Seymour Whyte was contracted by Transport for NSW’s Delivery Partner, Pacific Complete, to carry out three (3) concurrent, but separate packages of work:

  1. Main civil works (Section 3: Glenugie to Tyndale)
  2. Bridge structures (south package, Six Mile Lane to north of Chaffin Creek)
  3. Rigid pavement works (Sections 3: Glenugie to Tyndale; and Section 4: Tyndale to Maclean)

The main civil works component involved 2,240,950 m3 of earthworks (including 1,711,199 m3 of compacted fill), removal and remediation of haul roads, site accesses, hardstands, piling pads, and waterway crossings, realignment of local roads and traffic staging, construction of 4 new precast bridges and the new highway rest stop north of Bostock Road.

The rigid pavement package involved the construction of 45 km of rigid concrete pavement and 2 km of asphalt works between Glenugie and Maclean. This is one of the longest (45 km) and largest volumes (330,000 m3) ever constructed in Australia’s concrete paving history.

The bridge works involved the construction of 36 bridges (excluding piling and supply of precast concrete bridge component), associated civil works, traffic management and other necessary project and construction management works.

Some of the challenges successfully overcome by the team include: interface with multiple contractors given the alignment spanned great geographical distances.

The alignment was through several flood plains and low-lying rainforest areas, with soft soils sites requiring extensive monitoring and a well-thought-out planned approach to construction. The site also traversed through areas of cultural significance that belonged to four Aboriginal groups.

“…in regard to quality workmanship in field, Seymour Whyte has performed to a high standard and received complementary feedback for their paving works”
