THE Pacific Highway Sapphire to Woolgoolga upgrade took another giant leap forward this week.
Northern beaches commuters were excited to see the bridge beams installed over the Headlands Rd overpass at Moonee Beach.
Seven Super-T girders were installed at the site, which means the overpass now spans the full width of the upgrade site.
Each weighs more than 42 tonne and the overpass has a total of 12.
"Work on the Pacific Highway Sapphire to Woolgoolga upgrade is progressing well," a Roads and Maritime Services spokesperson said.
"In the last six weeks 186 of the total 586 bridge beams required have been installed."
Remaining work on the 60 metre long Moonee Beach overpass bridge includes the installation of safety screens and handrails on the eastern deck.
There are 28 bridges and two underpasses being built as part of the Pacific Highway Sapphire to Woolgoolga upgrade.
Bridges nearing completion include Greys Road, Newmans Road underpass, the Woolgoolga Creek twin bridges and Cunninghams Creek.
During the next two months, there will be continuing earthworks and drainage, bridge work and the building of concrete and flexible pavements.
There will also be controlled blasting about two kilometres northwest of Woolgoolga and the demolition of the existing overpass on Diamond Head Dr, Sandy Beach.
