The region in and around Christchurch, encompassing Christchurch city and the Selwyn and Waimakariri districts, contains more than 800 road, rail, and pedestrian bridges. Most of these bridges are reinforced concrete, symmetric, and have small to moderate spans (15–25 m). The 22 February 2011 moment magnitude (Mw) 6.2 Christchurch earthquake induced high levels of localized ground shaking (Bradley and Cubrinovski 2011, page 853 of this issue; Guidotti et al. 2011, page 767 of this issue; Smyrou et al. 2011, page 882 of this issue), with damage to bridges mainly confined to the central and eastern parts of Christchurch. Liquefaction was evident over much of this part of the city, with lateral spreading affecting bridges spanning both the Avon and Heathcote rivers.

The piece of land circumscribed by the loop of the river is all zoned red, as is the land to the left of the photo. On the right, most of the land is zoned green or orange".

20111230_7222_1D3-70 New Brighton Further damage to the bank following the two quakes on 23/12/11. The sewer line broke here and was repaired (patched) by council staff on Christmas Eve. It is hard to beleve that this rock wall was level with the land here, before any of the quakes. #2004
