She will also inaugurate the multi-million Mati Public Market on the same day.
DPWH Southern Mindanao Regional Director Jerome dela Rosa on Monday said the bridge and approach construction is already complete and that it is just undergoing the curing period.
"Instead of the usual one month curing period, it will only be one week with the help of curing chemicals that will speed up the process," dela Rosa said.
The DPWH earlier intended to open the bridge simultaneously with the opening of classes Tuesday. Finishing touches, such as the installation of road signs and markers, are still on going.
Despite not being able to beat the class opening deadline, dela Rosa said, the construction of the bridge was completed 70 days earlier than scheduled.
The P206-million bridge was constructed by Ciriaco Construction for a duration of only 140 days.
The original Governor Generoso Bridge became impassable in April 2007 after one of its piers collapsed. The old bridge was then demolished, causing horrendous traffic jams.
