Designing and manufacturing high-quality modular expansion joints to stringent standards always requires skill, experience and great attention to detail, but when one of New York’s most famous – and busiest – bridges needed a unique solution to be developed to overcome the challenges of replacing its existing joints, then a special kind of competence was demanded. Fortunately, mageba’s team in New York has extensive experience in overcoming such challenges for New York landmarks such as the Verrazzano Narrows Bridge, the Tappan Zee Bridge, the Bayonne Bridge and the George Washington Bridge.
The Queensboro Bridge has connected the New York City boroughs of Manhattan and Queens across the East River since 1909. When the bridge required its expansion joints to be replaced, mageba was selected to design and fabricate the joints and supervise their installation. Fourteen TENSA®MODULAR expansion joints with up to eight movement gaps were needed – and the ten joints of the main steelwork structure had to be supplied with pre-integrated bridge deck panels.
Thanks to the mageba team’s close collaboration with the client’s engineers, a solution was developed that minimized impacts on the bridge and on traffic during the expansion joints’ recent installation – and the Queensboro Bridge joins the impressive list of New York landmarks that rely on mageba key components every day.
