Traffic delays on Mulgrave Road: Why Cairns residents should pay attention

Residents of Cairns have experienced increasing delays on Mulgrave Road, a key arterial route leading into the city. Recent roadworks, combined with higher traffic volumes during peak hours, have seen average commute times extend by up to 15 minutes for drivers traveling between Earlville and Cairns CBD.

Understanding the reasons behind these disruptions is critical as Cairns continues to grow both in population and tourism. Traffic flow affects access to essential services, local businesses, and overall quality of life. The increase in vehicles on roads like Mulgrave Road reflects broader challenges facing Cairns regarding transport infrastructure and urban planning.

Local Impact: Commuters and Businesses Feel the Strain

Mulgrave Road serves as the main connector not only to Cairns CBD but also links suburbs such as Earlville, White Rock, and beyond to the city. Peak-hour traffic congestion has grown steadily according to the Cairns Regional Council. Local businesses along Mulgrave Road and adjacent Stanley Street report concerns about reduced customer footfall due to construction delays and detours.

The Cairns Chamber of Commerce has highlighted that these traffic disruptions are particularly impactful for small enterprises reliant on timely deliveries and customer access, including supply chains servicing the hospitality sector near the Cairns Esplanade. Similarly, residents living in Earlville and White Rock have expressed frustration over longer school runs and delayed public transport options, including bus routes operated by Sunbus.

Data Points Reflect Growing Transportation Pressures

Cairns Regional Council data shows that Mulgrave Road now handles approximately 35,000 vehicles daily, a 12% increase over the past three years. The ongoing roadworks, scheduled through to October 2026, aim to widen lanes and improve drainage to enhance resilience against seasonal cyclones. However, these improvements come at the cost of reduced road capacity during construction periods, directly contributing to congestion.

Public transport usage in the Cairns region has also plateaued, with only 18% of daily commuters using buses as of the 2025 transport survey by the Department of Transport and Main Roads. This reliance on private vehicles further intensifies traffic density. Additionally, fuel cost increases, with petrol prices averaging $1.82 per litre in Cairns this month, add financial strain on residents coping with longer travel times.

Future plans include the Cairns Regional Council's proposed 2027 public transport enhancement program, which aims to increase bus frequency along key routes including Mulgrave Road. Improvements to cycling infrastructure on Sheridan Street and in the nearby CBD precinct are also in the works to encourage alternative, sustainable transport modes.

Residents and commuters are advised to plan journeys outside of peak morning and afternoon hours where possible, use real-time traffic apps like Google Maps or Waze to avoid bottlenecks, and consider trialing public transport options promoted through the Citytrain initiative. Monitoring council updates on roadwork schedules will help minimize unexpected delays.

Ultimately, the traffic challenges on Mulgrave Road and surrounding areas underscore the need for continued investment in Cairns' transport network to support the region's growth while protecting the livability cherished by local communities.
