Madam, – John Stafford’s suggestion of an elevated Ha’penny Bridge has much to commend it (February 5th). Wouldn’t it be the case, however, that pedestrians on an elevated bridge would run the risk of being decapitated when the long-awaited Liffey cable car is up and running? It would be a shame also if the East meets West project were to be thwarted by a scheme to facilitate Northsiders finding their way home safely from Temple Bar. – Yours, etc,
