The English is clear enough to lorry drivers - but the Welsh reads "I am not in the office at the moment. Send any work to be translated."
When officials asked for the Welsh translation of a road sign, they thought the reply was what they needed.
Unfortunately, the e-mail response to Swansea council said in Welsh: "I am not in the office at the moment. Send any work to be translated".
So that was what went up under the English version which barred lorries from a road near a supermarket.
