600m long road bridge
City of Lucca
modostudio / Knippers Helbig
The bridge with an overall length of 600m spans a wide river bed outside the town of Lucca.
The bridge serves both as an additional route for heavy traffic as well as providing a possible crossing for pedestrians.
As cross-section an asymmetric reinforced-concrete cross-section was chosen, whereby the vertically offset footpath is shielded from the noise of the traffic.
The bridge superstructure is designed as a continuous girder which in addition is pre-tensioned in the area of the 90 m wide main spans.
Construction is to be realised based on the cantilever principle; the subdivision of the bridge geometry in circular segments thus making the construction process comparatively easy.
