Crossings of the Forth estuary were, of course, undertaken by ferry for many centuries, until the first rail bridge was completed in 1890. But it would take a further seventy-four years before ANY road link was built.
In September 1964, therefore, the Forth Road Bridge was formally opened - by no lesser a celebrity than the Queen herself - to cater for a rapidly~increasing volume of traffic arising from motor vehicle ownership.
And so, on exactly the same date - 53 years later - she, our gracious Monarch will perform the official opening ceremony of this ... the third Queensferry Crossing!
Now there's a coincidence, if ever there was ... AMAZING,!
I must add, however, the bridge actually came into operation for traffic early yesterday morning.
