Small hump-backed footbridge over 'the chasm' (name derived from Douglas Hague reference), built to connect the Skerries Lighthouse with beacons and landing-points on the east of the Skerries islet. The bridge is built of mortared quarry stone, with traces of limewash and a cobbled path. It is reached via a series of rock-cut steps and a concreted path across uneven rocks from the south-west.
