PHNOM PENH: Shanghai Construction Group built the Third Ring Road project, which had a whopping investment of $300 million.

The construction was monitored by Guangzhou Wanan Technical Consulting, but it faced some delays due to compensation issues for the locals, unfavorable weather, and the Covid-19 pandemic.

Originally, the project was supposed to be completed within 42 months. The first phase of the semi-circle starts from National Road 4 to National Road 1, comprising a total length of about 52,983 km.

While the section passing through Kandal province covers nearly 38 km, the one traversing Phnom Penh spans around 15 km.

The inauguration of the third ring road's construction project is set for June 30, as confirmed by Prime Minister Hun Sen during the Phnom Penh-Bavet Expressway and Expressway Bridge's groundbreaking ceremony on June 7, 2023.
