The 30-tonne steel structure is part of the £66m-plus Exhibition Centre Liverpool and associated four-star Pullman hotel development on the city’s waterfront and marks a milestone in Liverpool's aim to become a major international events destination.
The design and build scheme started on site in January this year, with the Exhibition Centre Liverpool due to open in September 2015.
The bridge will be clad in glass, creating a new landmark for Liverpool that references the site’s industrial past and enhances the views across the waterfront, a Unesco World Heritage site.
Bob Prattey, chief executive of ACC Liverpool, said: "The pedestrian bridge symbolises the next stage in the continuing success of ACC Liverpool as we join our existing building with an ambitious new facility."
Mayor of Liverpool Joe Anderson added: "The exhibition centre will be a massive boost for Liverpool’s economy, attracting huge numbers of visitors and supporting many jobs. I am delighted that the work is on track and we have passed this major milestone in creating a fantastic new facility for the city."
C&IT recently featured ACC Liverpool's director of sales Kerrin MacPhie in The Social Network, which revealed her love of events and a hatred of Westlife.
