its the main railway bridge into the city, there was over a dozen police cars, about 7 fire engine's, a couple of ambulance's, the coast guard was there, in case he fell into the river, there was railtrack workers there aswell (the bridge is the main line in and out of the city) so the whole railtrack was down.
i dont know how long he was there or why, but definately look like he was drunk or high, as he was very unsteady, bare foot with no top on and just a pair of jeans on, he even walked to the bottom of the arch, thats when we thought he was coming down, but it was only to get a cigarette from a man trying to talk him down, he smolked it and wobbled back up the arch
