Type 3-3 N/A
No. of Lanes: 3
Rail Code : 0000
There is a downstream check dam structure positioned near the oceans edge which tends to
maintain the water surface elevation in Buena Vista Lagoon relatively constant. Due to
this condition, the water level is 4 meters deep and typically in continual contact with
superstructure. Therefore the inspection has done from the surface only.
The easterly exterior girder has two horizontal moderate cracks (300mm long).
There is a missing post of easterly timber railing.
According the 2006 underwater inspection: The soffit areas of the structure are beginning
to exhibit notable areas of efflorescence, surface abrasion, delamination, minor
spalling, and minor concerns of exposed and corroding reinforcing steel.
MISCELLANEOUS
Next Underwater Inspection is in year 2011.
