From the Oxford English Dictionary: “An elevated structure, consisting of a series of arches or spans, by means of which a railway or road is carried over a valley, road, river, or marshy low-lying ground.”
When we visited the Blue Mountains we went for a ride on the Zig Zag Railway; a narrow gauge railway located 10 km east of Lithgow, at Clarence. When the railway was built there were only three materials for bridges which were needed to negotiate the mountainous gradients. Timber – quick to build but short lived because it was vulnerable to termites and rotting; iron – long lasting but expensive as it had to be imported from UK, and took months to arrive; and sandstone, long lasting, but expensive unless locally available which it is in the Blue Mountains.the Zig Zag Railway. The train chugged and puffed over three wonderful sandstone viaducts and through two hand-hewn tunnels plus a cutting. The views over the surrounding countryside are stunning.
For this challenge, interpret the theme “bridge.” You can go the same route as I did and capture any type or style of bridge where you are, or go deeper and take a snapshot of something or someone that acts as a bridge in your life: a link, a connection, a mediator.
