The proposed Conveyor Bridge

The following is an extract from the Evening News, April 3, 1903:

The proposed Hayling Island Aerial Bridge

1903 proposal for a Conveyor Bridge to link Portsmouth to Hayling Island across the harbour entrance

1903 proposal for a Conveyor Bridge to link Portsmouth to Hayling Island across the harbour entrance

Today we are enabled to give an illustration of the Traveller Suspension Bridge which it is proposed to construct across the Langstone Harbour channel to Hayling Island. The bridge is a portion of an important scheme for the development of the island which has accorded the hearty approval of a large and influential meeting of landowners and residents held at the Royal Hotel, Hayling on Tuesday.

The bridge will have a span of 720 feet from tower to tower, and along the steel girders a traveller car will run from side to side. The dimensions of the car will be 50 ft in length and about 30 or 35 ft wide, and it will be capable of carrying an electric car and about three or four carriages, besides pedestrians and cyclists up to about 60 tons in weight. While should it be required for ferrying troops across this stretch of Langstone Harbour, up 5000 could be conveyed from one side to the other in the course of an hour.

The illustration shows the level of the water at low ordinary spring tide, when the distance from the girder would be 103 ft 6 ins, and at high tide when the distance would be 90 ft. The lower part od the car would be a distance of 15 ft above the high water level, and 28 ft above low water. The elevation of the bridge it is estimated would be quite high enough to allow merchant shipping passing underneath.

Mr G.E. Eady M.I.C.E of 53 Victoria Street, Westminster and Mr Cobbett M.I.C.E. of Fareham, are the engineers of the scheme, and are confident of the ultimate success of the undertaking. Similar bridges have been or are being constructedover the Usk at Newport (Mon), across the Mersey at Runcorn, and over the Ribble between Southport and Lytham, whilst others are at Rouen over the Seine and at Bilbao, Spain have given every satisfaction. Everything is to be worked by electrical power.

Several gave evidence as to the necessity for the bridge and the great advantage of linking Hayling and Portsmouth. The cost was estimated at about £63,000. The bridge would be built sufficiently strong to be safe in a gale of 80 miles an hour without any stress and it would stand in a storm up to 160 miles an hour wind velocity.
