Expressions of interest have been invited by 1 March for the estimated $1,000 million Izmit bay crossing. The client is the State Highways Directorate (KGM – see Tenders). The consultant for the build-operate-transfer (BOT) scheme is a venture of Canada’s Delcan and the local DAP (MEED 3:12:93).

The crossing will run from a point near Gebze, on the Istanbul to Ankara motorway, to Orhangazi, outside Bursa, a length of about 50 kilometres. The bay crossing itself will be a bridge, or a combination of bridges, about 3.5 kilometres long, with approach viaducts of two to three kilometres on either side.

The KGM expects to draw up a shortlist from the expressions of interest. However, there is some debate among contractors and consultants about the possibility of operating a BOT system over the whole route, and whether sufficient revenues can be generated from tolls under a private-sector franchise to pay for construction costs.
