The A46 Bypass round Lincoln is an abysmal road; I too use it very frequently.
you will be aware that it is not yet complete as a bypass, much of it (close to the A15) is single carriageway and, (during the periods 7am-9am and 3pm-5:30pm) is nothing short of a standstill at times. The A15 is generally straight, but bad in summer for farm vehicles, lorries and general slower moving traffic. It also has many dips and inclines. It is known as a major death road as people overtake and take risks here. It was so bad that my wife and I moved away from Lincoln in terms of our work so we wouldn't be using the road. Winter further amplified the nightmare.
Enough of the RAC Lesson
