The Gateway Motorway and Gateway Extension extends 48 kilometres from the M2 Logan Motorway in Drewvale, near Browns Plains to the Gympie Arterial Road M3 in Bald Hills. The Sir Leo Hielscher Bridges (formerly the Gateway Bridge) are part of the Gateway Motorway. Originally opened in 1986 the Gateway was widened between 1991 and 1995.

In 2010 the Gateway Motorway was upgraded as part of the Gateway Upgrade Project that included new Intelligent Transport Systems (ITS) and electrical assets. The contract had a 10-year maintenance phase due for handover in 2020.

Jerana was engaged by Gateway Motorway Services (the Maintenance Operator) to prepare a report for the ITS and electrical assets along the Gateway Motorway franchised area known as Gateway Motorway Nudgee to Eight Mile Plains. Jerana established the project contract conditions and maintenance operator scope to expand methods for assessment of electrical assets. The outcome of the report was RPEQ certification to support assessment of residual design life based on asset data, compliance, and visual inspections.
