Project Overview
The Legacy Way tunnel project is a 4.6-kilometer underground motorway in Brisbane, Australia. It was built to connect the Western Freeway to the Inner City Bypass, thereby providing a direct link between the western suburbs and the city center.
The tunnel was designed to alleviate traffic congestion on the existing road network and to improve travel times for motorists. It was also built to support the growth of the western suburbs and to provide a more efficient and reliable transport corridor for the region.
Key Features
- 4.6-kilometer underground motorway
- Connects the Western Freeway to the Inner City Bypass
- Alleviates traffic congestion
- Improves travel times for motorists
- Supports the growth of the western suburbs
- Provides a more efficient and reliable transport corridor
Design and Construction
The Legacy Way tunnel was designed with several key features to ensure its safety and efficiency. The tunnel’s alignment was carefully chosen to minimize disruption to existing infrastructure and to provide a direct route between the Inner City Bypass and the Western Freeway.
The tunnel’s cross-section is a twin-tube design, with each tube accommodating two lanes of traffic. The tubes are separated by a central wall, and the entire tunnel is enclosed in a concrete shell. This design provides a high level of safety and protection for motorists.
Ventilation System
The tunnel’s ventilation system is designed to maintain a safe and comfortable environment for motorists. The system uses a combination of natural and mechanical ventilation to remove pollutants and provide fresh air. Natural ventilation is provided by vents located at the tunnel’s entrances and exits, while mechanical ventilation is provided by fans located throughout the tunnel.
Construction Methods
The Legacy Way tunnel was constructed using a variety of methods, including the cut-and-cover method, the immersed tube method, and the bored tunnel method.
The cut-and-cover method was used to construct the tunnel’s approaches. In this method, a trench is excavated, the tunnel is built within the trench, and the trench is then backfilled.
The immersed tube method was used to construct the tunnel’s underwater section. In this method, prefabricated tunnel sections are floated into place and then sunk into a trench.
The bored tunnel method was used to construct the tunnel’s underground section. In this method, a tunnel boring machine (TBM) is used to excavate the tunnel through the rock.
Unique Challenges and Innovations
The construction of the Legacy Way tunnel presented a number of unique challenges, including the need to excavate the tunnel through challenging geological conditions. The TBM used to excavate the tunnel was equipped with a special cutterhead that was able to cut through the hard rock.
Another challenge was the need to construct the tunnel under an existing railway line. To avoid disrupting the railway line, the TBM was used to excavate the tunnel at a depth of 30 meters below the railway line.
