Bay Bridge Fix Complete

The $25 million fix for the broken rods on the Bay Bridge’s east span was finally finished last week.  After only being in place for two weeks in March, 32 of the 96 galvanized steel rods used to hold down large seismic stabilizers on the east span snapped.  Caltrans determined the failure was caused by hydrogen that was able to penetrate the rods when they were standing in hydrogen rain-rich rainwater over a five-year period.

Workers Delicately Fix Leo Fridge Bridge

On September 25, the Wisconsin Department of Transportation closed the Leo Fridge Bridge near Green Bay after noticing a two-foot dip along the bridge.  Work began Tuesday to fix the sagging pavement by raising up the concrete and steel pilings.  The damaged section of the bridge weighs approximately 1,600 tons and thus requires a delicate and tedious process to make the bridge operational.

Construction Begins on Louvre Abu Dhabi Dome

The first piece of the 180-meter diameter Louvre Abu Dhabi dome was lifted into place on Wednesday.  The section was one of 85 preassembled structures needed to be raised in order to complete the dome.  The original plan to construct the museum dome called for a 1600-ton crane to lift each segment and connect them in a counter-clockwise direction.  However, that crane, nicknamed Megatron after the Transformers character, was delayed at another project is currently arriving in pieces at the construction site.  Instead, crane operators will use a 600-ton crane until the bigger model can be assembled to avoid any delays to the project.

The Cleveland National Forest Foundation, a small group of environmental advocates, filed a lawsuit against Caltrans on Wednesday over the plans to expand I-5 in the San Diego area.  The lawsuit claims the freeway expansion would lead to “an enormous surge in greenhouse gas emissions.”  Caltrans Final Environmental Impact Report, which was signed on October 23, 2013, states that the express lanes expansion project is the best way to serve the 300,000 daily trips along the freeway by 2030 as it has the least impact on natural resources, requires fewest property relocations, and has the lowest construction costs.

Westfield Group paid $800 million last week to buy 50% of the retail space in the new World Trade Center.  The company had previously purchased the other 50% of space for $600 million two years ago.  Westfield Group is a mall developer and operator and currently own shopping areas in London, San Fransisco, and Los Angeles.  The New York and New Jersey Port Authority owns the 16-acre World Trade Center site, and it will use part of the $1.4 billion in revenue from the sales to fund infrastructure in the region.  According to Port Authoirty chairman David Samson, Westfield’s investment will allow the Port authority to “refocus agency resources on our core transportation mission.”  No specific announcements have been made about where this funding will be used.
