Upgrade of Esmonde Road Underpass

The existing Esmonde Road Underpass was upgraded as a part of the Northern Busway Project in Auckland, New Zealand. The deck of the underpass needed to be widened by up to 1.5m and raised by a maximum of 500mm to accommodate the modifications required at the motorway interchange. This necessitated extensive strengthening to cater for the new alignment and to comply with current loading standards. The paper describes the upgrade to the bridge with an emphasis on the key constraints faced by the designers and solutions implemented to widen and strengthen the bridge.
