If you’re planning on getting out and about on Sydney’s roads this Sunday, take heed: many of our streets, highways and expressways will be closed for the Blackmores Sydney Running Festival. More than 35,000 runners are expected to lace up their sneaks for the multi-race event, which includes a marathon, half marathon, 10-kilometre bridge run and 3.5-kilometre fun run.

Road closures will be in place from 4am to 1.30pm along the course, which begins at Milsons Point, traverses the Sydney Harbour Bridge and finishes at either the Opera House or the Royal Botanic Gardens (depending on the race). The bridge and Cahill Expressway will be closed from 4am until 11am, but the Sydney Harbour Tunnel will remain open. Also closed between 4am and 11am will be a number of streets around Milsons Point, as well as Oxford and Flinders Streets in Darlinghurst.

From 4am to 11.30am major streets including George Street, Hunter Street and Macquarie Street will be closed, with the section of Macquarie Street north of Bridge Street shut down until midday. All city-bound traffic on the Anzac Bridge will be diverted into the city via the Bathurst Street off-ramp from 4am, and there will be no direct access between the Anzac and Harbour bridges until 12pm.

A number of streets in Pyrmont will be closed from 4am until 12.30pm, while some sections of Hickson Road in The Rocks, Millers Point and Barangaroo will be blocked off until 1.30pm. Roads around Moore Park will be blocked off from 5.30am to 11am, and access to the Entertainment Quarter via Anzac Parade will be closed off. Centennial Park will be off limits to all vehicles and cyclists from 4am until 11am.

Runners are encouraged to catch public transport to and from the event – it’s free if you show your chest bib. The closest train station to the start line is Milsons Point, and Circular Quay is your best bet once you’ve finished.
