The city of Dublin, Ohio recently completed construction of a unique pedestrian bridge.
The opening was set for mid-March, but was postponed due to the COVID-19 pandemic. The bridge is now available to the public, but visitors are asked to social distance, not touch the handrails and avoid the bridge if it seems busy.
Called the Dublin Link, the bridge is the longest single span, single tower S-shaped suspension bridge in the world, according to the city.
The bridge is 760 ft. in length by 14 ft. wide. The deck is “S” shaped with a radius of 500 ft. and is anchored into the earth at the embankments. Four 65 ft. approach spans lead to a 500 ft. long suspension span. The cables were produced in Italy by one of the few companies in the world that makes the type of suspension cables needed for the S-shaped curve bridge. Then those cables were extensively tested in Germany before being sent to Ohio.
The deck passes through the “keyhole” of the main tower which is 169 ft. tall.
