An £89.5 million project has been given the go-ahead for new traffic management and driver information systems to be set up on the notoriously busy A14.
The scheme will cover 62 miles of the dual carriageway, from the M1 in the west to Felixstowe in the east.
It will eventually provide road users with journey time information, warnings of upcoming congestion and advice on alternative routes.
The scheme will see automatic incident detection sensors embedded in the road surface providing real-time traffic information to electronic signs installed above the road.
This will allow traffic to be re-routed following road incidents, giving drivers a choice of routes.
Incident monitoring cameras will also be installed to allow Highways Agency traffic officers to respond more quickly to incidents.
