Further pictures today showing the construction of the M27 in 1974 as it cut a chalk swathe through Paulsgrove and what would become North Harbour.
We can see looking east with Southampton Road on the left of the frame and the houses with the lengthy gardens which stretched down to the old northern limit of Portsmouth Harbour before the land was reclaimed.
Those homes were demolished and replaced by the giant North Harbour Tesco.
And bottom right shows the future North Harbour taking shape.
The IBM building is under construction while the old Johnson & Johnson roundabout, half-way along Southampton Road, can be seen clearly.
On the right is the loop which would eventually bring traffic from Paulsgrove and Western Road on to the M27.
