Classified as a large-scale project by the MTC, this road will provide greater safety to passers-by, as various landslides have been recorded in this area, justifying its classification as critical sector. Likewise, the construction of a tunnel will also prevent traffic to the center of Ollachea from being interrupted by falling rocks on the highway.

The Ollaechea Avoidance road extends 1274.00 m from South to North and starts at the junction of the future Ollaechea Tunnel at km 232 + 572.546. It, then, runs along the existing Interoceanica Sur highway until it meets the entrance to Ollaechea town, continues, adapting to the terrain morphology, through the 144.68 m long Bridge 1, followed by a sharp turn to finally cross the Osjo River ravine, through the sloped and curved 129.60 m long Bridge 2, connecting to the existing Interoceanica Sur highway at km 233 + 846.637.

The value of the works amount to USD 23 774 534 and are scheduled to end in February 2023, 28 months after starting.
