The deck and the compression members of the triangular trusses are made up of GL-28h glue-laminated-timber beams while the tension members are steel bars. An access four-span ramp has been designed to allow for river widening during flood periods.

Timber protection details have been thoroughly designed to improve durability and to reduce maintenance needs as much as possible. The footbridge has a timber decking.
