The Enugu-Port Harcourt Expressway was constructed in the late seventies during the Nigerian military regime.

It is a significant southeast road that connects at least five states in the Eastern area, including Enugu, Anambra, Abia, Imo, and Rivers.

The administration of President Goodluck Jonathan awarded the contract in September 2013 to Messrs Arab Contractors Nig.
