1868 – Obelisk Bridge, Oldbridge, Co. Louth
Erected to replace a wooden bridge which collapsed in 1867. Heavy piers of limestone at either end are united by two wrought-iron double latticed iron sides. Responsibility for the design shared by John Neville (Co. Surveyor for Co. Louth), Samuel Searancke (Co. Surveyor for Co. Meath) and Alexander Tate, civil engineer. The Boyne is the border between the two counties. Only Neville’s name appears on plaque on bridge.
