The Spessart Bridge is a road bridge between Kreuzwertheim and Wertheim , which spans the Main at river kilometer 155.75 with the state border between Bavaria (in the Main-Spessart district ) and Baden-Württemberg (in the Main-Tauber district ). It transfers the state road 508 or state road 508 . The structure has two lanes as well as sidewalks and cycle paths on both sides.
history
The Spessart Bridge was built in the early 1990s to relieve the old Main Bridge and as an alternative connection between Wertheim and the Federal Motorway 3 at the Marktheidenfeld junction . It opened on November 17, 1992.
construction
With a curved opening, the structure spans Landesstraße 2310 and the Miltenberg – Wertheim railway line , the main opening over the Main and two further fields over the eastern flood area.
The prestressed concrete structure has the continuous beam as a structural system in the longitudinal direction . The maximum span above the Main is 96 m, the total span of the four-span bridge is 262 m. In the transverse direction, the 13.7 m wide superstructure is designed as a single-cell hollow box cross-section with a haunched construction height. In the middle of the field of the river opening, the construction height is 2.2 m, roughly half the height above the river pillars with 4.5 m. The prestressing consists of internal tendons in the longitudinal direction . The massive pillars and abutments are all clad in red sandstone .
The bridge section over the Main was built using cantilever .
