EastLink is a tolled section of the M3 freeway linking a large area through the eastern and south-eastern suburbs of Melbourne, Australia. It is a part of Melbourne's Metropolitan Ring Road project. EastLink is electronically tolled with no cash booths, using a system developed by SICE. The SICE Tolling System is similar to (and interoperable with) the e-TAG system used on the CityLink tollway. EastLink was opened to traffic on Sunday 29 June 2008 and in conjunction with the opening, a month-long toll-free period occurred before regular tolling commenced on 27 July 2008. The project was constructed by a joint venture of Australian construction companies Thiess and John Holland, with tolling system contracted to SICE, and mechanical and electrical work contracted to United Group Infrastructure. The final project cost was A$2.5 billion. Signs are at the entrances and on the tollway direct to Ringwood, Dandenong, Frankston and Doncaster.
