The reason for the third cable-stayed bridge is to accommodate heavy traffic, especially during the peak year-end tourist season.

[citation needed] On 14 June 2014, Indian Prime Minister Narendra Modi laid the foundation stone for the third Mandovi bridge.

[4] Larsen and Toubro (L&T) were awarded the EPC contract at a bid of ₹403 crore (US$47 million) to build and design the bridge.

[7] The main bridge is 600 m in length with two end spans of 75 m and three interior spans of 150 m. The main bridge superstructure consists of a 21 m wide externally strutted segmented concrete box girder with a dual carriageway of 2 x 8.5 m with a 3 m wide median at the centre.

Another flyover arising from the Merces-Old Goa bypass road joins the Mandovi bridge for traffic from Ponda towards Panjim.

[8] The Goa State Infrastructure Development Corporation (GSIDC) said that almost 100 million litres of water was saved while building the bridge.

[14] On 30 December 2017, a fire broke out on an under construction pier supporting the cable-stayed bridge; however, there were no casualties and the situation was brought under control.

[16] Due to high wind speeds, GSIDC announced that two-wheelers and three-wheelers are prohibited from using Atal Setu.

However, the mangroves will be replaced at suitable sites identified by the Forest Department, and marine ecology will be restored as stated by the EIA.
