|Route outline (key)|
The second incarnation of the B2125 was used for a short link in Lancing, Sussex, existing from around 1926 (when the road was first classified) to around 1933. Like its predecessor, it was upgraded to Class I, becoming the A2025 which it remains.
Starting on the A259 coast road the B2125 headed north along South Street before bearing left by the church to cross the railway line by Lancing station; the A2025 now bypasses this section. It then detoured via Grinstead Avenue to rejoin the present main road before following Grinstead Lane to its terminus on the A27.
