Does anyone know why it connects Sütlüce to Lapseke rather than Kilitbahir to Çanakkale further southwest along the Dardanelles? The gap looks about one third as wide there.

Perhaps most of the traffic will be coming from the northeast on the Europe side and the east on the Asia side, so Kilitbahir-Çanakkale would add an hour of driving for them? But if that's true, why didn't they built it at Gelibolu-Çardak, which naively looks like a similarly wide gap but would save half an hour?
