Butterfly Bridge, Piccadily, Manchester. Opened in 2006.

            CTS was appointed to design, manufacture and install an attractive bespoke footbridge in the busy and restricted city centre location of Piccadilly, Manchester.

Installation appropriate to the inner city location was the governing parameter in the bridge’s design; resulting in a tied arch solution. The constrained site, over a busy road and adjacent to a train line, required a simple, single lift for safe and fast night installation.

Due to the width of the completed structure, transportation as a fully assembled form was not possible and the inner city location could not provide a vacant plot for a ground level assembly area.

Solution
From the initial architectural concept drawings, CTS developed the bridge design to maintain both aesthetic intent and buildability.

The striking design was drawn in a Tekla 3D computer package to enable precision fabrication of the complex geometry.

The soffit of the deck, which was suspended from a tied arch with cables, incorporating feature openings to allow light to spill onto the street below. Lighting was incorporated into the landmark scheme to provide interest and security.

To overcome the transportation challenge, CTS used the roof of the adjacent building as the assembly area to fabricate the elements into the final bridge superstructure.

Outcome
The resulting structure demonstrated clean lines and elegant detailing to ensure a successful landmark footbridge.
