The bridges
Upstream view in the Akcay tunnel. The entrance of this tunnel is visible from the Yüksekkemer
bridge, but it can be entered east of the Akçay bridge. The tunnel can be followed for 300 m.
Visible are three vertical building shafts, course corrections where tunnel segments met and
sections where the roof had to be strengthened with concrete, and where remains of formwork are
clearly visible. Note the bat (middle right)
