JC Butko Engineering personnel joined the team that put the shared cyclist/pedestrian crossing in place overnight on Saturday as part of Transport for NSW's Newcastle Inner City Bypass Project.

The 34 metre structure had been manufactured in Wodonga and transported north last week.

JC Butko Engineering senior project manager Shane Giddens said the road had been shut about 9pm, the bridge was "basically in" at 2am and the JC Butko Engineering workers had left the site by 4am.

"A lift like that generally goes fairly quick, it's the planning that takes the longest period of time," he said.

Borger Cranes supplied the 400 tonne crane that lifted the bridge onto its piers.

"It had to be millimetre perfect so it was a big relief," Mr Giddens said.

"With all the planning that you do, it's always pleasing when something like that drops directly into position."

The bridge, which crosses over Newcastle Road, is not yet open to the public.

Its construction is early work for the 3.4 kilometre Rankin Park to Jesmond section that will complete the north-south connection of the main bypass.
