[8] In July 2017, in a bid to ease traffic congestion, the new Phnom Penh governor on Friday announced that Norodom Boulevard was one of the 11 main roads to be freed of vendors.

[9] Illegal parking and street vendors that encroach the pavements alongside Preah Norodom Boulevard between Wat Phnom and Independence Monument continue to cause serious disruptions because Preah Norodom Boulevard is the main road which national and international delegates travel on and its pavements are equipped with special luxury tiles for pedestrians and people with disabilities to use.

Line 2 runs southeast from the Chroy Changvar roundabout along France Street (47) towards Wat Phnom, turns onto Norodom Boulevard, continues to National Road 2, and stops at the base of the Takhmao bridge.

Line 3 runs south from the Russey Keo Garden Bus Terminal along National Road 5, onto Sisowath Quay, turns right on Street 106, left on Norodom Boulevard, right on Street 130 to Central Market, then takes Kampuchea Krom Street (128) west, onto Russian Federation Boulevard, turns left at the Chaom Chao roundabout onto National Road 3 and turns left towards the Borey Santepheap II Bus Terminal.
