Tenerife is moving from a two-way, sometimes-gridlocked island into a more connected, higher-capacity transport network. Two big infrastructure stories are converging: (1) a major program to add a third lane on key stretches of the TF-1 in the south, and (2) the finishing work on the Erjos Tunnel — the western link that will complete the island’s “anillo insular” (ring road) and finally join the TF-1 and TF-5 by the west. Both projects promise to reshape travel times, commuter flows and — crucial for readers of InvistaForum — local real-estate dynamics.
