The humble Lego block - a staple in children's toy collections around the world - took on a slightly more serious role in Perth over the long weekend as adult enthusiasts used the iconic building blocks in a bid to break a world record.
The 39m-long suspension bridge is set to feature a 19m free-span section - 5m longer than the record-holding Lego bridge built by German enthusiasts.
Members of the Perth Adult Lego Society spent 2500 hours building the bridge.
The world record bid is part of this year's Model Railway Exhibition at Claremont Showground.
The exhibition was billed as the biggest yet by the WA branch of the Australian Model Railway Association, with more than 45 exhibits and 21 retailers.
The fundraising event is open today, with paid entry between 9.30am and 4pm.
