Hawke's Bay Expressway Southern Extension, New Zealand
Hawke's Bay Expressway in New Zealand connects Flaxmere, west of Hastings, and Napier Airport. Flaxmere and Napier Airport are connected through Taradale, a town in the Hawke's Bay region.
The expressway is a single-lane route with roundabouts at Prebensen Drive, Taradale Road, Evenden Road, Omahu Road and Flaxmere Avenue / York Road. It has interchanges at Kennedy Road and Meeanee Road.
The state highways that are incorporated include State Highway 2B (SH2B), State Highway 50 (SH50) and State Highway 50A (SH50A).
The first section of the expressway opened in the early 1960s. Construction work on the second section started in the 1990s. In 2003 the new bridge (expressway) to Hawke's Bay Airport was opened.
The Hawke's Bay Expressway Southern Extension (HESE) project involved the extension of SH50A by 3.2km. The project, conceived in 2007, was intended to reduce traffic congestion and the number of accidents. Extension work started in October 2009 and was completed in March 2011.
Previously, the existing expressway terminated at an upgraded "four-legged" roundabout, while the new extension started at the same point. The extension was carried out southwards to a new "five legged" roundabout.
HESE project extended the last section of the Hawke's Bay Expressway. The project work was carried out between Hastings City and Flaxmere.
The extension project provided a direct route between the roundabouts on York Road and Longlands Road. The project reduced travel times for commuters. It removed the bottlenecks and crash blackspot at the York Road / Maraekakaho Road T-intersection and supported the future growth of transportation and infrastructure in the region.
Safety was made a priority, as the expressway is the main route through the region. The southern extension project enhances the safety of the expressway through an uninterrupted link. To achieve this, no connections have been provided between the expressway and local roads and no private access road.
The extension work included construction of 3.2km road through greenfield areas and realignment of a portion of Maraekakaho Road to connect the expressway and Longlands Road. The project also involved the removal of the T-intersection to reduce congestion.
The project was carried out over two years. During the first year, work took place in the greenfields area. During the second year connections to existing roads at both ends of the expressway were built and work was carried out at the York Road intersection.
During the second year of construction the three-legged roundabout at the York Road intersection was converted into a four-legged roundabout.
The extension project has also divided Irongate Road into two equal roads, one on each side of the expressway. These two roads are accessible through Stock Road and Maraekakaho Road.
The project required an investment of NZD$12m. New Zealand Transport Agency Board provided about NZ$12m from regional funds. The regional distributed funds were approved by Hawke's Bay Regional Land Transport Committee..
Opus International Consultants was awarded a contract to undertake the design and construction management of the southern section extension project. Construction was carried out by Higgins Contractors. Most of the contractors and sub-contractors of the project were regionally based.
