If Sher Shah Suri was the one who really built Grand Trunk Road, why does Megasthenes mention an 1800 KM Grand Trunk Road connecting Hindukush to Bihar 1800 years before Sher Shah Suri? https://t.co/63BIwRtJDl

Thanks to Greeks who left many historical accounts of ancient India. Otherwise, everything would have been credited to a Sher Shah Suri or another Afghan invader

This mention of 10,000 stadia=(c.1800 KM) royal road connecting Hindukush to Pataliputra comes from "Indica" pic.twitter.com/L0r6LDHCby
