Main Roads Western Australia controls the major roads in the state's Kimberley region. Great Northern Highway is the major road connection through the region, with sealed roads spurring off it to connect to population centres, and unsealed roads offering an alternative route between Derby and Wyndham. The region's main roads are important to the Kimberley, as roads are the only transportation mode within the region. Great Northern Highway is the only sealed road linking the region to the rest of the state, and via Victoria Highway, the rest of the country; therefore, it is particularly important for defence, freight, and tourism. Freight needs include transportation of minerals to the ports at Derby and Wyndham for the mining industry, cattle to ports or abattoirs, and produce to markets (including to the Wyndham port for export) for the agricultural industry based around the Ord River Irrigation Scheme area. Broome Highway Broome Highway, also known as Broome Road, is a major road in the Kimberley region of Western Australia. It connects Great Northern Highway in Roebuck to the coastal town of Broome. Derby Highway Derby Highway is a major road in the Kimberley region of Western Australia. From Great Northern Highway in Willare, it travels north to the western end of Gibb River Road, and then on to Derby. Gibb River Road Gibb River Road, also known as Derby Gibb River Road and Gibb River Wyndham Road, is a major north-east to south-west road in the Kimberley region of Western Australia. The road offers a more direct route between Derby and Great Northern Highway south of Wyndham than travelling on the highway itself, but is an unsealed gravel road except for short sections at either end. The road is often closed due to flooding during the wet season, which is typically November through March, although delayed openings have been known to happen, frustrating the tourism industry. Great Northern Highway Great Northern Highway is a main highway through the Kimberley region, and part of the Perth to Darwin national highway. From the south-western edge of the region at Eighty Mile Beach near the Sandfire Roadhouse, the highway travels north-east along the coast to Roebuck, east of Broome. From here it heads east to the Willare Bridge Roadhouse at the Fitzroy River, south of Derby. The highway continues east to Fitzroy Crossing, where it crosses the Fitzroy River a second time. It continues east, curving
