As of 2016, the city continues to grow rapidly. Development is focused on the northern end of the city although in 2012 the council made a decision to balance the city's growth by approving an urban development to the south. Traffic congestion is increasing due to population growth, though the council has undertaken many road development projects to try to keep up with the rapid growth. State Highway 1 runs through the western and southern suburbs and has a major junction with State Highway 3 south of the city centre, which contributes to congestion. The Hamilton City Council is building a 2/4-lane arterial road, Wairere Drive, through the northern and eastern suburbs to form a 25 km suburban ring road with State Highway 1, which is due for completion in early 2015., while the New Zealand Transport Agency plans to complete the Hamilton section of the Waikato Expressway by 2019, easing congestion taking State Highway 1 out of the city and bypassing it to the east.
