Trinity Bridge was designed by Spanish architect Santiago Calatrava, and was one of his earliest bridge works. The bridge has a typical Calatrava design utilising straight white lines as a structure, and is dominated by the rotund pylon which rises to 41m.[1] The bridge crosses the River Irwell, which marks the boundary between Manchester and Salford. The bridge was re-painted and examined in 2010 as part of the 15-year maintenance programme.[2]
