things are that bad between you and wandsworth? things are not bad between us and wandsworth. the residential streets of pimlico. there are now 33 bridges across the thames from the tower of london to hampton court. i have very great pleasure in declaring this bridge open to the public. but it would be a mistake to think their construction has always passed smoothly. peter matthews, who's an expert on their history, says a row over a planned new bridge is nothing new for london. certainly not, i mean the most famous one was westminster bridge, it took over 30 years for permission for that to be built, because the city of london objected because they owned london bridge and they had tolls to collect and they didn't want to lose it to westminster bridge. at the moment, the newest footbridge to be found on the thames is quite a few miles upriver, near maidenhead. but its designer, martin knight, who's a specialist in bridges, says if the right locations can be found in london, there's a bold new future ahead. in the future, i can imagine we are going to have 3d printed bridges —
