1910: World’s longest reinforced concrete bridge

Worlds longest reinforced concrete bridge, Mizen Head

The fog signal station on Mizen Head is reached by a spectacular footbridge that is an engineering gem. An early example of reinforced concrete construction, it is 52m long and was the longest of its time and possibly the first to use precast elements.

Everything was cast on-site using sand crushed from local rock. The narrow bridge crosses a steep gorge and for 80 years all the station’s supplies were ferried across, often in wheelbarrows. The bridge was rebuilt in 2011. The station was automated in 1993 and is now a visitor centre at Ireland’s most south-westerly point.
