A network of infrastructure was built into the landscape for the Games to integrate a new parkland into the fabric of the city. Much of it is in use today, as it contributes to the post-Games legacy.

The legacy of the 2012 Olympics was designed to be embedded in the city and to ensure that as much of the financial investment in the Games as possible would go towards creating enduring benefits for the whole of east London. As part of this, a network of new infrastructure was built into the landscape, to integrate a new parkland into the fabric of the city. Much of it is in use today, as it contributes to the post-Games legacy.

The size of the park and the diverging needs created a significant challenge. It required an infrastructure solution that satisfied both the temporary needs - to allow the millions of visitors during the Games to access and cross the park, and the permanent - for those connections to work for generations to come as part of the Legacy Masterplan.

Allies and Morrison designed thirteen permanent bridges which formed a family with common geometries, details and components, and a further fifteen temporary bridges, designed as overlay elements, were removed after the Games to reveal a pre-formed river valley of landscaped terraces. Maximum investment was made in the permanent structures while temporary installations were designed in an economic and sustainable way that would allow ease of removal and re-use wherever possible.

The permanent bridges are embedded within the landscape, and designed simply to extend the concourse across the water. This strategy allowed other bridges, particularly those at the park's perimeter, to adopt bespoke forms responding to their contexts, and thus constitute an essential component of the public realm. Among the most significant is the northern access bridge, connecting the North Park over the Eastway to Eton Manor; its bold red-orange colour highlights the sculptural quality of its elements and allows it to stand out as a marker as a northern entrance to the park.
