Motorway

668 km-long dual carriageway across northern Greece forming part of Trans European Roadway and including 70 tunnels, mainly in the Pindos mountains in a variety of rock mass conditions ranging from massive limestones and sandstones to clay schists. Design and construction responsibility lies with Egnatia Odos AE, a company set up by the Greek government. Brown & Root, project managers; construction managers for the three sections are: Sogelerg/Omec/Lahmeyer; De Leuw Cather; Egnaconsult/Dorsconsult/Scetauroute/ADO. Completion for 2001. Will be hugely picturesque. March 1999.   Joint venture of Sarantopoulos, Attikat, J & P and Teck awarded contract to build Polymilos-Lefkopetra section of motorway with nine tunnels. November 1999.   Greek jv Aktor SA has placed a $12 million order on Sandvik Tamrock Corporation for 24 units of drillrigs, loaders and trucks to be used mainly on the Egnatia highway. Visit www.sandviktamrock.comAktor reports progress at three sites, all of which involve twin-tube highway tunnels of up to 110 sq m excavated section, sometimes with 65 sq m top heading in advance. Excavation and support is varied according to ever-changing ground conditions, but always includes grouted rebar bolts, steel arches and shotcrete. 4.6 km-long Driskos and 3.3 km-long Dodoni are at elevation 850 m asl in the Pindos mountains near Ioannina at the western end of the Egnatia highway, and Veria is in the central section where three short tunnel of lengths 1 km, 200 m and 300 m are under construction. Driskos has advanced 180 m on each face from the south portals without incident and work is starting to establish the north portals using extensive forepoling. At Dodoni work is from the east portals where the right hand tube has advanced 170 m. The left hand tube is at a standstill at 70 m while a 1,000 cu m cavity formed by running ground is stabilised by pressure grouting using a Haeny ZMP 710E pump. At Veria, the left hand tube from the south portal of the first tunnel has advanced a cautious 40 m in 60% phyllite which disintegrates on contact with water. Putzmeister shotcrete jumbos are in use at all sites.
