Gerald Sulivan, president of Mari-Tech Scales & Food Equipment Inc. in Nova Scotia, along with co-owner Stewart Greig, have been Rice Lake distributors since they launched the company 11 years ago. Gerald is taking us to see Rice Lake equipment applications on Prince Edward Island.

There is only one way to get there, and that’s the beautiful Confederation Bridge that spans the Northumberland Strait, linking Prince Edward Island with mainland New Brunswick. The 12.9 kilometer (8 mile) long multi-span post-tensioned concrete box girder structure took 5,000 laborers four years and $1.3 billion to build. The grand opening in 1997 was a Canadian national celebration.

The estimated lifespan of the bridge is 100 years or more. The rock-filled causeway that was originally proposed would not have lasted long in this passage. The Canadian Hydrographic Service estimates that tidal currents through a gap in such a causeway would be in excess of 18 knots (33.3 km/h/20.7 mph). That’s powerful enough to counter most commercial ships and sweep away house-sized boulders. The Northumberland Strait is also ruled by an extremely complex tidal regime. The tidal cycles on each side of such a causeway would be placed at opposites to each other.

The sheer size and weight of the components required strengthening the soil base at the staging facility. A crawler transport system was used to move pieces from fabrication to storage, and onto a nearby pier. The Danish-built heavy-lift catamaran, the HLV Svanen, was brought in to place the components in the Strait. What a sight that must have been. The Svanen was, and would still be, the tallest man-made structure on this windswept province.
