Monorail Track Re-Born To Help Build North West Rail Link

Member for Baulkham Hills David Elliott today announced the former Sydney Monorail will help build Sydney’s rail future – in an innovative solution to reduce community impacts from construction of the $8.3 billion North West Rail Link.

 “Sydney’s transport past is helping build our public transport future as we get on with the job of delivering Australia’s largest public transport project,” Mr Elliott said.

 Mr Elliott said 60 steel beams removed from the monorail last year have been refurbished and will soon be used to build a temporary road bridge at the site of the new Norwest station.

 “This temporary bridge is an innovative solution which dramatically cuts the length of time a key local road has to be closed – from up to three years to around four months,” Mr Elliott said.

 “A great hallmark of this project has been talking to the community and coming up with solutions to their concerns – this is another example of listening and acting.

 “Following feedback from the community and local businesses, we’ve had another look and come up with an innovative solution that will minimise road closures while keeping the North West Rail Link construction schedule on track.”

 Original plans proposed a lengthy closure of Brookhollow Ave at the intersection of Norwest Boulevard so the underground railway station could be built.

 Now, a temporary bridge will be built at road level and the road then re-opened to traffic – while the excavation of the new station continues under the bridge, dramatically reducing disruptions above ground.

 Brookhollow Ave will only need to be closed for about four months for the bridge to be built, with the road closure starting on February 7.

 “When the bridge solution came up, we looked around for the steel needed to build it and found that the Sydney Monorail was being demolished at the same time – so we said, ‘we’ll take that’,” said Terry Sleiman, the project director for tunnelling consortium Thiess John Holland Dragados.

 The monorail beams have been welded and refurbished to make 29 bridge girders, weighing between 11 and 17 tonnes each and spanning more than 32 metres in length.

 They will form the main structural part of the temporary bridge and will be lifted into place by a 200 tonne crane during the next two months, over a five- night period.

 Benefits of using the monorail beams include less concrete needed for the bridge deck while the time needed to demolish the temporary bridge will be cut by half, reducing noise and other impact on the community.

 The nearby community and businesses have been notified about the closure of Brookhollow Ave and will be kept fully informed during work over coming months.
