Holger Habich (FDP, but also supported by the CDU) was victorious. He was re-elected in 2013 and 2019. Coat of arms The town's arms might be described thus: Party per fess Or a lion rampant gules armed and langued azure and azure three waterlily leaves argent. The red lion rampant is from the arms borne by the old Counts of Katzenelnbogen. This same charge can also be seen in Darmstadt’s, Pfungstadt’s and Auerbach’s arms, and they are all parted per pale (that is, horizontally across the middle), just as Zwingenberg’s arms are. Town partnerships Pierrefonds, Oise, France since 1968 Brisighella, Emilia-Romagna, Italy Tetbury, Gloucestershire, England, United Kingdom since 1981 Eckartsberga, Saxony-Anhalt Economy and infrastructure Although the economy was formerly largely based on agriculture and winegrowing, as well as gastronomy, since then, besides a great number of commercial enterprises, a series of smaller and midsize technology businesses has arisen. Established businesses BRAIN Biotechnology Research and Information Network GmbH (biotechnological and genetic-technological research) Preussag Wasser und Rohrtechnik GmbH (water and pipe technology – environmental technology branch) PWT Wasser- und Abwassertechnik GmbH (water and sewage) Resin Express GmbH (plastic granulate distribution) SurTec Deutschland GmbH (chemical products and processes for surfacing technology) Transport Zwingenberg is linked to the A 5 (Frankfurt-Basel) by interchange 29, and Zwingenberg is also signposted on the A 67 at the Gernsheim interchange (8). Frankfurt Airport is 45 km away, and the riverport at Gernsheim on the Rhine is 12 km away. Parallel to the Odenwald runs the Bergstraße (federal highway B 3), which in Zwingenberg splits into the “New” and “Old” Bergstraße, which come back together again near Darmstadt-Eberstadt. The relief road originally planned for the B 3, called the Berliner Ring, is open in parts. The road, running parallel to the B 3, comes from Bensheim and leads back to the B 3 in Zwingenberg. Original plans to relieve the (very low – about 2.95 m) railway bridge by building another bridge farther north failed in the face of protests from residents and the neighbouring community through whose municipal area parts of the road would have run. One of Germany's most heavily travelled railways, the Main-Neckar Railway (Frankfurt-Darmstadt-Heidelberg/Mannheim), runs through Zwingenberg. Zwingenberg station is served hourly by Regionalbahn trains. These are reinforced by other trains in rush hours. Modern bus links of busline 669 run by Darmstadt's HEAG mobilo link the town with Jugenheim and Heppenheim. Leisure and
