from february 2017, the a12 no longer reaches norfolk as it terminates in lowestoft. before february 2017, from a point just south west of the mouth of the river yare, northwards to the point where it crosses the river yare in great yarmouth, the a12 followed the route originally used by the railway line from lowestoft to its terminus north of breydon bridge at vauxhall roundabout where the a47 previously terminated.
