In this context, the mission of designing the U4 Blast Furnace park entrusted to the TER agency consists in proposing a guide plan of the spaces and a mission of project management on all the spaces accessible to the public.
Faced with these uncertainties and following preliminary studies, the TER Agency proposed to compose its development by framing the entire site in the form of plots of 7X35m constituting the basic unit for any implementation of a future project whatever its nature (construction, parking, phytoremediation garden, pending plot etc …).

Materialized by the establishment of more than 500 milestones these plots are crossed by a central path called “Traverse”. The Traverse makes it possible to walk and cross the site by scenographic the industrial character of the place and by composing with the mutable and evolving character of a site whose uses and occupation are currently only anticipated. The Traverse, a real backbone of public spaces, thus strives to stage the visible traces of industrial activity (use of materials from the site, conservation of old coatings and rails, etc. etc.).
