The Sultan Qaboos Street forms the main artery of Muscat, running west-to-east through the city. The street eventually becomes Al Nahdah Street near Al Wattayah. Several inter-city roads such as Nizwa Road and Al Amrat Road, intersect with Al Sultan Qaboos Road (in Rusail and Ruwi, respectively). Muttrah, with the Muscat Harbour, Corniche, and Mina Qaboos, is located in the north-eastern coastline of the city, adjacent to the Gulf of Oman. Other coastal districts of Muscat include Darsait, Mina Al Fahal, Ras Al Hamar, Al Qurum Heights, Al Khuwair, and Al Seeb. Residential and commercial districts further inland include Al Hamriyah, Al Wadi Al Kabir, Ruwi, Al Wattayah, Madinat Qaboos, Al Azaiba and Al Ghubra.
