N03/06 Redesign of Pfäffikon Junction

The junction that went into operation on a green-field site in 1968 is now subject to heavy incoming and outgoing traffic as a result of today’s population spread. Redesigning the junction should alleviate the current traffic problems and prevent tailbacks on the main line of the N03. A high bridge is foreseen which will directly  link the the heavily frequented “Seedamm” Shopping Centre with the N03. Further measures are planned which will adapt the 40-year-old junction to current road construction standards.
