The proposal includes expanding the current Rung Sac route to eight main lanes for motor vehicles and two parallel lanes.

The expanded road will run from the Ben Luc–Long Thanh expressway interchange in Binh Khanh Commune to a planned coastal urban development project in Can Gio.

A separate section would build a nearly 2km connecting road linking Route 15B to the future Can Gio bridge project, designed with six lanes including four for vehicles and two parallel roads.

Rung Sac Road, about 36km long, is currently the only land route connecting the city center to Can Gio, running through mangrove forests and linking sparsely populated areas to the coastal commune.

Traffic to Can Gio relies heavily on the Binh Khanh ferry, creating bottlenecks and long queues during peak periods, particularly as travel demand rises on weekends and holidays.

Authorities expect traffic to increase further as Can Gio is planned for development into a marine economy and eco-tourism hub, with major infrastructure projects, including a proposed bridge linking the commune to southern parts of the city.

The planned expansion is intended to improve connectivity to support economic and tourism development in the area.
