Fans heading to the Optus Stadium tonight for Fremantle’s clash against Adelaide are being warned to leave plenty of time for their journey, with peak-hour traffic expected to affect travel.

The Fremantle Dockers will host the Crows in yet another prime-time blockbuster at Optus Stadium, with bouncedown at 6.10pm and gates opening at 4.30pm.

Ahead of the match, Main Roads WA is urging footy fans to plan ahead and leave early.

A Main Roads spokesperson said: “Allow for extra travel time as heading to the game coincides with afternoon peak.

“Expect extra congestion on Graham Farmer Freeway, the tunnel eastbound and the CBD from 4pm.

“Expect heavy foot traffic and frequently stopping vehicles in the area.”

Attendees are urged to catch a train or bus to the game, with public transport included with tickets.

Drivers are also reminded to check signs for tow away zones before parking around the stadium.
