Swan River Pedestrian Bridge, Perth, Australia


Swan River

A new pedestrian bridge over the Swan River in Perth, Western Australia, is being constructed to connect East Perth with the Perth Stadium and Sports Precinct on the Burswood Peninsula.

The bridge will connect the Perth Stadium with public transport and car parks in East Perth, as well as the central business district (CBD).

Construction on the bridge was initiated in late 2015 and is expected to be completed by early 2017. The bridge is being constructed as part of the Perth Stadium project and is being managed by Main Roads WA on behalf of the Western Australian State Government.

When the Perth Stadium opens in early 2018, the new bridge is expected to be used by approximately 14,000 people on event days.

The expression of interest (EOI) to design and construct the pedestrian bridge was initiated by the Western Australian State Government in February 2014.

Design and features of the Swan River Pedestrian Bridge

The Swan River Pedestrian Bridge will stretch 400m from bank-to-bank. It will have a width of at least 9m, and a steel cable-stay span of 160m at the centre.

The bridge will have a centre structural arch, an apex rising 65m above the river.

It will feature two piers driven into the river bed to reduce the impact on the river, as well on two piers on either shore. It will have a 40m-wide vessel navigational area with a clearance of 8m between the water and the bridge deck.

The design also includes two landscape pause points and decorative lighting across the bridge.

Swan River Pedestrian Bridge construction details

Construction on the pedestrian bridge began in late November 2015. The site office for the construction supervision was built in the same month.

The initial in-river works included the installation of silt curtains and clean granite to construct a 100m temporary causeway.

The construction will cover approaches at both ends of the bridge, as well as bus stands on the East Perth foreshore and full landscaping on both foreshores.

The steel and concrete for the cable-stayed bridge will be assembled on the Burswood Peninsula side, while a smaller work area is in operation for construction activity in East Perth.

After completion, the structural steel bridge will be covered with Teflon-coated fabric. It is estimated that approximately 1,500t of steel, 1.6km of piles, and 1.5km of steel cables and strip lighting will be used in the construction.

Construction of the first causeway on the Burswood Peninsula commenced in January 2016, followed by the second in East Perth in March 2016. A total of 48 piles have been installed on both sides of the bridge.

"It is estimated that approximately 1,500t of steel, 1.6km of piles, and 1.5km of steel cables and strip lighting will be used in the construction."

When the bridge foundations are complete, preparatory works for the arches will begin. The bridge arches and deck are expected to be installed in mid-to-late 2016.

The bridge construction is expected to be completed by early 2017.

Contractors involved with the construction of the Swan River Pedestrian Bridge

A contract worth $54m to design and construct the bridge was awarded to a joint venture of Rizanni de Eccher and York Civil in June 2015.

Mott MacDonald was selected by the joint venture (JV) to verify the design of the structural, waterway and drainage elements of the bridge in October 2015.

Enigma was awarded a contract to design the deck and arches in March 2016.
