The Centenary Bridge Upgrade is one of Brisbane’s most significant infrastructure developments in recent years. Designed to improve traffic flow, boost road safety, and future-proof one of the city’s busiest river crossings, the project involves building a new three-lane northbound bridge and carrying out remediation works on the existing bridges over the Brisbane River.
At the heart of the early construction phase, KPI Construction Services played a pivotal role by delivering specialist Traffic Management Services — ensuring the safe movement of road users while enabling construction crews to work efficiently.
Overview of the Centenary Bridge Upgrade
Project Scope and Objectives
The upgrade involves:
-
Constructing a new three-lane northbound bridge alongside the existing Centenary Bridge.
-
Repairing and upgrading the existing northbound and southbound bridges to meet modern safety and structural standards.
-
Enhancing active transport facilities for cyclists and pedestrians.
Key Stakeholders and Project Partners
The project is overseen by the Queensland Department of Transport and Main Roads (TMR), in partnership with leading civil engineering contractors. KPI Construction Services worked closely with these stakeholders to integrate traffic management seamlessly into the broader project delivery plan.
The Importance of the Upgrade for Brisbane
Traffic Congestion Challenges on the Centenary Motorway
The Centenary Bridge is a crucial link between Brisbane’s western suburbs and the CBD. Over the years, traffic volumes have grown significantly, leading to bottlenecks, delays, and reduced travel reliability.
Safety Improvements for Motorists, Cyclists, and Pedestrians
By widening capacity and upgrading structural safety, the project will reduce collision risks, improve emergency response times, and offer safer pathways for non-motorised road users.
KPI Construction Services’ Involvement
Traffic Management Services Provided
KPI Construction Services was engaged during the early works phase to:
-
Design and implement traffic control plans in compliance with Queensland regulations.
-
Coordinate with construction teams to allow uninterrupted site operations.
-
Safeguard both workers and the travelling public.
Planning and Coordination with Project Teams
The KPI team worked closely with engineers and site supervisors to develop staged traffic diversions that maintained traffic flow while enabling safe work zones.
On-Site Implementation and Monitoring
Traffic controllers managed lane closures, detours, and speed restrictions, adapting in real time to site changes or unexpected events.
Community and Stakeholder Communication
Public notices, detour maps, and clear on-site signage helped residents and commuters stay informed, minimising frustration and confusion.
Managing Early-Stage Works on a Live Traffic Corridor
Minimising Disruption During Peak Hours
The Centenary Motorway is one of Brisbane’s busiest routes, so KPI scheduled high-impact works during off-peak periods and at night to avoid significant traffic delays.
Adapting to Unforeseen Site Conditions
Unexpected weather and traffic incidents required rapid re-planning, with KPI teams ready to adjust traffic setups instantly for safety and continuity.
