Sydenham Bypass closed from
10pm 31/01/25 to 6am 03/02/25
The Sydenham Bypass will be closed CITYBOUND ONLY from 10pm Friday (31st) until 6am Monday (3rd) as part of a resurfacing scheme.
NO ACCESS TO M3/WESTLINK FROM DEE STREET, only access towards City Airport/Tillysburn/Bangor direction. (I.e. no right turn to M3)
Bangor-bound is down to one lane before Dee Street which may lead to tailbacks on to M3 Lagan Bridge
Allow extra time for travel to Belfast City Airport & The SSE Arena, Belfast.
If you are diverting along Newtownards Road, avoid using Dee Street to get on to Sydenham Bypass, as traffic from Airport Road has priority at the roundabout which causes added congestion to the Dee Street/Mersey Street area.
Also remember that Holywood Exchange will be particularly awkward to get out of, especially for those on the Decathlon down to IKEA side of the retail park.
This is due to DfI not wanting to add temporary traffic control measures – and the roundabout having priority for diverting traffic.
Airport Road diversion going to:
•Belfast City Airport – if Dee Street junction is busy, head down Sydenham Road to junction before SSE Arena/Titanic Quarter, turn left and left again back on the Sydenham Bypass.
•M3 Flyover – use Sydenham Road, pass the SSE Arena, and left at the Middlepath Street lights.
•Belfast City Centre – use Sydenham Road, pass SSE Arena and use the Station Street Flyover to get to Queen's Bridge.
Holywood Road/Newtownards Road diversion:
•Belfast City Airport: Follow to Middlepath Street, and turn right before the M3 on-slip.
•M3: Follow to Middlepath Street, join M3 at on-slip
•Belfast City Centre:
Use Albertbridge Road (passing Lanyon Place/St George's Market) or follow diversion Middlepath Street, continue to Bridge End, Queen's Bridge.
