The A2046 was a short A-road in Portsmouth.
The road started on the A3 between the Guildhall and Portsmouth & Southsea station. It headed east along Greetham Street before zigzagging left into Victoria Road North to meet the A2047 by Fratton station. The road continued along Goldsmith Avenue into Milton where it ended on the A288 by the park.
By the 1970s the road had gained the A2046 number although this did not last long. Winston Churchill Avenue was later constructed as a city centre relief road and this, together with Goldsmith Avenue, became an extension of the A2030. It is possible that the A2046 number had already disappeared when this took place.
