SUMMARY Hennebique-system by the activity of Szilárd Zielinski. Presently, the oldest reinforced concrete bridge in the county was built in 1907, while the most significant, relatively old reinforced concrete bridge was completed in Kehide-Kustány based on Zielinski's design in 1913. Actually, the originál structure is still under operation, although it has already been widened and strengthened. The three-span Zala-bridge was constructed by Andráshida. Its substructure was destroyed during World War II, the number of its spans was increased when reconstructed. The construction of reinforced concrete bridges became really widespread from 1923 on, slab bridges as - above 10 m spans - ripped girder bridges were built. In 1945. already fást 20% of the bridge stock (101) was reinforced concrete, alsó 210 timber and 204 arched bridges were registered that time. Among the arched structures, the two-span bridge at Nemesbük is famous. It was built in 1825 and still stands in its originál form. Besides, there are still 10 other arched bridges above 100 years under operation. During World War II, somé 200 bridges in the county were destroyed in 2 weeks. Of the longer bridges, the Zala-bridges at KehidaKustány and Zalaszentgrót, as well as the flood area Zala-bridge at Alibánfa could avoid the destruction. (The name of the saver of Zalaszentgrót-bridge is alsó known from the chronicles.) After this vast destruction, the construction of temporary bridges gave the possibility for traffic. In 1946-47, already permanent structures were alsó built. The reconstruction of the Zala-bridge at Balatonmagyaród was the only one with steel construction (Langer-girder arch). The superstructures of two Zala-bridges are low deck reinforced concrete arch: Fenékpuszta (1951), Zalaapáti (1959), this latter one prestressed deck arch. Unfortunately, arched structures were not reconstructed not evén in Zalalövő. FÜGGELÉK Till 1975, reinforced concrete slab, then frame edge slab bridges, pressurised plank then prestressed girder structures (from 1958 on), while - at the larger, multi-span Zala and Kerkabridges - spare hollow case, then case cast reinforced concrete bridges were constructed. At Zalaszentgrót, an EHG-girder bridge was built beside the old arched bridge. From this time on, further developed version of this bridge girder type (EHGE, EHGT) became widespread in the construction of bridges over 10 m span. After 1955, the reconstruction of small bridges was especially successful in county Zala, and, as a consequence, the timber bridge stock has quickly decreased. In 1965, the 15span Zala-bridge at Zalaszentgyörgy was still in operation. In 1967, there were only 41 temporary bridges on the national highways. The registration in 1977 contained no timber bridges any more. The bridge stock of the county is rather big: there are 440 bridges on the national highway network with the area of 49589 m

: There can be found 437 bridges managed by municipalities, 103 railway bridges, 25 forestry bridges and 50-100 priváté ones. The bridge stock of the county is continuously growing partly by the construction of settlement by-passes, partly due to the present motorway construction. Present publication is the 12* volume of the county bridges history series using the earlier editing principles: a huge number of figures, literature sources for further investigation. Several experts participated in the completion of this book: Gábor Bire county bridge engineer, Dr. János Farkas designer, Dr. Imre Gáli rubindiplomed engineer with Jáky-price, Dr. László Horváth archaeologist, museum director, László Szabó museologist, László Bárdosi and Lajos Vajda railway engineers, Dr. László Vándor director of Göcsej museum and the editor of the publication, Dr. Ernő Tóth, retired head of bridge department. Dr. Herbert Tráger retired senior counsellor was the reader and translated the summary to Germán. The English translation 218
