A commemorative ICE 125 plaque has been installed at the bridge, in celebration of the 125 years since the Institution was established in the region.
ICE North East members were asked to vote for the projects they believe have had a positive impact on the region, based on their engineering technical excellence, public benefit, sustainability and influence on raising the profile of civil engineering.
Gateshead Millennium Bridge, along with Tees Barrage, were unanimously selected as the top two projects by ICE North East, as part of its prestigious Robert Stephenson Awards, which recognise engineering excellence across the region.
Penny Marshall, ICE Regional Director in the North East, said: "It is an important period in the Institution's rich history as we gear up for our bicentenary, and it is equally important to recognise the impact key landmarks have had on the North East. There are many projects and structures throughout the region that have contributed a great to deal to the region's infrastructure and people's everyday lives in the region.
"The Gateshead Millennium Bridge is an iconic structure that has benefited the Newcastle-Gateshead quayside economy immensely, and has become a symbol of Tyneside. It was resoundingly selected as one of the region's top infrastructure projects by our members, as a result of its importance to the region and the wider North East economy."
Cllr Angela Douglas, Cabinet Member for Culture Sport and Leisure at Gateshead Council, said: "The Gateshead Millennium Bridge is now a distinctive part of the Tyneside skyline and we're very proud that it's been unanimously chosen by the Institution as one of the most important engineering projects in the North East over the last 125 years."
