Large Design-Bid-Build Projects?

I'm currently researching procurement methods for transportation construction projects (such as highways, bridges, etc.), specifically comparing Design-Bid-Build (DBB) and Design-Build (DB). As construction values increase, there’s a noticeable trend toward more DB contracts and delivery methods. The typical reasons stated for preferring DB are its speed, single point of accountability, fixed costs, and the potential for innovation. However, I’d like to dive deeper and explore large-scale projects delivered using DBB. The largest DBB project I’ve personally been involved in was \~$125M, and it was highly successful. What other personal examples come to mind? Also, does anyone know of public databases that track this kind of information? I find it interesting because many of these are counterfactual problems, where you can't go back and redo things for comparison.
