£200m A47 Thickthorn Road Revamp to Cause Two Weeks of Delays Starting February 16
The A47 Thickthorn road revamp will induce two weeks of delays starting February 16 due to engineering works. Temporary two-way traffic lights will be installed and operated 24/7, managed by High Voltage Systems and Services (HVSS) for utility upgrades. Skanska, appointed by National Highways, is overseeing the £200m project that began in January 2025, which includes new slip roads to alleviate congestion. Additionally, the eastbound A47 will close on February 8 for transformer deliveries related to the Hornsea 3 Offshore Wind Farm.

Starting February 16, drivers will face two weeks of delays on the A47 Thickthorn due to engineering works for a £200m road revamp. Temporary two-way traffic lights will be operational 24/7, managed by High Voltage Systems and Services (HVSS) for low-voltage power supply upgrades.
The project, initiated in January 2025 by Skanska under National Highways, aims to relieve congestion with new slip roads connecting the A47 and A11. Additionally, there will be a closure of the eastbound A47 on February 8 for large transformer deliveries for the Hornsea 3 Offshore Wind Farm project.
