Ensuring a Safe Reopening
Following extensive tests conducted by Caltrans, the concrete and temporary supports have undergone testing to ensure that the bridge can bear weight safely while construction continues.
Tests include:
- Core sample tests of the concrete for strength certified by an independent testing lab.
The results met or exceeded national standards.
- Steel rebar tests to make sure safety requirements are certified by an independent testing lab.
The results met or exceeded national standards.
- Chemical tests of the concrete columns to check for any long-term deterioration.
The results showed the 10 was safe for drivers.
In addition to repairing the columns, engineers will fortify the bridge with additional steel reinforcements to make it stronger than it was before the fire last week.
The freeway will be continuously monitored to ensure it remains safe for commuters by installing devices to monitor any structural shifts or movements by the freeway during use. Manual daily surveys will also be conducted to verify the accuracy of the electronic measurements.
