Information by Heidi Zahir:<br>Since 1935, a fünffeldriges bridge construction with steel concrete superstructure on the Werra in the direction of Creuzburg led on the outskirts Mihla. The bridge was damaged in the second world war, until 1954 was renewed the cantilever of the midfield and the lying on this slope applicator in the field 2. Checking bridges main 1994 proved to be the poor condition of the building of the bridge condition grade 4, also the capacity with only 16 tons ceased the traffic requirements in one pure traffic. Therefore, a spare new building of the bridge in the course of the L was 1017 dringed required. A bridge construction should occur, which balanced design is, blends harmoniously into the landscape and provides a sufficient flow height for the 100-year old flood (including 50 cm freeboard). Five different variants were examined to in relation to the planning of the new building. A special design, which included a vacuum-sealed prestressed concrete structure instead of the manufactured superstructure with a steel composite cross-section in otherwise complete compliance with the external appearance was given preference. With the start of construction on the 03.06.1996 a dreifeldriges building was until his graduation on the 16.07.1997, that 40.50 - 30,35 m visually balanced presents itself with its selected spans of 30,35 -. In spite of difficult conditions – at the bridgeheads, the plot was heavily restricted by a previous Avenue and extensive tree protection required - could be released the bridge on the 20.12.1996 for traffic.
