Initially constructed in 1962 as the Dubreuilville Industrial Road, Highway 519 was assumed by the province in 1985-1986.

From there it travels 30.4 km (18.9 mi) eastward through a hilly and heavily forested region.

[4] The highway ends at Green Lake Road, just before entering Dubreuilville, a village built to service the Dubreuil Brothers lumber operations in the surrounding boreal forest.

Gravel-surfaced over its entire length at the time of designation, paving of the highway began in 1986 and was complete by 1987.
