The national highway that will connect Corinth and Patras in the Peloponnese will be completed by the end of 2015, according to Greek national broadcaster NERIT. In the spring of 2015, the first 30 kilometers will be ready for use. The highway will be named Olympia Road and will enable drivers to go from Corinth to Patras in 50 minutes. Taking the existing highway, drivers can cover the distance in 65-70 minutes. The total distance of the new highway is 201.5 kilometers and the Elefsina-Corinth part is already completed. Olympia Road has 14 tunnels covering a total of 16 kilometers, with the longest tunnel being 4,033 meters. According to NERIT, a new toll booth will be added in Nikoleika of Aigio, making a total of three toll booths between Corinth and Patras; Kiato and Rio are the other two. Engineers consider the particular road construction one of the most difficult in Greece since 85% of the road is in use during construction works. The Corinth-Patras part is 120 kilometers and currently there are 20 construction zones, employing 220 workers.
