Bill Dargue states that the turnpike was set up from Birmingham along the Lichfield Road as far as Watford Gap in 1807.
For reference, the OS Map of 1887/8 shows the end of Corporation Street, then Aston Street to Gosta Green, It then becomes Aston Road until Aston Brook Street, where it becomes Aston Road North until Aston Cross. From Aston Cross it becomes Lichfield Road.
In 1834 the Aston Brook Mill comes up to Let. I think it would be at Aston/Hockley Brook near the present Aston Brook Street. It is advertised as on Lichfield Road. So maybe the toll gate would be nearer to Birmingham than the Vine?
It may also be that, in the earlier days, the road from the Toll Gate towards Lichfield would be more well-known as “the Lichfield Road.”
In the book History of Birmingham, by Hutton 1835 he says....“The roads to Lichfield and Coleshill, now Aston and Coleshill Streets, extending to Duke Street, the boundary of the manor.”
So Aston Street is quite old, and as the manor boundary was Gosta Green maybe the toll gate was somewhere around this street?
