Making 30 km access road accessible for all concerned.
The Government of Newfoundland & Labrador's Department of Transportation had numerous obstacles to overcome when faced with the challenge of designing a 30 kilometer access road to connect the town of St. Lewis with the Trans Labrador Highway. In the first km outside the town, the access road would need to go right through the salt water of Fox Harbour. Since the harbour is sensitive to the Atlantic salmon, there was a need for a stream crossing to allow the salmon to travel upstream for spawning during the summer months.
Corrosion-resistance a big plus.
Paul Whittle, P.Eng., the design engineer for the Department of Transportation, decided to use a 5.0 m diameter Dur•A•Span™ pipe for this application. The Dur•A•Span™ pipe takes care of a number of challenges that face all applications of saltwater installations, including corrosion.
Time was of the essence at installation.
Bonne Bay Contractors of Rocky Harbour, NL were awarded the contract to build the St. Lewis access road and in the summer of 2000, the Aluminum Structural Plate Pipe was installed in the dry, within a few days of assembly. With little time to spare, Gerald Budgen, President of Bonne Bay Contractors, focused all of his resources on backfilling both sides of the pipe. By the next day, the pipe was completely backfilled prior to the tide rising.
Today, the local residents, tourists and marine life enjoy the access that was created or maintained.
