On this motorway within a built-up area, what is the maximum speed you may travel at if there is no signage?

The speed on motorways and dual carriageways within built-up areas may be increased through the use of the corresponding signage, without in any case exceeding the generic limits established for such roads outside built-up areas. In the absence of signage, the maximum speed that vehicles must not exceed on motorways and dual carriageways within built-up areas is 80 km/h.
