The Hattieville - Boom Road, alternatively known as Burrell Boom Road or Route AR1-B, joins the Road 11 and Road 7 bypassing Settlement 37. It is approximately 12 miles (19 km) long.
In documents published by ECLAC in the 2000s, this route was previously identified as D200.[a]
The road was constructed in the 1950s as a gravel road, creating a crucial link between the George Price Highway and Philip Goldson Highway. In 2003 the current Burrell Boom Bridge was constructed to replace the old steel truss bridge and a bypass was built around Burrell Boom and the entire road paved. A 250m long floodway was also installed in 2003.[1]
Currently as of September 2025 a roundabout is under construction at the junction with the Philip Goldson Highway.[2]
