Planning of 3 bridges including construction, temporary bridges, dismantling in the course of the B209 at Rethem
The “Allerbrücke” is a three-field bridge with a length of 98 m, follows the “Kleine pier”, a single-field bridge with a length of 25 m. Another 500 metres away is the “Great Pier”, a 109 m long Vierfeld Bridge. All 3 buildings have a width of 11.8 m between railings.
The need for replacement new construction results from the recallating of the buildings. Allerbrücke and large pier are to be replaced by replacement new buildings due to load capacity deficits. The small pier is to be replaced by a replacement new building due to stress corrosion cracking (not sufficient announcement behavior in the transverse direction).
For the construction phase, it is planned to maintain traffic by means of makeshift bridges.
