The project includes about 38 km of existing bicycle lanes and the possibility of expanding this infrastructure by 23 km to complete the anticipated "MinGrid"; The connection/fluidity of the existing infrastructure for bicycles at intersections as part of the overall traffic solution, the treatment of intersections for rehabilitation, innovative elements in the infrastructure, horizontal, vertical and traffic signals in order to improve the quality, safety elements in relation to the optimal solutions of the multimodal circulation in the nodes and longitudinal extension, will be carried out through these phases: PHASE I: Preliminary Design for at least 2 options (Preparation and planning of the design) PHASE II: Final preliminary design for the best option (system and integration planning) PHASE III: Processing and submission of documents for the necessary legal procedures for approval of the construction permit. PHASE IV: Detailed design: Elaboration and presentation of the solution plan for implementation. PHASE V: Final cost estimation and BoQ
