The driver involved in the 7-vehicle crash on the Sakonnet River Bridge is saying brakes were to blame for the collision. 

The driver, who has not been identified, reportedly told police his brakes failed, reports The Providence Journal. The crash remains under investigation. 

Three police cruisers were struck during this multi-vehicle crash Monday morning on the Sakonnet River Bridge. 

This was the second major vehicle crash to occur on a Portsmouth bridge in three days. On Saturday night, a Barrington man was killed and five other people were injured after a head-on collision on the Mt. Hope Bridge. 

No injuries were reported in the crash on Monday. 

According to The Providence Journal, the Sakonnet River Bridge was shut down for more than two hours Monday morning after a dump truck carrying rocks sideswiped a vehicle and struck a police cruiser. The truck was passing a minor two-vehicle crash at the time. The bridge has since been re-opened. 

Portsmouth police later released the following statement: 

On Dec. 3, 2012 at approximately 9:25 A.M., while two Portsmouth Police officers were investigating a motor vehicle accident in the south bound lanes of the Sakonnet River Bridge, the operator of a dump-truck, who was approaching the scene, lost control of his truck.

As a result, the dump-truck forced a Tiverton Police car into the Jersey-Barrier and struck a total of six vehicles including two Portsmouth Police cars. However, there were no reported injuries. The cause of the accident remains under investigation by the Rhode Island State Police.

This incident occurred the same day as a hearing on proposed tolls for the Sakonnet River Bridge, which spans Portsmouth and Tiverton. 

A second hearing on bridge tolls is scheduled for tonight at 7 p.m. at Tiverton High School.
