The maximum length of a pilot is 65 metres. Sixteen pilots have been envisaged and installed per one pier. A cathode protection Construction is proceeding well has been carried out for the anti-corrosive protection of steel pilots. The construction project of the west branch of the Istrian Epsilon on the section Reinforced concrete piers of maximum heights of up to 40 metres were carried out in of the Adriatic motorway A9 from the Umag interchange to the Medaki (Vrsar) slipform in three metre long segments. Steel span frameworks were carried out on the interchange will be built in its first phase in semi-motorway standard. Works in right and left side on prepared plateaus behind the supports. The span framework was the 1B phase are divided into three sub-phases and include: joined in the middle by a system of pushing from both sides of the bridge.
