Cienco4 Group is planning a major overhaul of a 35.1km section of National Highway 1A, covering areas from south of Ben Thuy Bridge to the Ha Tinh City bypass in the Nghệ An and Hà Tĩnh provinces. The project is being developed under a Build-Operate-Transfer (BOT) model, with construction expected to run from November 2026 through 2027. The investor cited revenue decreases due to toll reductions and the opening of alternative routes as reasons for seeking new capital mobilization solutions.

In response to construction activities on National Highway 1A, Hanoi has implemented adjustments to several bus routes. These changes affect lines connecting the Thường Tín area with Hà Đông and surrounding locations, with new terminal points established at the Him Lam 1 Urban Area.
