Just to confirm- you crossed the bridge?!!
Joking aside - I'd always be more scared of a new bridge than an old one. If it's been around for 20 years I think it can live a day more. If it's been around for a week, it hasn't exactly earned my trust yet :)
Hahaha true! But how does it earn your trust? By you crossing it or by others crossing it? Does it matter how long it has been up if it is your first crossing that earns your trust?
