After a second discussion we have decided to just build our focal section of the bridge that will be spray painted in realistic colours. Judging by the size of the model we will be able to include lots of detail on the support beam and under structure to this section of walkway, which should be visible in the reflection from the backsprayed acrylic representing the water. One potential issue of making this section is that the cables coming out of the support beam will be cut off halfway in midair with no further walkway to support. This means we will have to ensure we attach them into the triangular points along the beam securely enough so that they are held in place at the correct angle.
We have trialed acrylic and matal wire for the railings around the base. Looking at what has been working we believe we need to purchase a thinner acrylic tube to heat bend for the curved sides of the walkway along with much finer acrylic rods for the curved railings.
