Yesterday Metro announced that, in January, the agency's board is expected to approve moving forward with Metro's 57/60 Freeway expansion project, located in Diamond Bar in east L.A. County.
At yesterday's meeting of the Measure M Independent Taxpayer Oversight Committee, staff announced that the board is scheduled to approve the LOP - the life of project budget - basically a go-ahead to spend hundreds of millions of dollars.
Streetsblog profiled the 57/60 widening mega-project earlier this year. Metro and Caltrans note that the intersection of the two freeways creates a “severe bottleneck,” “weaving conflicts,” “truck accidents,” and delays to commuters and freight. Metro and Caltrans assert that the widening project there will result in “Cleaner Air,” “Healthier Local Environment,” and “reducing traffic congestion.”
The 57/60 freeway widening project scope was approved in 2013, with a design tailored to serve the now-defunct NFL Grand Crossing Stadium proposed in the city of Industry.
add one new eastbound general purpose driving lane
add new flyover on- and off-ramps, including a new offramp through L.A. County’s Diamond Bar Golf Course.
widen the existing Grand Avenue bridge over the freeway (currently 72 feet wide, would be 118 feet)
Early construction activities are currently underway, including:
a $91 million shrinking of the public golf course, which looses five percent of its area
a $16.8 million expansion of Diamond Bar surface streets leading to the freeway
Those pre-construction phases are funded by Metro, but managed by the San Gabriel Valley Council of Governments. The SGVCOG will also manage the next phase of construction, which they put out to bid in October. According to the COG's notice to bidders, the next construction phase is anticipated to cost $270-275 million.
