Motorists have been warned to expect disruption and delays as work continues to upgrade the Sydenham Bypass.

The ongoing £3.8m road resurfacing scheme on the city-bound section will see overnight and weekend closures in place until Monday November 25.

Weekend closures are taking place over the next eight consecutive weekends, commencing at 10pm tonight until 6am on Monday between the Tillysburn junction and the start of the M3. There will be weeknight overnight closures in operation for the duration of the scheme.

The majority of the scheme is expected to be completed ahead of the Christmas period when the road will remain open. However, more closures may be required in the new year.

In an update on Friday, the Department for Infrastructure said: During periods of closure a diversionary route will be clearly signed via Holywood Road, Newtownards Road and Middlepath Street. An alternative route will also be available via Holywood Exchange, Airport Road and Sydenham Road. Alternative routes will also be signed for cyclists and pedestrians.

“Some weekend and overnight lane closures will also be required on the country-bound lanes to ensure the safety of road workers and the travelling public while deep drainage work is carried out along the central reservation.

“This is a substantial scheme and the department is aware that projects of this scale will inevitably cause some disruption and delays, however all work has been carefully planned in order to minimise inconvenience to the public and complete the scheme in as short a period as possible.

“These essential works are part of our commitment to enhancing road safety, improving the driving experience and reducing long-term maintenance costs.

“Once completed, the resurfaced road will offer a smoother and more durable surface, benefiting thousands of daily commuters and supporting the long-term infrastructure of this key route.

“The department will also monitor progress throughout and take further mitigation measures to alleviate traffic congestion and delay where possible.”

Officials urged motorists to allow extra time for their journey, particularly if travelling to Belfast City Airport, and to follow the alternative routes which will be clearly signed on the approach to the works.
