New Zealand's Bridges: Moorehouse Overbridge across Colombo Street in Christchurch (1)

March 2011 (-43.540 Degrees, 172.637 Degrees) Moorhouse Overbridge

My last bridge from Christchurch, New Zealand is the Moorhouse Overhead. It is an eleven span T girder bridge that carries Moorhouse Avenue quickly up and over Colombo Street. It was built with split columns and expansion joints at the 1/3 points. Later, one of the expansion joints was locked up, resulting in unsymmetrical motion and a lot of damage during the February earthquake (see figure below). We'll take another look at this bridge tomorrow.
