CONSTRUCTION OF ROADSIDE INFORMATION BAYS


ROAD SAFETY AND INFRASTRUCTURE

CONSTRUCTION OF SEALED INFORMATION BAY AT MATARANKA

The construction of the sealed Information Bay area along the Stuart Highway successfully enhanced the safety and functionality of the roadway in Mataranka. The primary objective was to develop an access road, deceleration lane, and turning lane, alongside the construction of two information bay structures. This project significantly improved traffic flow and provided travelers with a designated space to stop for information, ultimately enhancing road safety.

The works involved minimal clearing of vegetation, followed by leveling the site to maintain natural drainage and crossfall. A select fill subgrade layer was placed, and a compacted base course gravel layer was installed to support the traffic load adequately. The design ensured that the finished surfaces prevented water ponding and provided a durable access point to the Information Bay.

Additionally, the project widened the existing highway to create a deceleration lane and a left-turning lane, improving vehicle movement and safety at the junction. New table drains were installed to efficiently divert water away from the road surface, reducing the risk of erosion and ensuring the longevity of the infrastructure.

By employing robust civil engineering practices and adhering to environmental management requirements, the project not only addressed immediate roadway needs but also enhanced the resilience of the area against future environmental challenges. The successful completion of this project resulted in a safer and more efficient roadway for all users, reflecting modern standards for infrastructure development in the Northern Territory.
