West out of King William Street at No. 32 and south to 137 Upper Thames Street (P.O. Directory). In Candlewick, Bridge Within and Dowgate Wards.
Formed in accordance with an Act of Parliament of 1829 to provide for the formation of approaches to the New London Bridge. The street was cut through Miles' Lane and St. Martin's Lane, and completely absorbed the southern end of St. Martin's Lane.
It was originally called Arthur Street West to distinguish it from the eastern arm leading into King William Street from Monument Square, but when this eastern portion was finally absorbed in Monument Street in 1911, the necessity for the distinctive suffix passed away and the street is now called "Arthur Street " only.
