Sir Leo Hielscher Bridge Tolling System Upgrade

As Principal Contractor for Transurban Queensland’s Roadside Tolling Upgrade Project, McIlwain recently managed the safe removal of the existing tolling structure located on the northbound Sir Leo Hielscher Bridge (Gateway Bridge).

The existing structure was replaced as part of the transition to a next generation tolling system which will be installed across the Gateway and Logan Motorways.


The northbound Sir Leo Hielscher Bridge is the first of 13 sites to be upgraded as part of the project. Since July 2017 McIlwain has been preparing each site along the Gateway and Logan Motorways including the installation of new concrete footings and barriers to form a solid foundation for the new gantry structures.
The removal of the existing structure took place on Thursday 11 January 2018 followed by the installation of the new girder on Friday 12 January 2018. A 350t crane was positioned on the motorway which lifted the structures to and from a holding area on Administration Drive. During the overnight construction works, multiple lane and on-ramp closures were implemented prior to a four hour bridge closure between 10pm and 2am, to ensure the works were safely and efficiently delivered with minimal impact to motorists.
McIlwain’s Project Manager Paul Robson said, “The construction works were completed ahead of schedule and without any issues. The planning and execution of the work is a direct reflection of the dedication and professionalism all parties involved.”
Transurban Queensland Project Manager Naomi Peters said, “The Sir Leo Hielscher Bridges are integral to vehicle movements throughout South-East Queensland. Transurban Queensland needed to partner with an organisation that would fully appreciate the importance of this and work with us to ensure the works were completed safely whilst minimising the impact to our customers. Thanks to the diligence and commitment of McIlwain, all construction works were completed safely and ahead of schedule”.
McIlwain will complete the Roadside Tolling Upgrade Project at the remaining 13 locations along the Gateway and Logan Motorways by late 2018.
