It runs through the village of Radko Dimitrievo, crosses the river Golyama Kamchiya and enters the Smyadovo Field. After passing east of the town of Smyadovo the road enters the Veselinovo Gorge of the river Brestova reka, a right tributary of the Golyama Kamchiya. It exits the gorge at the village of Veselinovo[2] and reaches the eastern part of the Rish Valley. There, it turns west and in 8km again heads south and begins to ascend the northern slopes of the Varbitsa Mountain, part of the eastern Balkan Mountains, through the Rish Pass (410m), and enters Burgas Province.
The II-73 descends along the southern slopes of the mountain, crosses the river Luda Kamchiya and reaches the village of Prilep.
