|Route outline (key)|
The road starts at traffic lights on the Norwich outer ring road, where the A140 TOTSOs to take up the western side of the ring road. The A146 runs along the southern section via a couple of roundabouts to another set of lights where it TOTSOs right; the ring road ahead is now the A1054.
Now dual carriageway, the A146 goes over the railway line and the River Yare to reach a signalised diamond GSJ with the A47 southern bypass. There is another set of traffic lights just afterwards, which is where the old road from the city centre comes in from the left; to the right is the B1332 (former A144).
The A146 continues southeastwards across arable farmland. There are a few buildings on this section but the first village, Thurton, is not met for some distance. Shortly afterwards the road bears onto a bypass - and remains on a newer alignment for much of the remainder of its route. Chedgrave and Loddon are bypassed, after which the old alignment is reached again, although this has been improved. A roundabout is then reached where we join the A143 and a multiplex, where the road's original route leaves us again.
Despite the fact that the A146's route is straight ahead and the A143 has to zigzag here it is the latter number that is dominant. The multiplex lasts until the next roundabout at Gillingham (pronounced with a hard G). The A146 then enters the Norfolk Broads National Park and crosses the wide River Waveney into Suffolk. It bypasses Beccles to the north; the A145 into the town is met at a roundabout, after which the Lowestoft to Ipswich railway line is crossed at a level crossing.
The A146 now leaves the national park and rejoins its original route at a roundabout at Worlingham. It loops to the south to reach North Cove before moving north again to run parallel to the railway line for a short distance. The road goes past a golf course before reaching the suburbs of Lowestoft. At a roundabout the A1145 bears off to the right; this is the way to go to reach the southbound A12. The A146 continues ahead along a surprisingly rural road in the circumstances: there are fields to the left and the houses to the right are largely inaccessible from the A146. Presently, however, the road does become urban. It soon reaches traffic lights and ends here at a TOTSO on the A1117. Until the 21st century the A146 continued ahead to end on the A12 to the south of Lowestoft town centre but that road is now a short section of A1117 as far as the next roundabout and the B1531 thereafter.
In February 2017, Norfolk County Council announced that it would invest £1.63m into adding a roundabout to the Hales T-Junction where the A146 meets the B1136 that runs between Haddiscoe and Hales as a short cut between the A146 and A143. The current T-Junction would be replaced with a 3 exit roundabout in order to lower the high accident record that this junction has. The work is due to start in the early part of 2018.
