The Greek privatisation agency opened a tender procedure for a concession to run Egnatia Odos; a motorway running from west to east, in northern Greece.
The contract is part of a privatisation process launched by Greece under a multi-billion euro bailout accord with international lenders.
Authorities said the award of the services concession contract for the financing, operation, maintenance and commercial exploitation of Egnatia Odos and three annex roads to the Preferred Investor, is for a maximum period of up to 40 years.
The tender process will be conducted in two phases, comprised of pre-qualification and a binding offers phase. The expression of interest must be submitted by Jan. 26, 2018, privatisation agency HRADF said.
Egnatia Odos is a 658 km (409 miles) long highway, stretching from the western port town of Igoumenitsa to Evros in the east, at the border with Turkey.
