As Lee said the reason for the covering is protection from the weather-Keep the main structure dry and it will last for ages. Replacing the cladding is a much easier task than replacing the main structure.It is especially important to protect the end grain to stop water being drawn into the timber-hence fence posts often have caps on them.
The timber arches appear to be mechanically laminated using bolts, a practice still used today for most timber footbridges in the UK and probably elsewhere, although the bolts are replaced by 32mm steel dowels that you cannot see.
I applaud our American cousins for their wide use of timber for all forms of structure-too many in the UK think timber either burns or rots.
