A new centre island, vehicle-activated speed limit signs, and rumble strips will be installed along A1306 New Road, between Lambs Lane and Sandy Lane.
Around 1,700 cars use the road every hour, according to a previous Havering Council report.
Despite the current signage, speeds of 60mph – 20mph above the speed limit – were “regularly recorded”.
Nine crashes were reported between April 2019 and April 2024. Of those, one was fatal, while two occurred in wet conditions and another happened at night. Two-thirds happened between the hours of 10am and 4pm.

The central island will be installed between Wennington Road and Sandy Lane.
Rumble strips will run along the A-road north and south of Wennington Road, and the council will paint double yellow lines along Wennington Road and the hotel access road.
In a bid to declutter the road, the highways teams will also remove the Ultra Low Emissions Zone (ULEZ) signage and prune overhanging tree branches. Signs warning of slippery hazards will also be taken down.
The £40,000 scheme was signed off by cabinet member Barry Mugglestone on March 6.
It will be paid for by money ringfenced for the council by Transport for London.
