To see the ministers : Minister of the Department of Transportation and Infrastructure (New Brunswick) As part of its duties in maintaining the provincial highway network, the Department of Transportation is responsible for the operation of a number of ferry services.

[3][4] The department is responsible for building and maintaining all public roads in areas of provincial jurisdiction.

Additionally, some numbered public roads that pass through municipalities are also built and maintained by the department.

In 1997 the department changed the way that it finances and builds arterial highways by utilizing what is known as a "design-build-operate" tendering process.

This began with the Moncton-Longs Creek section of Route 2 which started as a toll highway but was changed to a hidden toll arrangement whereby the provincial government pays the charges for vehicle usage and the company that built the highway operates and maintains the road for a period of 25 years after it opened in 2002.
