Introduction: Urban consolidation development is associated to motility, in great part if is referred to HIGHWAYS. Involving own and autonomy logics, they results functionality exclusively to its purpose: to content and conduce in an efficient way vehicular fluxes, starting from impose its own spatial conditions -
support structures, organizing under and upper level of bridges panels, tunnels, visuals screens, and so on-. The territorial sector where it happens this descending is affected because of a domineerig lineal
sequence of different categories of impacts entailed besides to urban consolidation level.
As a product of interaction between Fix and Fluxes -TERRITORY/ HIHGWAYS-, is that appears urban Interstitials Situations, faced here from an investigative origin where Interstice was understood as the
difference between previous territorial entities and new ones superposed, redounding in material or functional hybridization of respective original conditions, and boarded as a product of social, and spatial
actions and relations. So, this interstitial space, was considered unavoidable information when boarding operations over urban areas in relation with motility fluxes highways.
Objectives: The research, presently in development pretends to fix regulations and strategies appointing to a systematically formulation of typological patterns taking in account interstitially space, unavoidable
information to face actions over urban areas in relation with motility high-way fluxes and appropriation in the under high-way.
Methodologies: Is based in data emerging from the application of a reading and systemic interpretation instrument appointing to the complexity of urban tissue and the superposition of physics and phenomenological layers, -Interstitial Tool-, in interstitials situations “under highway” in a fragment of the Buenos Aires Metropolitan Region / RMBA – Argentina. By other way, digital descriptions are used as the best choice for representing all this process –still unfinished-, by the application of digital methods to board
the understanding of the mentioned urban problematic.
Conclusions: Generic conclusions as result of the analysis, put in evidence that the motility high-way fluxes cuts/sections the CITY, accepted its implantation and descent as a consummated fact in account of
territorial connectivity. SPATIAL DETERMINING (modulation, support, way-cover between others), conditions appropriations in that way, that it doesn’t matter character of the insertion contour; context and highway establishes a nexus; an urban adequation (voluntary or involuntary) that cannot avoid that programs and uses doesn’t fall into a sort of accepted status quo, even if in much cases have no difference from proper uses of the insertion area; conflict takes possession of the scene and its uses, all that because the highway leaves in its “under” a sort of confusion between public and privat activities,
adding to this, the incidence of the supporting structure and upper plane that conduces always to not resulted conditions and/or conflicts proper from this kind of infrastructures over territories when there isn’t governmental diagnostics and actions-.
The evaluation of specific conditions of habitability of the interstitial situations mentioned, must be boarded to be changed, as well as those cases apt to be optimized, producing a reconfiguration of present
situation. There is a responsibility about a simultaneous design of the upper and under highways. The unavoidable bond between urban development and motility must depend on, own instruments that overview those spaces , not as remnants of another intervention but in a sustainability way, compatible with preservation and an natural and urban ambient improvement, contributing to all that makes direct or indirectly to construct the social capital of urban areas.
