Who we serve

At MassDOT, transportation is not about roads and bridges, or trains and buses – it is about people. Our mission begins with customers - individuals, businesses, municipalities, and regional transit agencies. We support programs and projects that deliver a high return on investment. We partner with municipalities, public agencies, and private sector businesses. MassDOT supports the economic, quality of life, and environmental goals of the Commonwealth.
