A28

Post by Mr C » Wed Dec 18, 2013 12:04

The road nerd in my needs to know about the start of the A28!

Is it at the clocktower roundabout with interchanging with the B2051 Marine Drive and the A254 running along Marine Gardens or does it start at the junction of the Marine Gardens and Belgrave Road with the A254 starting on Belgrave Rd? The sign on the A28 heading east towards the roundabout doesn't mention the A28 but that could simply be for economy of expression. The T junction where Belgrave Rd meets Marine Gardens has a sign saying that the road to the left is the A28 but as this is only a few yards from the roundabout this too could be for the sake of simplicity.

The Ordnance Survey says the latter.

Looking at older maps, this makes sense (see the 1:25000 layer on SABRE maps - the A254 and B2051 run along the High Street.

Of course, Advance Direction Signs treat Clocktower as one junction. The ones on the A28 and B2051 show the section of road between the C503 and the mini roundabout as narrower than the primary route approaching from. However, from the A254, the thick line starts on the ADS as you turn left, but is an older sign without the junction name. This, however, is merely dealing with primary status. OS goes with the A254's sign.

The Flamingo is considered to be on Marine Terrace, which is A28.

Sorry you've lost me! What is the C503. It isn't obvious from your post.

Look on Open Street Map. It's Marine Gardens. But I wanted to separate it from the bit of 'Marine Gardens' between the mini roundabout and Belgrave Road, as until I looked up the Flamingo's address, I didn't know that that bit of road wasn't Marine Gardens, but rather Marine Terrace.
