The highway Ruta Nacional 90 (between Barranquilla and Santa Marta) is heavily endangered by progressive coastal erosion. Principally, this has a natural cause since the shifting mouth of the Magdalena River led to an insufficient supply of sediment. However, this threat has been foreseen for decades without it leading to adequate planning or countermeasures. The measures of the last couple of years have led to mostly ineffective and costly hard protection structures. The location of the road, through national park Via Parque Isla de Salamanca and the proximity of national park Ciénaga Grande de Santa Marta, increases the complexity and requires an integrated approach. The multidisciplinarity of the project team, consisting of master students of Hydraulic Engineering, Building Engineering and Construction Management & Engineering, facilitated this integrated approach. It is researched how the transport function between Barranquilla and Santa Marta can be safeguarded for the next 50 years in a sustainable way. Three long term strategies are researched: maintain the current coastline, retreat behind a future coastline or adapt by improving the infrastructure on the current trajectory. Short term strategies are researched in order to bridge the implementation time of a long term strategy. The report gives an indicative overview of the different strategies based on relatively rough data. The retreat option is deemed to be the most sustainable and cost-effective solution in the long term.
