Gold Line Bridge About to be Built

Bridge detour: Looks like Foothill Boulevard is going to get pretty hairy.

The Gold Line Construction Authority will begin work on the 210 bridge (just west of the eastbound Santa Anita exit) in the coming weeks.

Here are sections from the press release:

The first step will be to prepare the site and provide access for the large construction equipment. The center median slope will be removed and a temporary retaining wall will be built to support the westbound lanes. This work will take approximately a month to complete. Once the retaining wall is installed, work will begin on the bridge's foundations.

Initial foundation work will consist of drilling several deep steel-reinforced concrete foundations (called piles) ranging in size from 3 to 11 feet in diameter and up to 110 feet below ground. Once the foundations are ready, construction of the bridge structure itself will begin in the Fall. To protect the freeway during the year-long construction, a temporary support (called falsework) will be installed across the eastbound freeway lanes.  

As construction begins, the Authority will be preparing bi-weekly construction notices as well as sending construction alerts when eastbound freeway closures are anticipated. Attached is the first bi-weekly notice (for June 27 through July 2011).
