The City of Perth is hoping the saying actions speak louder than words will help convince the Government to adopt the council's preferred light-rail route.
The council will put scale-sized replica tram carriages - 2.5m wide and 43m long - in Hay Street mall today to show businesses, residents and shoppers just how disruptive a light-rail route through the pedestrian mall could be.
A final decision is yet to be made on the exact route of the proposed $1.8 billion Metro Area Express project connecting Mirrabooka and the city, but the Hay Street mall is the State Government's preferred option for the CBD section.
Perth Lord Mayor Lisa Scaffidi said installing light rail through a pedestrian mall was illogical and argued a route down William Street and St Georges Terrace was better.
"Once our pedestrian malls are lost, they will be lost for ever," she said.
"People need to see the impact for themselves."Route options exist that do not destroy city amenity, so why would they not be the obvious and preferred choices?"
