Переклад - Латинська-Французька - Romae vici angusti sunt,quod tabernae aut popinae...

Pont d'Aneta: "The streets of Rome are narrow, because the shops and joints/pubs occupy whole of them. Meanwhile Germanicus ordered to widen the streets."

Latin "At" I translated "meantime" as "just now", "in the very moment".
But another meaning is also possible here: "but" and it is very suitable here too.

Thanks a lot, my dearest.
