Hi ljones56,

Unless something has changed, Carfax has a No Entry sign for southbound traffic (except cycles): https://www.mapillary.com/app/?pKey=131534852351315&focus=photo&lat=51.062524961300284&lng=-0.3281082310751344&z=16.852768485179972&x=0.47516744226960833&y=0.5942209067282249&zoom=2.5686695278969953

And I believe East Street also has a No Entry sign going east from Market Square. Are you sure these aren't one way?
