History
Pastoral leases were taken up in the Fraser Coast Region from 1843, and European settlement of what is now Gympie began soon after. The Gympie district was part of the large Widgee Widgee pastoral area. In 1887, 43,000 acres of land were resumed from the Widgee Widgee pastoral run for the establishment of small farms. Further south, 21,760 acres were resumed from Imbil. The land was offered for selection on 17 April 1887. The opening of new farms on the western side of the Mary River to the south of Gympie led to the development of roads in the Mary Valley.

A pastoral lease was taken up as Kenilworth Station in 1850. The effects of the 1884 Land Act reached the Kenilworth area in 1888, when land on grazing properties was surveyed and made available for selection. Development of small farms in the Imbil and Kenilworth areas led to the need for a road to transport products to Gympie, and also requests for a railway line. The road was completed quickly, but a railway did not arrive until 1914-15. Meanwhile, further road improvements had been undertaken.

Upgrades
A project to design active transport crossings, at a cost of $1.3 million, was to be completed in July 2022.
