Waikaumalo Bridge

I'm not sure which bridge this is - the old or new Mamalahoa Rd.

Hawaii Belt Road is also called Mamalahoa and in general it follows the HCR railroad alignment which was converted to automobile use in the late 1940's. This is the new one. The old Mamalahoa road is the one that winds it's way down at each river and stream crossing where the former railroad alignment uses tall bridges and trestles.

Before I moved the marker, it was a couple miles out to sea. I moved it to the old Mamalahoa road crossing because that seems to fit the date better. But the NBI length and span info seems to match the new road. But the NBI also lists a steel stringer crossing this stream for Hawaii Belt Rd.

Anyway, I'm guessing this is the one on the old road. And I'm noting it here for future editors.
