Thanks Alex 2306, well not sure it is what I am looking for, But for sure the website seems pretty interesting, many thanks.
question is there a book with pictures?

If you are going to be in London, stop at Waterstone's Books on Bloomsbury St. They have at least two books on stone bridges.
They're everywhere - the bridges, I mean.
What parts of England are you going to? Perhaps we can tell you where to find them in those areas?

Anywhere, so far bridges are old ( construction until 18 century )
preference for Roman bridges and middle age bridges.
landscape surrounding prefers to town environment.

There are no surviving Roman bridges in Britain, just a handful of cases that we have some very ruined bits left over. There's a menu of Roman bridge articles linked by a menu at the bottom of this page. http://en.wikipedia.org/wiki/Roman_bridge There's a bridge called the Roman Bridge in the village my parents grew up in, Marple, but it's actually 18th century. The Roman Lakes in Marple are a landscaped feature of similar vintage.
I don't think we can say for certain which is the oldest surviving bridge in the country, because of the difficulty of dating early mediaeval bridges, but it is probably Tarr Steps in Somerset, which is roughly 1000 years old. The footbridge where the city wall goes over Bridgegate in Chester is datable to about 1120. Of vehicular bridges, I don't know, but Elvet Bridge in Durham is datable to 1160 which must be close if not it.
One category of mediaval bridge is the packhorse bridge, and there's a list of British examples of those here. http://en.wikipedia.org/wiki/Packhorse_bridge However the great majority are in fact post-mediaeval.
Mediaeval bridges in general are pretty thin on the ground. http://en.wikipedia.org/wiki/Thornborough,_Buckinghamshire has the only surviving mediaeval bridge in the whole county I live in.
This is the only fortified mediaeval bridge with intact fortification in the country.

There are four bridges with incorporated chapel in the country, one being http://en.wikipedia.org/wiki/St_Ives_Bridge, and it will lead to the others.
You should be able to find glossy picture books of old bridges fairly easily because I've seen them in bookshops, but the search facility on Amazon doesn't seem to want to make finding any very easy.

Swarkestone Bridge , a 13th century bridge near Derby, or the 14th century The Chapel of St. Mary on the Bridge in Derby might fit the bill.
Swarkestone Bridge is where Bonnie Prince Charlie turned round and headed for home
