The Helsinki-Hämeenlinna-Tampere growth corridor is the most significant development zone in Finland. The corridor has remained on the agendas for years – now it has become more vivid also for companies and citizens. To strengthen the functioning corridor in everyday life, development ideas were combed out in two workshops. MDI facilitated the transport themed workshop in April in Hämeenlinna. The client is Project HHT coordinated by Anna-Mari Ahonen from the city of Hämeenlinna.
