Esk–Hampton Road

The Esk–Hampton Road is a state highway in Queensland. It leaves the Brisbane Valley Highway at Esk and travels in a westerly direction for 45.7 km until it reaches the New England Highway at Hampton, where it ends. This road is part of State Route 85, which extends for over 570 km from Bribie Island to Nindigully, duplexing with the Brisbane Valley Highway (National Route 17) from the D'Aguilar Highway to Esk, the New England Highway (State Route A3) from Hampton to Toowoomba, the Gore Highway (National Route A39 - formerly 85) from Toowoomba to the Leichhardt Highway, and the southern 19 km section of the Leichhardt Highway (also National Route A39) to Goondiwindi.

Esk–Hampton Road is a state-controlled district road (number 414), rated as a local road of regional significance (LRRS).

History
From a historical perspective the Esk–Hampton Road consists of three sections of approximately equal length.

The eastern section, from Esk to the foothills of the Great Dividing Range, was developed along Redbank Creek (the watercourse) to provide access to stands of timber, and to a sawmill that was located at Redbank Creek (the locality). Subsequently, it serviced farms that were established on land cleared of most old-growth forest.

The western section, from Hampton to the end of a spur of the Great Dividing Range, was also developed to facilitate the harvesting of timber. Prior to European settlement the rich volcanic soil on the ridge supported a sub-tropical rainforest, which contained timbers that were in high demand, including red cedar, tallowwood and hoop pine. These timbers were used in some homes constructed in the area at the time. The road later provided access to cleared land that was used for dairying and beef cattle grazing. This section provides access to Ravensbourne National Park, which preserves a remnant of the rainforest.

The central (mountain) section was developed later, to enable more direct travel between the two districts. The road is now a popular tourist drive, particularly as part of a round trip from the Brisbane area to the Toowoomba district. It is rated as a "good ride" by motorcycling tourists.

The mountain section was completed in 1929. One of the most difficult sections to complete was the Pryde's Pinch section which had a steep gradient and was not suitable for traffic until sometime after 1932.
