The historic causeway to Hayling Island known as the Wadeway still exists, however it is now completely impassable, having been cut in two by a deep channel for the Portsmouth and Chichester Canal in the 1820s, the same company having subsequently funded the old wooden road bridge, served by a toll-house situated at the northern end.

The much earlier causeway was known as the Wade Way,[1] and was classified as a bridleway in 1988, and is shown as such on modern Ordnance Survey maps[2] in spite of its use being considered hazardous at best.

[3] Excavation of this feature in 2006, constructed on a natural high point in the harbour, put its date in the Roman to mediaeval range but found no evidence to be more specific.

[citation needed] Houses in the terrace on Langstone High Street date back to the 18th century and a number are thatched.

The other significant buildings, commonly featured in local postcards, is Langstone Towers, characterised by a large lightning conductor.
