Engineering and Design
The Greig Street Bridge is a classic example of a suspension bridge, a design where the deck is hung from cables supported by towers. Constructed for a total cost of £1,400, the bridge was engineered by C. Manners in collaboration with the Rose Street Foundry.
The structure is characterized by its specific span measurements and safety features. It consists of a central span of 61.3 metres (201 ft) flanked by two side spans of 20.4 metres (67 ft) each. To ensure stability and pedestrian safety, the bridge utilizes warren trusses—a design consisting of longitudinal members joined by angled cross-members to form triangles—alongside protective railings.
To maintain its structural integrity over the decades, the bridge has undergone key renovations. The original cables were replaced in 1952, and the anchorages—the heavy structures that secure the cables to the ground—were updated in 1989.
The "Bouncy Bridge" Phenomenon
Beyond its architectural value, the bridge is famous for a local rite of passage. Young people in Inverness often gather a third of the way across the span to jump up and down in unison. This synchronized movement creates a physical oscillation known as the Greig Street sine wave.
This rhythmic bouncing has earned the structure the nickname "The Bouncy Bridge," a title it shares with the similarly designed Infirmary Bridge located further upstream. While the experience is a source of amusement for the locals, the resulting movement is often a surprise to unsuspecting tourists crossing the river.
