| A12 road
Bury St Edmunds
For much of the route (between Yarmouth and Bury St Edmunds) the road is classified as a primary route. Over the years the road has been much improved with new by-passes opening at regular intervals. The last of these being the Broome - Ellingham bypass in March 2002.
Great Yarmouth to A146
The A143 begins as an off slip from the A12, just south of Great Yarmouth. The road continues in a south-westerly direction. On leaving Yarmouth there is a very short section of dual carriageway and from there the road is a strictly rural affair and there are not many straight sections.
This part of the route runs through some lovely countryside and passes many local attractions along the way. These include Fritton Lake, Caldecotte Hall and Redwings horse sanctuary. The route passes through the villages of St Olaves and Haddiscoe before joining up, for about 1 mile, with the A146 at a roundabout a few miles from Beccles. During the summer months this is an area very popular with holiday makers so the road can be quite busy at times.
A143 to Diss
The road in this area has undergone major changes in the last few decades. The original route took you through the centre of many towns and villages and has now been renumbered the B1062. From the Suffolk town of Bungay until Harleston the road follows the route of the now defunct Waveney Valley Line railway and progress along this section of the road is generally quite good as there are no reduced speed limits, save for Brockdish. The road eventually intersects with the A140 Norwich to Ipswich road, just outside the Norfolk town of Diss.
Diss to Bury St Edmunds
Once the road leaves Diss it returns to an older route. This takes it through a number of villages on the way to Bury including Great Barton, where there has long been a campaign for a bypass. Along this section the road crosses the A1088 Thetford to Woolpit road at Ixworth. The A1088 joins the A14 at Woolpit.
Bury St Edmunds to Haverhill
On arrival in Bury the road travels underneath the A14 and at this point the route is no longer considered primary and now becomes an ordinary A road. It then continues to wind through some nice Suffolk countryside until it links up with the A1307 at Haverhill. From here it is only a short distance to the M11 which gives easy access southwards to London and north to Cambridge.
The road has been criticised for its road safety record, especially in Suffolk, where the road has been described as consistently one of the most dangerous roads in the county.
Along the route of the A143 you pass next to or very near to a number of railway stations.
