Executive Summary This report describes a study commissioned by Transit New Zealand (Transit) into a recommended future strategy for State Highways 1 and 16, between Auckland and Wellsford. The purpose of the study was to identify the future function and format for each state highway, and to provide guidance on what level of transport investment would be required on each of the state highway corridors. SH1 and SH16 both provide transport routes between Auckland and Northland, although each route is significantly different. SH1 is the primary choice for travel between Auckland and Northland whilst SH16 provides more regional functionality, linking the townships along it to the Auckland and Northland areas. There is also little through traffic between Auckland and Wellsford on SH16, except during holiday periods when Transit encourages use of this route to avoid delays on SH1 at Orewa. The study investigated future transport needs for a period up to 2050. This time horizon is consistent with the Auckland Regional Growth Strategy (ARGS), which defines how land use development will take place in the region, out to 2050. The study area, which is predominantly in Rodney District, is experiencing significant growth in residential development and economic activity which is likely to continue. Therefore an approach was adopted to test the amount of development which might occur over the timeframe of the ARGS, and then examine what the travel demands of this future scenario would entail. The study was undertaken in two parts; the first part focused on options for the strategic function of both state highways, and reached a conclusion about which option was preferred. In the second part, work was undertaken to determine how functionality in the recommended strategy could be implemented, taking account of factors such as economic development, environmental issues and viability. Transit New Zealand published its National State Highway Strategy (NSHS) in 2007, which outlined a new system of defining functions of state highways into three separate categories, national, regional and sub-regional. Strategy options were developed which different functions for each of SH1 and 16 (plus a new inland route), recognising that the national function must be maintained to provide the critical strategic link between Auckland and Northland. After a careful review of the needs, issues and constraints in the study area the recommended strategy which emerged from a LTMA based evaluation framework, was retention of the functions defined in the NSHS, namely the national function on SH1, with SH16 fulfilling a regional function. This concept is shown on Figure 1-1 overleaf.

With a focus on moving more people and goods rather than just providing more traffic capacity, several opportunities for alternative modes were explored, including bus and rail. A substantial proportion of freight moving between Northland and Auckland is already moved by rail; however logistical issue suggest that opportunities to move significantly more freight by rail are limited. Transit had already investigated extending the Northern Busway to Silverdale, which will provide for the growth in commuter travel from the Hibiscus Coast to Auckland.
