Three weeks of road closures on the A41 near Watford are set to get underway from 9pm today.

Hertfordshire County Council's Highways teams will shut the southbound carriageway between Two Waters Way slip road, Hemel Hempstead, and the M25 junction 20 roundabout at 9pm to improve the road surface.

It will reopen at 5am tomorrow (July 16) and then be repeated each night from Monday to Friday until August 3.

A Highways spokesperson said: “We're resurfacing the road for the comfort and safety of all road users and stabilising the road's foundation to reduce future maintenance.

“Over time, the road's surface has become worn due to the high volume of traffic.”

The work will include renewing the old road surface, ground stabilisation, cleaning drains, and reinstating road markings and studs.

Only emergency vehicles will be allowed access through the work hours, which is being carried out at night “in order to create a safe environment for the workforce and members of the public alike”.
