Eight persons died in the incident, Anand said.
As many as five persons were rescued and were undergoing treatment, Padra police inspector Vijay Charan said.
Gujarat minister Rushikesh Patel said the bridge was constructed in 1985, and its maintenance was carried out periodically as and when required.
“The exact reason behind the incident will be probed,” he said.
Chief Minister Bhupendra Patel has directed technical experts to reach the site and conduct a probe into the reason for the collapse, he said.
Visuals showed the entire slab of the bridge between two piers having collapsed.
The incident occurred at around 7.30 am and the vehicles that fell into the river included two trucks and two vans, inspector Charan earlier said.
Teams from Vadodara fire department and locals joined the rescue operation which was still on, an official said.
A team of the National Disaster Response Force (NDRF) also reached the site, the official said.
The nearly 900-metre-long Gambhira bridge has 23 piers and connects Vadodara and Anand districts of Gujarat. It was inaugurated in 1985. PTI COR KA PD GK
