The Waikato Expressway is a dual carriageway section of State Highway 1 in the Waikato region of the North Island of New Zealand that is being constructed in stages. It forms part of the link between Auckland and Hamilton.
Currently, the expressway is made up of four sections: the first beginning at the end of the Auckland Southern Motorway at the top of the Bombay Hills and ending at Longswamp, the second beginning at Te Kauwhata and ending at Ohinewai, the third beginning at Taupiri and ending at Te Rapa and the fourth beginning at Tamahere and ending 2.5 km south of Cambridge. The first two sections are linked by a three lane section of State Highway 1 that will eventually be upgraded to four lanes and thus become a part of the expressway. Further extensions to the expressway are planned, and when completed, the expressway will form a 101.4 km long continuous four-lane dual carriageway from the Bombay Hills to beyond the town of Cambridge, 24 kilometres south-east of Hamilton. When completed, Hamilton, as well as several other towns along the current route of State Highway 1 (such as Huntly, Ngaruawahia and Cambridge), will be completely bypassed by the expressway, allowing through traffic to move much more efficiently.
While not officially designated as the Waikato Expressway until the early 2000s, the upgrading of State Highway 1 from the Bombay Hills to Mercer from 1992 to 1993 can be considered to be the first step in the construction of the expressway. During this upgrade, State Highway 1 from the end of the Southern Motorway to just north of Mercer was upgraded from two lanes to four, with grade separated interchanges constructed at Bombay and the junction with State Highway 2 just north of the township of Pokeno. A bypass of Pokeno was also constructed at this time, as well as several partially separated interchanges to allow access for local property owners along the route.
