Dangerous underpass, completely neglected

The underpass between the Hilton hotel and the Castle is in a terrible state. There is only one working light, it’s almost pitch black even in the day time, there is glass all over the floor, the smell is horrendous, there is graffiti and rubbish everywhere, it feels intimidating and dangerous. It would be great if the Council could prioritise improving this underpass, or perhaps consider putting a crossing at street level? Why are pedestrians forced to go out of their way to use such a horrible underpass just to cross the road safely, while cars can drive past unimpeded overhead? No wonder people prefer to stay in their cars, as opposed to walking. I really hope the Council can take action to tackle this eyesore.
