintner cooperatives of Erlenbach and Weinsberg to form the Genossenschaftskellerei Heilbronn-Erlenbach-Weinsberg with seat just outside the city limits in Erlenbach. In addition to the cooperative, numerous independent vintners are also located here.
South of the steam power plant is located the conveyor tower of the S�dwestdeutsche Salzwerke AG (SWS). The SWS runs a salt mine in the Heilbronn area. That mine was connected through an underground tunnel with the now shut-down (since 1994) salt mine Kochendorf in Bad Friedrichshall. Extraction had extended the Heilbronn mine far to the west so that in 2004 a new shaft, Konradsberg, was added � probably the last mining shaft that was constructed in all of Germany.
The city of Heilbronn is readily accessible by road courtesy of the Weinsberg Intersection just to the northeast of the city, the intersection of the Autobahn A 81 from W�rzburg to Gottmadingen and the A 6 from Saarbr�cken to Waidhaus. In addition to the Autobahns the city is connected via the Bundesstra�en B 27 from Blankenburg to Schaffhausen, B 39 from Frankenstein (Palatine) to Mainhardt and B 293 from Karlsruhe to Heilbronn that both run through the city itself.
Heilbronn is also a forerunner of right turn on red in Germany and 65 "Green arrow" signs have been installed at appropriate intersections since 1996.
