It can be fast to replace a deck and with no sub-structure (foundation and pier) work.
Demolition and haul-away the old deck is challenging and time consuming.

It's still not easy. Cheers! Good to have the big machine working on other interchanges in BJ, hopefully same way. BJ has over 45 such interchanges to be replaced soon.

It is also easier on the type of interchange as SanYuan, flat and with at- grade ramp intersections for by-passing. Flat under-pass has flooding problem, and intersections will have traffic conflicts during normal operation.
