The Northaven Trail Bridge in Dallas is the only known S-curved, network-tied bridge in the world and was set overnight.

Assembled away from its installation location, it has a structural weight of 362,873 kg (800,000 lb) and is designed to withstand a pedestrian load of approximately 201,848 kg (445,000 lb).

The engineers engaged a method that used a gantry system with a jack and slide system on top. This allowed for three-directional movement to fine-tune adjustments during setting and also account for misalignments.

The 61-m (201-ft) bridge connects multiple regional bicycle and pedestrian pathways.
