Peacocke Bridge is a girder bridge under construction over the Waikato River in Hamilton, New Zealand. The bridge on Wairere Drive is part of the Southern Links, which will complete a ring road around Hamilton. It will link Hamilton East with a new suburb of Peacocke. Construction started in 2020, [1] though the plan originated in 1962. [2]
The bridge is formed with 2,650 tonnes of steel [3] and is expected to be completed by mid 2024, [4] at a cost of $160.2M, [5] though budgeted at $135M in 2020, [3] estimated at no more than $60M in 2017 [6] and formerly at $40M. [7] The bridge was delayed by COVID-19 and Cyclone Gabrielle and other storms. [8] The four-lane bridge was designed by Bloxam Burnett & Olliver, and is being built by HEB Construction. [7] It will include bus lanes and cycle paths, [3] and will also carry the Peacocke to Pukete sewer line. [9] The river was closed to boats during construction. [10]
Both banks of the river have been stabilised to support the bridge. The north bank, next to the bridge abutments, has a 50-degree slope, rising 45 metres (148 ft), [11] or 35 metres (115 ft), and was stabilised with 150-millimetre (5.9 in) soil nails. [12] The total length of the bridge is 215 metres (705 ft), [13] including the 11-metre-high (36 ft) mechanically stabilised earth wall of the southern bridge abutment, which is on compressible, loose Taupō Pumice alluvial soils, [11] of the river terraces. The bridge itself is 180 metres (590 ft) long (made up of a 70-metre (230 ft) northern span, 50-metre (160 ft) central span and a 60-metre (200 ft) southern span), 26.2 metres (86 ft) wide, [7] on 38-metre-deep (125 ft), closely spaced, bridge piles, with 35-metre-long (115 ft) earth anchors and over 600 eight-metre-long (26 ft) soil nails. [11] The bridge is over 30 metres (98 ft) above the normal river level. [13]
The main support is a pier on the south bank of the river, [1] formed of weathering steel, in two lattice-shaped, 30-by-22-metre (98 ft × 72 ft) Y sections, each weighing over 200 tonnes. The lattice is made up of 2.2-by-0.82-metre (7.2 ft × 2.7 ft) box-section welded plates. They were lifted into position by a 600-tonne crane. [14]
Installation of a 71-metre (233 ft) curved pedestrian/cycleway bridge weighing over 200 tonnes, made up of five weathered-steel sections, [15] 70 metres (230 ft) north of Peacocke Bridge, was started in 2022. The bridge crosses the extension of Wairere Drive, to maintain the Te Awa link to Hamilton Gardens. [7] Māori design is reflected in the bridge, with two 25-metre (82 ft) steel masts, representing a waharoa (gateway), and influenced by a taurapa (carved waka sternpost). The motif is a takarangi (intersecting spiral), as seen on sternposts, denoting a threshold. [16]
