SAFETY improvements are due to be carried out overnight next week on the southbound carriageway of the A405 North Orbital Road near Bricket Wood.

Work is scheduled to be carried out between 10pm and 5am when traffic flows are at their lowest and one lane will remain open at all times on each carriageway during working hours.

The project is to install new signs between Junction 21a of the M25 and Junction 6 of the M1 with a view to improving driver awareness of the approaching traffic signals and junction.
