Here's a press cutting showing the newly opened Pack Saddle bypass, I think from 1957. The road at that time was the B479, later redesignated A4074, known locally as the 13 bends of death on account of the large number of accidents on the stretch from the Pack Saddle to Cane End.
There are 3 pubs alongside the A4074 in the area, Pack Saddle, Pack Horse and the Fox at Cane End, though the latter is now an indian restaurant. People couldn't remember which order they stood in on the road out of Reading, so a local saying was devised- you put the saddle on the horse to chase the fox!
I believe there is now a small garden centre attached to the Pack Saddle.
