Motorists on their way into and out of Chelmsford are being advised to allow extra time for journeys over the next few weeks because of scheduled maintenance works to the Army and Navy flyover.
Following works undertaken in April, maintenance will be carried out on the parapets and main traffic control and sign system.
Essex Highways is also considering reducing the speed limit on the flyover on a permanent basis from 30mph to 20mph as an additional safety precaution.
The flyover will be fully closed (24 hours a day in both directions) from 9pm on Monday 23 July until Monday 13 August 2018 when it is expected to reopen at 6am.
The flyover will remain closed during the daytime to allow engineering works to take place over the central roundabout. Works will take place at night over the carriageway supported by temporary lane restrictions.
In addition, a partial roundabout closure will be necessary for approximately 3 consecutive nights during the works. Details will be advertised in advance on site signage, and drivers will be required to use local alternative routes and signed diversions which will be in place during these periods.
Access to subways will remain open and staff will be on-site where necessary to guide pedestrians.
Essex Highways urge all users of the roundabout to take additional care during the works, allowing extra time, observing signage and traffic management in place.
