Route
The A4129 is a high-speed road between the two towns of Princes Risborough, Bucks, and Thame, Oxon.
The road begins at a roundabout in the centre of Princes Risborough outside the High Street and heads northwest, passing through the villages of Longwick and (after a long rural section) Kinsey. Other than that, it's a good example of an open road, provided you mind the humped bridge at the railway line!
At its western end, the road forms part of Thame bypass, leaving its original route between two roundabouts. The only other roundabout on the route is in Longwick, where the B4009 is crossed.
History
The bulk of the road was opened in 1826/7 as a mix of new build by the Risborough Turnpike and new enclosure road replacing the earlier route along the valley bottom. The A4129 was originally classified as part of the B4011. It was upgraded to Class I around 1930. The Thame bypass is the only change to the road's route since then.
