About

The Swan Street Bridge project involves the upgrade of one of Melbourne’s iconic bridges and surrounding infrastructure, in the heart of Melbourne’s premium sporting and event venues. The bridge provides access to and from the CBD for around 30,000 vehicles per day, as well as thousands of pedestrians, cyclists, trail users, rowers, and commercial and private boaties along the Yarra River.

The complex project involves widening the bridge from four to five lanes, demolishing and replacing the existing outer beams on the northern and southern side of the bridge, and tying back into the existing structure. The project also incorporates twin 4-metre-wide cantilevered walkways on either side of the new bridge structure, upgrade to the east and west abutments, and an additional traffic lane along Olympic Boulevard and Alexandra Avenue.

During construction, significant challenges were faced and overcome, such as impeding river traffic, relocation of a critical gas main prior to demolition, re-design and installation of curved custom-made precast beams, restrictions on existing structure load capacity, geometry of cantilevered footpath connections, tight construction tolerances and complexities in the reinforcement design.

In conjunction with Major Road Projects Victoria (MRPV) and the City of Melbourne, the project solution achieved a finished product with high focus on architectural finishes, consistent with the iconic location of the bridge.

“Seymour Whyte demonstrated innovation in its construction techniques and openly collaborated with MRPV to ensure the quality of construction was respectful to the iconic bridge and reinforced its place in Melbourne…the team executed the works to a very high quality in an incredibly complex environment.”

Damien Afxentis, Program Director, MRPV.
