Over the past 5 years, Terra Nova National Park has been busy updating infrastructure and in some places building new assets. All of this work is being completed as part of the Federal Infrastructure Investment where Parks Canada will invest $3.0 billion to rehabilitate infrastructure assets within national historic sites, national parks, and national marine conservation areas across Canada.
In order to maintain our newly rehabilitated assets, Terra Nova National Park has committed to closely monitor infrastructure conditions. One way in which we do this is environmental monitoring.
Environmental Monitoring at the Eastport Causeway
Terra Nova National Park is located on the eastern coast of Newfoundland along several inlets of Bonavista Bay. Along the northern shoreline of the park, Highway 310 leads to the Eastport Peninsula acting as the only road access for the communities located there. The highway crosses Northeast Arm along the Eastport Causeway, a 1.25km rock fill structure.
In order to ensure the bridge remains in good condition, we are monitoring the environmental conditions surrounding it and making observations about how this will affect the life of this new asset.
The focus of this monitoring program along the Eastport Causeway is on the water level differential between Northeast Arm and Broad Cove, local weather conditions, wind generated waves and seasonal ice coverage.
Elements of the monitoring program include:
- A bottom mounted Acoustic Doppler Current Profiler (ADCP) installed offshore to measure wave action
- Two cameras mounted to individual steel masts to monitor wave action along the causeway
- A meteorological station with an additional camera and Two water-level loggers mounted to Broad Cove Bridge on an individual steel mast to measure weather parameters, wave action and water level differences
