After over 20 full closures of eastbound I-210 Freeway lanes and hundreds of hours of construction over the last few months, crews are finally putting the finishing touches on the false-work for the I-210 Gold Line Bridge.
According to the Gold Line Construction Authority, the bridge is on track for completion this summer.
The temporary structure, which crosses the eastbound lanes of the I-210, was built to support the bridge superstructure during concrete placement. Because the falsework was erected over an active freeway, the work required more than 20 full closures of the eastbound freeway.
“Completion of false-work activity is a major milestone for the project,” said Gary Baker, Director of Construction for the Metro Gold Line Foothill Extension Construction Authority.
Construction of the false-work commenced in mid-February and required crews to work day and night shifts to install nearly 50 90-100 foot long beams (each weighing about 16 tons) across the eastbound lanes, along with hundreds of smaller beams to complete the structure. Over 300 feet of the 584-foot-long structure spans over the eastbound freeway.
“Although temporary, the false-work and subsequent form-work, play a critical role in achieving both the structural and aesthetic requirements of the design,” said Mr. Baker. “ Together, they must also support over 5,000 tons of concrete scheduled to be placed during an 18-hour period in May.”
The bridge project is on track for completion in late summer 2012, and is scheduled to be turned over to Foothill Transit Constructors - A Kiewit Parsons Joint Venture in December to begin installation of the track and other elements onto the bridge as part of the overall 11.5-mile Foothill Extension Alignment Project.
