Another evening of modelling, and I’ve started to add detail in between the cross members of the viaduct.

Only the channels at the outside bottom of the bridge are continuous pieces. The pieces of channel that represent the other longditudinal channels are formed from cut sections. These are measured out with a caliper.

Here one of the first cut pieces of channel is fitted to the inside of the viaduct.

Some more cross members are glued to the base channel and cut pieces of channel fitted between them.

The sections that make up the inside bottom channels vary in length, depending on how the different cross members are arranged.

At the end of the evening this is how the viaduct looks. At first glance it doesn’t look a lot, but quite a lot of detail has been added.
