B3800 Selly Oak – Selly Oak

The B3800 is very short link road in Birmingham, cutting a corner between Harborne Lane and Bristol Road by using Chapel Lane.

It was created in 2021 as part of the Selly Oak Triangle works. With A38 being diverted away from Selly Oak centre along the new Aston Webb Boulevard and taking over part of A4040 along Harborne Lane, including dualling this section up to the Great Oak junction, this left Chapel Lane, which had formerly taken A4040 anticlockwise traffic up to Bristol Road looking redundant. However, it still serves Battery Park, a retail park on its northern side, and is to provide access to the new development on the site of the former Sainsbury's supermarket in the centre of the Triangle. So it was deemed worthy of a Class II number, and given where it is, this should have been one beginning with "4". But as with B384, the former A38 through Selly Oak, Birmingham City Council have decided that they know better, and have given it the out-of-zone number B3800, making it (as of the time of writing) the highest-numbered B-road starting with "3".


The road is straight, with a flat junction with Harborne Lane at the bottom, a roundabout managing access to Battery Park about halfway along, and a a light-controlled junction with Bristol Road at the top. It should also be noted that the road belongs to that exclusive group of numbered roads where it's possible to see one end from the other.


As detailed above, it was formerly part of A4040, which at that time was designated Birmingham's Outer Ring Road, a designation no longer in use though the road continues to form a complete circle of Birmingham, but until the "creation" of the ORR by erection of numerous signs, the section from Harborne to Cotteridge, including the stretch through Selly Oak, was part of A4123.
