This article is about the former A5207 west of Aintree. For the original and still extant A5207 in Kirkby, see A5207.
Northern Perimeter Road
The A5207 was a short link road in south Lancashire which has been renumbered several times. Originally the western end of the B5194, the road became the A5276 in the late 1970s and was then upgraded to become the A5207, a number that already existed further east. When the parallel A5758 was opened further north in 2015 the road was downgraded again and is now numbered B5207, a number that also exists elsewhere.
Starting on the A5036 west of Old Road station the A5207 started heading west but then bore round to the right to run alongside the A-road as far as Switch Island, although it did not link to that junction. From here our road bore left to run along the northern edge of Netherton, as evidenced in its name of Northern Perimeter Road. After going over the B5422 at traffic lights the road crossed the fields to reach Thornton, where it ended on the A565.
