The £1m project was more than two decades in the making.
Five years ago, to mark the road’s 40th anniversary, we trawled our archives to put together a timeline of its development – going as far back as the 1950s.
Here, we present a gallery of photographs from its opening day (plus a handful of bonus, related pictures).

The Botolph Street junction. In January 1977, residents in Botolph Street spoke out over disruption caused by the construction of the inner relief road.“It’s dreadful trying to live here while all the work is going on. You can’t keep carpets clean because the street is so muddy,” said one. Photo: Boston Standard
