April of 2010 and mentioned that the bridge had later been retrofitted with steel column casings. However, when I returned this week there were still no column casings! The bridge was constructed in 1971 and improved in 1996, but the improvements apparently didn't include a column casing (it could have been a concrete casing). It will be interesting to see how this oddly-shaped bent performs during the next big earthquake. This area of Contra Costa County is crossed with many faults, including the Franklin Fault that crosses under the adjacent 24/680 Interchange that we will be studying tomorrow.
