Megaprojects almost always fall short of their promises—costing too much, delivering underwhelming benefits, or both. Yet...cities still fall for them, seduced by new technologies and the lure of the perfect fix. A mix of factors has given Seattle a particularly acute sense of angst. The project depends on a singular piece of engineering. And Bertha’s building a highway for cars in a city where workers overcrowd buses and commuters wrap themselves in waterproof everything to bike in the rain. — Bloomberg

Could the answer to London’s congestion be a network of subterranean cycleways? A new project from design firm Gensler suggests that maybe – just maybe – it might. Dubbed the London Underline, the project would turn London’s abandoned tube tunnels into living streets beneath the city. [...]

London Underline is being taken seriously enough in some quarters. Earlier this week, it won the Best Conceptual Project gong at the London Planning awards. — theguardian.com

The Second Avenue Subway is the stuff of legend in New York City, the locomotive who cried wolf. Plagued by funding shortages, the project has been stop-and-go since the 1920s. Now construction is back to go; in late September, the Metropolitan Transportation Authority (MTA) [...] requested $1.5 billion [...]. Michael Horodniceanu, head of construction for the MTA, has stated that the long-awaited line may be ready by 2029. In the meantime, the MTA is learning about, and acting on, geology. — cafe.com

A new engineering report assessing the damage caused to the Amtrak-owned Hudson River and East River tunnels in New York City by Superstorm Sandy in October 2012 recommends a phased process of maintenance works, which will require taking individual tunnel tubes out of service for extended periods. — railjournal.com

eric chavkin penned a review of "Glen Small: Recovery Room" an exhibit at Assembly in Los Angeles, organized and curated by Archinect's own Orhan Ayyüce. MightyMike (aka Michael Locke) commented "For local (Los Angeles) fans of Archinect, there's a wonderful example of Small's work in the Franklin Hills...the Leiberman House". For his part davidd felt "This review and Small's work seems to come from an ingroup/niche point of view".

Crossrail is not just about engineering: artists, designers and archaeologists are all involved in the £15bn new railway. As the amazing tunnel-boring machines approach halfway, Rowan Moore dons his hard hat and goes below — theguardian.com

The biggest public transit infrastructure effort in the US is almost completely invisible — unless you’re 160 feet underground. The East Side Access project will connect the Long Island Railroad to New York’s Grand Central Terminal via a massive tunnel under the East River. Actually, that tunnel was the easy part; it was started in 1969. The hard part? “We are building a brand-new railroad here,” says Michael Horodniceanu, president of Metropolitan Transit Authority Capital Construction. — wired.com
