History

The Mandovi bridge is one of the most famous and longest bridge in Goa. Before the bridge was built, the ferry was the main mode of transport across River Mandovi well into the 1970s between Panaji and Betim village. Due to heavy traffic the first bridge was built in the 1970s. Later in 1986 the first bridge collapsed and was later rebuilt. The second bridge was constructed in 1998 in order to accommodate heavy transport vehicles. The third bridge is under construction which began in 2014. The reason for the third cable-stayed bridge is to accommodate heavy traffic especially during the peak year end tourist season. Larsen and Toubro (L&T) were awarded the EPC contract at a bid of ₹ 24.24 crore to build and design the third bridge.

On 14 June 2014, the foundation stone for the third Mandovi bridge was laid by Indian Prime Minister Narendra Modi. The third bridge will be cable stayed bridge constructed between the first and second parallel bridges which will be spanning over 3 kilometers and would be 15 meters higher than the existing two bridges.^[6] The third bridge will be designed and constructed by Larsen & Toubro (L&T). The bridge will be a 900 m four lane bridge will be a 550 m cable stay portion and a 3.2 km viaduct approach. The main bridge is 600m in length with two end spans of 75m and three interior spans of 150m. The main bridge superstructure consists of 21m wide externally strutted segmented concrete box girder with dual carriageway of 2 x 8.5m with 3m wide median at the centre. The box girder will be supported by stay cables which will be anchored in the pylon and stressed from box girder bottom. Another flyover arising from the Merces-Old Goa bypass road will join the Mandovi bridge for traffic from Ponda to go towards Margao. The revised cost of construction of the particular bridge being built is ₹ 860 crore and the cost could increase by ₹ 50 crore. It is the third longest cable-stayed bridge in India.


Mandovi Bridge is one of the most heavily used bridges in Goa. According to GSIDC sources almost 66,000 vehicles travel over the Mandovi bridge everyday.
