World’s First Large Bridge Fully Relying on Carbon Fiber Reinforced Polymer Hangers

The Public City Transport Operator (SSB) of Stuttgart is building in 2020 a network arch bridge of 124-meter span with carbon fibre reinforced polymer (CFRP) hangers. The use of CFRP for all hangers allows a reduction of the cross sectional area of those to about one quarter of an equivalent steel cross-section. The sustainability of the CFRP hangers is in comparison to those of steel impressive. Finally, the use of hangers made of CFRP is less expensive than of steel and gives more freedom for an aesthetic arrangement of the network.
