Even Bruce Springsteen is singing about the 405 and this coming weekend’s Jamzilla, when the northbound lanes of the 405 will be closed or mostly closed for 80 hours. Above video from Springsteen’s show Saturday night in Perth, on the west coast of the AC/DC continent.

43 years ago Sunday: Sylmar quake topples freeway and prompts seismic retrofitting plan (Primary Resources) 

The Metro Library’s blog takes a good look back at the 6.6-quake in San Fernando on Feb. 9, 1974, that brought down freeway bridges, killed 49 in the VA Hospital in San Fernando and compromised many other structures. As a result, a new state law prohibited new development in earthquake fault zones. But 43 years hence, the state is still mapping those zones — the reason that Metro did extensive mapping work of its own when planning the Purple Line Extension in the Century City area.

A new OCTA video promoting the 91 Express Lanes that run between the 55 freeway and the Riverside County Line. The big news these days is that Riverside County is getting on board and adding the toll lanes between the county line and Riverside, a project scheduled to be complete in 2017. By most accounts, the aforementioned AC/DC song aptly describes this commute.

Bullet train ridership estimates up, cost estimates down in new business plan (L.A. Times)

The cost drops by $800 million to $67.6 billion to build the completely grade-separated line between San Francisco and Los Angeles. Meanwhile, ridership projections are up by 25 percent to 35 million in 2040.

Meanwhile, the project hopes to break ground this summer on the initial 29-mile segment of track near Fresno.

Sochi got the gold, bypassed village got the dust (New York Times)

The new road and railroad between Sochi and the Winter Olympics ski resort don’t include an exit or station, respectively, at a tiny mountain village of 200 that also took the brunt of highway and railroad construction. Residents hope that some of the Games’ money and excitement will trickle down to them, but that appears unlikely for now.
