text:  Because he reigned only briefly , Nerva 's public works were few , instead completing projects which had been initiated under Flavian rule . This included extensive repairs to the Roman road system and the expansion of the aqueducts . The latter program was headed by the former consul Sextus Julius Frontinus , who helped to put an end to abuses and later published a significant work on Rome 's water supply , De <unk> Urbis <unk> . The only major landmarks constructed under Nerva were a granary , known as the <unk> <unk> , and a small Imperial Forum begun by Domitian , which linked the Forum of Augustus to the Temple of Peace . Little remains , partly because the Via dei <unk> <unk> cuts across it .
