- 4 - 29 April 2014

Summary of Progress

We have also:

•Completed both tunnel breakthroughs.

•Conducted a landscaping trial at Fill 31 (at Ewingsdale, north

of the tunnel portal).

•Made preparations for the tunnel lining.

- 5 - 29 April 2014

Roadworks

Progression of earthworks activities:

• Large excavators, dozers and scrapers will be used less

and less.

• We’ll move into sub-pavement activities; and

• Then conclude with detail earthworks activities.

How will this look?

- 6 - 29 April 2014

Roadworks

Bulk Earthworks – mass movement of earthen material in cut-fill operations

- 7 - 29 April 2014

Roadworks

Sub-pavement – detail placement and trimming operations of

layers that support the roadway.

North and Southbound carriageways immediately to the south of Ivy Lane on 5 April 2014

- 8 - 29 April 2014

Roadworks

Detail earthworks and finishing – boxing-out, backing-up,

median and verge and topsoil spreading activities.

- 9 - 29 April 2014

Roadworks

Expectations over the next three months:

• Larger excavators, dozers, dumpers and scrapers will

be demobilised, but smaller equipment will remain.

• Rock hammering, processing and crushing will diminish.

• Sub-pavement and detail activities will increase.

Generally, this transition will be more noticeable from the

southern end of the project moving towards the north.

- 10 - 29 April 2014

Roadworks

Crushing

We are anticipating that all crushing operations should finish by August. Crushers are currently located at and should be completed by:

•Cut 20, about 2kms south of Bangalow Road - mid-June.

•Cut 28 near the Southern Portal - late June.

•Cut 30 just north of the Northern Portal - late May, but then mobilising to Cut 31, ½ km north until early July.

- 11 - 29 April 2014

Bridges

Progression of structural activities:

• Sub-structure works - abutments, pilecaps and piers are almost

done.

• Activities associated with the super-structure are now key; and

• Then we’ll conclude with bridge furniture and the off-structure

works.

How does this look?

- 12 - 29 April 2014

Sub-structure works – those elements which support the

bridge such as the pilecaps, piers, headstocks and abutments.

Northern end of Bangalow Road and Tinderbox Creek bridges both looking southwards on 5 April 2014

Bridges

- 13 - 29 April 2014

Super-structure works – the installation of girders and decks

that form the bridge.

Bridges

- 14 - 29 April 2014

Decking and off-structure works including furniture - the

items that permit the bridge to be safely and functionally

utilised.

Precast concrete parapets; end posts; abutment backfill at Broken Head Road bridge.

Bridges

- 15 - 29 April 2014

Bridges

Expectations for the next three months:

• Installation of girders at:

• Skinners Creek, occurring now.

• Watsons Lane, as soon as weather permits.

• Tinderbox Creek, throughout May.

• Bangalow Road, out of hours works in early June.

As soon as Byron Creek northbound is open for construction

vehicles (hopefully in the next week) this will reduce

construction traffic on Tinderbox Road.

- 16 - 29 April 2014

Paving

Expectations for the next three months:

• Start of sub-base paving in the southern zone during May.

• Continuation of hand pours at Ewingsdale roundabout.

• First hand pours at Bangalow interchange in July.

• Some mainline paving north of the tunnel to facilitate traffic

staging.

- 17 - 29 April 2014

Paving

Our paving strategy is essentially to do as long as runs as possible in each production day through each of the zones in succession, broadly:

• Southwards from Ivy Lane, turn around then all the way back to Minor Creek, turn around and complete the southern loop.

• Southwards from Bangalow Road, turn around at Emigrant Creek, then all the way back to the tunnel, turn around and complete the central loop.

• Northwards from the tunnel, turn around and then complete the northern loop.

- 18 - 29 April 2014

Traffic

Key activities that have affected the travelling public:

• Once Byron Creek northbound is open to construction traffic in

late April (hopefully this week) truck movements on Tinderbox

Road will reduce significantly.

• Truck numbers have declined from a peak of about 140 pre-Xmas

to around 90 now, we expect that number to diminish

significantly through May / June.

• Our girder deliveries will conclude with Bangalow Road

in early June.

How does this look?

- 19 - 29 April 2014

Traffic

Key activities which will effect the travelling public:

• Cement tankers and quarry trucks will continue to deliver to our

batch plant for the duration of the paving.

• Concrete agitators will supply the tunnel – peaking during the

tunnel lining from May to September – as well as the bridges.

• We anticipate being able to run paving supply along the project

alignment from August, this is contingent upon the

Emigrant Creek traffic diversion.

- 20 - 29 April 2014

Traffic

Staging and sequencing of traffic:

• 2nd stage of traffic diversion at the Ewingsdale roundabout

in late May.

• Diverting the Pacific Highway southbound traffic on to

Woodford Lane for the Byron Bay exit in early June.

• Pacific Highway traffic beneath the north most span of

Emigrant Creek bridge in late July / early August.

• 1st stage of traffic diversion at the Bangalow roundabout in July.

- 21 - 29 April 2014

• Both tunnel breakthroughs achieved: southbound on January

24 and northbound on February 24.

• Controlled tunnel blasting is complete.

• Excavation continues for several more weeks.

• Tunnel control centre concrete tank construction ongoing.

• Tunnel concrete lining works ie, waterproofing, steel fixing,

concreting have started.

• Southern portal cut and cover preparations underway.

Out of Hours Work

Expectations over the next three months:

•Detail kerb removal near the Myocum Road roundabout.

•Girder installation at Bangalow Road in early June.

•Saw cutting once base paving starts from Ivy Lane in July.

•Tunnel lining continues.

- 27 - 29 April 2014

Bangalow Interchange

•Construction of the Bangalow interchange has started and will

take about ten months.

•Concrete paving will start on the southern half of the new

interchange at Bangalow Road in July.

•Out of hours concrete saw cutting will be required and directly

affected residents will be advised in advance.

•Once pavement and road furniture are complete on the

southern portion, Bangalow Road will be diverted to that side.

•The same process will then occur for the northern portion.

Bangalow Road overbridges

New Bangalow Road bridge

•Girder installation is scheduled for early June and will require

nightly closures of Bangalow Road.

•Eastbound traffic out of Bangalow will need to use the Pacific

Highway to go to Byron Bay / Suffolk Park; no issues for

Ballina bound traffic.

•Westbound traffic into Bangalow from Byron Bay / Suffolk

Park will need to use St Helena Road or Coopers Shoot Road.

Remaining Pacific Highway bridge over Bangalow Road

•Demolition of old northbound Pacific Highway at Bangalow

Road will occur towards the end of the project.
