A number of specialists have been involved in the project, including Belinda Dechnik, who tests the water quality of the Clyde River as part of her role as environmental and sustainability graduate for John Holland.

"What we have to try and do is maintain it keep its natural baseline levels and make sure we're not polluting the river," she said.

"We also take water samples, measuring things such as chlorophyll, nitrogen and phosphorous, and just making sure we're keeping the marine park nice and healthy."

Senior project engineer Michael Mallett said part of the construction process involved a piling method - building foundations up to 30 metres under the ground to build from a hard rock material.

He said the method minimised the impact on the community, in terms of noise, and minimised impact on marine life.

Mr Mallett explains how the bored piling method works:

RMS project manager Kylie Curran said members of the community could drop in to the site compound to find out a bit more about the project.

"We're building more than just a bridge project here. We've got the new floating pontoon, we've got ramps for disability access onto the bridge," she said.

"We've got a beautiful new foreshore ... pedestrian (paths) and cycleways, as well as the beautiful new bridge.

"We've also been working with Foreshore Advisory Committee to make sure the community's views are heard in our new foreshore design."
