Fund barriers and cameras to make bridges and motorways safer

The Government should fund higher barriers on bridges & cameras on access points that might alert emergency services when they see someone on a motorway bridge. Such bridges might have pedestrian gating access ways with a code that only emergency services have. Every day thousands of people experience a crisis so I believe that extra funding may help people a bit more. My family and I lost my sister to suicide and we don't want others to feel the grief we do.
