Bulgarian and Turkish NGs at the Canakkale bridge (joint NG site visit)


During 7-9 October 2021, the Turkish and the Bulgarian Groups of IABSE came together for a site-visit to the Canakkale bridge in Turkey. Chaired by Alp Canar (Turkish NG, Chair) and Marina Traykova (Bulgarian NG, Chair), during this successful and very interesting site visit, the participants had the opportunity to see and learn from this unique construction site. This event, after a long lockdown, also helped in establishing a close professional contact between these two neighbouring National Groups.
