Equipment was mobilized this week for the upcoming foundation work on the bridge to carry the Metro Gold Line Foothill Extension light rail line from the median of the I-210 Foothill freeway over the eastbound lanes.
A large drill rig and crane have been trucked in and are being assembled on the south side of the eastbound I-210 Freeway. This is the location of the first of three 110-foot deep, 11-foot in diameter foundations to be drilled over the next four weeks. The other two are located in the center median of the freeway. Each foundation will take approximately six days to drill and cast. The first foundation is anticipated to be drilled next week, followed by the installation of the reinforcing steel cage, concrete placement and testing the following week.
This schedule is dependent on receiving final approval from Caltrans this week. During these activities, partial and full eastbound lane closures are planned (full closures occur late at night to minimize traffic delays).
