Provincial highways are major roads that connect cities and towns within a specific province. They are maintained by the provincial government and are designed to facilitate transportation for both personal and commercial vehicles. These highways often link to local roads and can vary in size and capacity, accommodating different levels of traffic. In many regions, provincial highways play a crucial role in economic development by providing access to markets, resources, and services. They are essential for tourism, agriculture, and industry, helping to support the overall infrastructure of the province. Examples of such highways include Highway 401 in Ontario and Trans-Canada Highway that spans multiple provinces.
