Incheon Aam1gyo Reduced from 8 Lanes to 4 Lanes Starting Next Month 18... Underpass Construction

A 930m section around Aam 1-gyo on Aam-daero, Songdo, Yeonsu-gu, Incheon, will be reduced from 8 lanes to 4 lanes starting from the 18th of next month.

Incheon City announced on the 21st that the lane reduction is due to the construction of the Aam Underpass. The section from Songdo 3-gyo Intersection on Aam-daero, the main road of Namhang, to Ongam Intersection has frequently experienced traffic congestion, and there have been continuous complaints about the lack of accessibility between the new port and the old downtown area, necessitating the construction of an underpass around Aam 1-gyo.

Accordingly, the city signed an agreement with the Incheon Regional Maritime Affairs and Fisheries Office for the construction of the underpass and received national subsidies to newly build the Aam Underpass by November 2025 according to a phased traffic management plan. Since August, the city has been opening detour roads for phases 1 and 2.

The phase 3 plan is to open 4-lane detour roads on both sides of the main section before the full-scale start of the underpass construction in December, securing the construction area and temporary traffic routes.

From the 18th of next month, vehicles heading towards Incheon (from Songdo 3-gyo Intersection to Ongam Intersection) must use detour roads via Anggogae~Neungho-daero or Art Center-daero~Incheon Tower-daero from Songdo 3-gyo Intersection. Vehicles heading towards Sorae (from Ongam Intersection to Songdo 3-gyo Intersection) must use detour roads via Neungho-daero~Anggogae or Incheon Tower-daero~Art Center-daero from Ongam Intersection.

During the underpass construction period, the city will maintain pedestrian convenience by opening detour roads within the main section to keep traffic routes open. Vehicles passing through the section will be guided to detour roads through traffic broadcasts, navigation systems, and promotional media to minimize traffic inconvenience.

An official from Incheon City said, "Once the Aam Underpass is constructed, traffic congestion will be alleviated and accessibility between the port and the old downtown area will improve." He added, "Although it may be somewhat inconvenient, we ask vehicles passing through the construction area to use the surrounding detour roads as much as possible."
