|Route outline (key)|
The A270 is the former route of the A27 through Brighton and Hove, dating back to the construction of the bypass in the 1990s. The road's exact route has changed several times as various one-way systems have been constructed in Brighton.
It starts near the University of Sussex (at Falmer) as a slip road off the A27 going down to Coldean Lane. It's urban dual carriageway for a bit then becomes normal urban road full of buses heading south into Brighton called Lewes Road. It used to turn right into Upper Lewes Road (at the Vogue Gyratory) until the early 2000s when the council made that road a one way street.
The road now carries on into town and does things an A road really shouldn't, turning right into a small road and across a set of traffic lights into Cheapside, a tiny road that used to be (quite rightly!) unclassified. It then turns right again into New England Street, before turning left to rejoin the old A27 and become sensible again! Somewhere in all of this it crossed the A23.
It climbs a steep hill from under an ancient railway bridge (which as recently as the 1980s had a sign under it warning you that "British Railways are not responsible for damage caused by falling masonry from this bridge"), goes through Brighton and Hove and becomes a proper urban dual carriageway after crossing the A2023 in Hove. It then fluctuates between D2 and S4 before a huge roundabout just past Southwick provides access back onto the new A27.
The A270 is commonly known as a non-primary route, however before the by-pass was built it was a primary route. Nowadays signage is inconsistent (along with every sign in Brighton and Hove) and there is the occasional sign on the A270 which is in primary route colours. There is a higher concentration of these primary route signs on the diversion route of the Southwick Hill Tunnel, this may be done for traffic that would otherwise be following the primary route of the A27, including route confirmation signs.
