In 2008 a strategic study of the route was carried out by the New Plymouth District Council and the NZ Transport Agency (formerly Transit NZ). During the strategic study a variety of groups and individuals provided feedback, identifying issues with the road and suggesting how it could be improved.
In 2010 the Transport Agency investigated a number of improvements that could be made to address the issues identified in the study and ensure that this important link with the CBD, port, industrial and residential areas support different transport needs. When investigating the improvements, the Transport Agency reviewed growth projections and identified long-term and medium-term solutions.
In 2013 the Transport Agency asked the community to give feedback on the proposed designs. Following this feedback the designs were updated. These designs provide a medium-term solution in order to address the issues on the route, whilst also undertaking other future proofing actions such as the addition of new bridges.
