Replacement Ferrymead Bridge to reopen to traffic
The replacement Ferrymead Bridge will open to traffic this weekend, four years on from the February 2011 earthquakes that caused significant damage to the original bridge and ground conditions under the Ōpāwaho / Heathcote River.
Councillor Phil Clearwater, Chair of the Infrastructure, Transport and Environment Committee, says the return of traffic to the main Ferrymead Bridge is another sign that the Christchurch rebuild is on track.
“This is a significant milestone for the ongoing Christchurch rebuild. This project has been one of the most challenging engineering projects for the city, especially given the complex foundation conditions in this post-earthquake environment.
“This project has taken longer than normal, but what we need to understand is the very different and unforeseen events and conditions that we in Christchurch have to live and operate in. We have made sure that we evaluated all safety and structural options to ensure the bridge is capable of withstanding earthquake events exceeding those experienced during the Canterbury Earthquakes. Safety is paramount, so fully examining all aspects of the design and construction of the replacement bridge was a major factor for this project.
“Due to the unique ground conditions in this area, complex engineering solutions needed to be incorporated into the construction of the replacement bridge. As well as supporting the new road-deck, crucially, the bridge houses essential lifeline services such as communication and power cables, and sewer and water supplies to the local community,” Councillor Clearwater says.
Following the reopening of the main road deck this weekend, there will be further work on the road approaches to the bridge. All four lanes will be open to traffic by July 2015, when the project is scheduled to be complete. Final landscaping is due to take place in Spring 2015.
General Manager Infrastructure Rebuild John Mackie says the patience shown by the local community has been great and helped the project progress on schedule.
“We can’t thank to the local community enough for its patience throughout this project. We understand the significance of this bridge to people who regularly travel out this way. We have been conscious of the works impacting on people’s journey times and will continue to do our best to minimise this, right through to the end of the works,” Mr Mackie says.
The total cost of the project is $34.87 million of which the New Zealand Transport Agency (NZTA) has provided approximately $22.12 million.
