I’m curious why the current bridge needs replacing? Is it failing?
Maybe this will help: “The project is needed due to chloride intrusion in the concrete of Limekiln Creek Bridge, which was confirmed with concrete core testing and inspections by Caltrans’ Structure Maintenance and Investigations Team in 2012. There has been irreversible damage to the superstructure and substructure elements caused by chloride intrusion from pervasive salt-laden fog. This has resulted in frequent concrete cracking and reinforced steel and cable corrosion. There have also been recurring slope stability problems at the north abutment caused by powerful waves. There have been attempts to stabilize this slope; however, it is not possible to permanently stabilize it. There is a permit requirement (Coastal Development Permit 3-09-020) from the California Coastal Commission to remove the existing slope armoring. As a result of these issues, the need for replacing the existing bridge was identified by the Structure Maintenance and Investigations peer review committee in its October 2012 meeting.” –CalTrans
I’m curious about how actual FOG becomes salt-laden. Salt in ultra-giant aerosols kicked up by wind and waver action maybe, but in true fog?
So what is the new bridge railing going to look like?
1. What will the new bridge railing look like? Ref. Garrapata Creek Bridge railing controversy.
2. Regarding the comment with more details – if the need to replace the bridge was documented in October 2012, what has taken so long? Is it safe?
Oregon has had great success with what they are doing to protect their historic concrete bridge and rails against corrosion, amazing!
