And it is better to leave it as "I-2" instead the wrong "Blvd.Vladislav Varnenchik". It is not Vladialav Varnenchik.

Because this is the real name (identification, ID) of the road. Blvd.Vladislav Varnenchik starts at the point, where the motorway A2 overs - in the beginning of Varna and pass through the city till the center (to the Cathedral). I just clean the confusion.
