About

​TNE Civil has been engaged in the Stephenson Avenue Extension Project since April 2023 contributing to several key infrastructure components as part of the project's goal to provide a new connection from Cedric Street to Scarborough. We have delivered Bridge 1418 over Stephenson Avenue and the substructure for the Intermittent Launch Bridge 1400 over the Mitchell Freeway. TNE have also completed a Pedestrian Underpass to improve accessibility and safety and are constructing 500m+ of Retaining Walls for new Freeway on-ramps, complemented by a Hybrid Precast-Insitu Road Barriers to ensure driver safety and enhance traffic flow as vehicles merge onto the freeway. Our responsibilities also extend to executing Drainage and FRP works for the Water Corporation.
