The Luas light rail bridge in Dundrum, Dublin, named after William Dargan, a famous railway engineer.
The M1 road bridge over the Malahide Estuary, on a particularly greyly grim day. I like the shadows.
A very foolish person crouches at the edge of the Cliffs of Moher, Co. Clare, Ireland. Many people die each year doing things like this, caught by sudden gusts of wind, and shortly after this photo was taken, it was made more difficult to access the edge. The cliffs themselves are a persistent tourist draw, and it is said they have featured in numerous films, including The Princess Bride.
