Work is proceeding on the “Iconic Bridge” that will carry the Gold Line tracks over the eastbound lanes of the 210 freeway in Arcadia.

The latest, shown above: crews are installing the first of 18 “small diameter cast-in-drill-hole piles” that will be the foundation for the abutment on the freeway’s south side.

The Foothill Extension will run for 11.5 miles from the Gold Line’s current terminus in Pasadena to the Azusa/Glendora border. The project is funded by the Measure R sales tax increase approved by L.A. County voters in 2008.
