Alongside efforts to dredge the Co Co River (also known as Lo Canh Giang) to restore a 28km waterway connecting the Han River in Da Nang to the Dai River in Hoi An, Da Nang and Quang Nam Province are working to develop riverside infrastructure, including bridges crossing the river. These projects contribute to the economic and social development of the two localities.
Before becoming silted, the Co Co River was the busiest inland waterway in the 18th and 19th centuries. Currently, both Da Nang and Quang Nam are making efforts to restore its flow. In Da Nang, dredging of the river is largely complete. The Co Co Bridge, the road across the river, and Bai Dai Bridge have been constructed, enhancing the landscape in the city’s southern urban areas.
The Co Co Bridge and Road Project
The Co Co Bridge and Road Project commenced on February 3, 2020, and was inaugurated on October 30, 2021. As part of Da Nang's Transport Infrastructure Improvement Project, the project cost VND 172 billion in total. Managed by the Management Board of the Da Nang Priority Infrastructure Investment Project, the project utilised ODA funds from the OPEC Fund for International Development and counterpart funding from Da Nang.
The project has been identified as a key motivational project for Da Nang, as highlighted in Resolution No. 266/NQ-HDND dated December 12, 2019.

 |
| The total length of the route is 1,163m, with a designed speed of 50km/h and a width of 33m, accommodating six traffic lanes. |
 |
| Technical infrastructure, including drainage systems, green spaces, irrigation, and lighting, has been comprehensively developed along the route. |
 |
| The Co Co Bridge spans 113.8m and is 27m wide, featuring three spans of 25m + 50m + 25m, constructed with a reinforced concrete arch structure. |
 |
| The project serves as a main traffic axis connecting the city centre, the international airport, new residential areas in the southeast (such as Hoa Xuan Ecological Urban Area and FPT Technology Urban Area), and coastal resorts with Hoi An Ancient Town in Quang Nam Province. |
Bai Dai Bridge
Bai Dai Bridge, along with Hoa Phuoc Bridge in Hoa Vang District, is part of the Southern Ring Road Project in Da Nang. The project, valued at approximately VND 1 trillion, was funded by ODA from the World Bank and Da Nang's counterpart funding.
Construction began in June 2012, and the bridge was inaugurated on May 19, 2014. The project’s main component is the 6.79km Nam Ky Khoi Nghia Road, designed as a secondary urban arterial road with a speed limit of 70km/h. It connects National Highway 1A in Hoa Phuoc Commune with the FPT Technology Urban Area in Hoa Hai Ward, Ngu Hanh Son District.
 |
| Approximately 1km from the Co Co Bridge is Bai Dai Bridge (formerly known as the old Co Co Bridge), located within the FPT Technology Urban Area |
 |
| Bai Dai Bridge spans 90m in length with a width of 19m. It also serves as the endpoint of the Southern Ring Road in Da Nang. |
 |
| Bai Dai Bridge, together with Nam Ky Khoi Nghia Road, the Hoa Phuoc - Hoa Khuong Ring Road, and the Western Ring Road, forms a seamless transportation axis connecting Hoa Vang District with National Highway 1A and Ngu Hanh Son District. |
 |
| Bai Dai Bridge borders the Innovative Subdivision Planning Area, approved by the Da Nang People's Committee under Decision No. 1687/QD-UBND dated August 5, 2024. |
 |
| In the future, this area is set to become a hub for education, integrated with the University Urban Area, an Innovation Centre, a Software Park, and a regional healthcare centre. |
Bridges Across the Co Co River in Quang Nam Province
The 19.5km stretch of the Co Co River in Quang Nam Province is seeing the construction of several bridges such as Thon 3 Bridge, Nguyen Duy Hieu Bridge, Nghia Tu Bridge, Phuoc Trach Bridge, and De Vong Bridge, contributing to the river’s landscape and the region’s economic development. Among these, Nghia Tu Bridge, located in Dien Duong Ward, Dien Ban Town, is currently under construction.
 |
| Thon 3 Bridge is in Dien Ngoc Ward, Dien Ban Town, Quang Nam Province, near the border with Da Nang, and construction began in April 2022. The bridge is 22m wide, with 4 vehicle lanes measuring 15m and pedestrian paths with railings on both sides, each 3.25m wide. |
 |
| Nguyen Duy Hieu Bridge spans 242.4m and is 20.5m wide, featuring 4 vehicle lanes. It connects the DT603 coastal road,linking Da Nang and Quang Nam, with Cam Kim Bridge (Hoi An) and National Highway 14H, and was opened for technical use in April 2022. |
 |
| Phuoc Trach Bridge, approximately 70m long and 3m wide, crosses the De Vong River, a section of the Co Co River in Hoi An. This historic bridge is currently under renovation and lies on National Highway 14H, a key route linking the Cua Dai coastal area with the centre of Hoi An. |
 |
| De Vong Bridge, also in Hoi An, spans over 260m and crosses the De Vong River. Completed in December 2018, it connects critical coastal roads such as DT603 and the Cua Dai - Vo Chi Cong Road, reducing traffic pressure on Phuoc Trach Bridge. |
