Everyone is pissed.
In Mexico City, many people who travel on the subway system blame authorities for the many broken escalators at train stops. Metro officials blame something else: “vast amounts of pee,” reports A-Pee.
Nobody's clear exactly how it happens, but human urine, in really large amounts, is “penetrating and corroding the drive wheels and mechanisms of the escalators that carry riders up from underground stations,” AP reports:
In a list published Tuesday, the Metro system listed “corrosion due to urine” as one of the top five causes of escalator breakdowns. Fermin Ramirez, the system’s assistant manager for rails and facilities, said riders appear to be urinating on escalators at off-peak hours and lightly used stations, “even though it seems hard to believe.”
“When we open up escalators for maintenance, there is always urine,” Ramirez said. Most stations have no public bathroom facilities, a fact Twitter users were quick to point out, noting there are not even any pay toilets.
Of the system’s 467 escalators, 22 are out of service on any given day.
The biggest problem, subway authorities admit, is that the many escalators are old, or have been damaged by rough use.
Mexico city plans to replace about 55 escalators over the next two years.

Our cities' sewers are some of the most incredible structures in the built environment. In a new book, "An Underground Guide to Sewers: or: Down, Through and Out in Paris, London, New York, &c." historian Stephen Halliday explores the systems (and people) that deal with our shit so we don't have to. From the book description:
Halliday begins with sanitation in the ancient cities of Mesopotamia, Greece, and Imperial Rome, and continues with medieval waterways (also known as “sewage in the street”); the civil engineers and urban planners of the industrial age, as seen in Liverpool, Boston, Paris, London, and Hamburg; and, finally, the biochemical transformations of the modern city. The narrative is illustrated generously with photographs, both old and new, and by archival plans, blueprints, and color maps tracing the development of complex sewage systems in twenty cities. The photographs document construction feats, various heroics and disasters, and ingenious innovations; new photography from an urban exploration collective offers edgy takes on subterranean networks in cities including Montreal, Paris, London, Berlin, and Prague.

[We're delighted to have Rosemary Frei back with us, this time reporting on a global transformation: once, infrastructure was created efficiently with cheap central bank funding and now it's done with public-private partnerships, at much higher price-tags, creating massive transfers from taxpayers to the biggest businesses and private equity funds in the world. As we get ready for huge infrastructure buildouts to address climate change, the super-rich stand to reap trillions – money we could be spending on saving our lives and even our planet. -Cory]
Trillions of dollars are being plowed into high-tech hospitals, zero-emission public transit and other megaprojects around the globe. Shiny new infrastructure is popping up virtually everywhere, from Australia to Appalachia. Read the rest

From Practical Engineering:
Traffic management in dense urban areas is an extremely complex problem with a host of conflicting goals and challenges. One of the most fundamental of those challenges happens at an intersection, where multiple streams of traffic - including vehicles, bikes and pedestrians - need to safely, and with any luck, efficiently, cross each others’ paths. However we accommodate it now or in future, traffic will continue to be one of the biggest challenges in our urban areas and traffic signals will continue to be one of its solutions.Read the rest
James "New Aesthetic" Bridle (previously) is several kinds of provocateur and artist (who can forget his autonomous vehicle trap, to say nothing of his groundbreaking research on the violent Youtube Kids spammers who came to dominate the platform with hour+ long cartoons depicting cartoon characters barfing and murdering all over each other?).

More than a decade of foot-dragging on fiber rollout has left millions of Americans dependent on taxpayer-funded copper-line infrastructure for landlines and DSL, but it's not like the carriers are plowing their no-fiber savings into copper maintenance, instead, as a report released by Minnesota Attorney General Lori Swanson details, incumbent telcos are literally leaving their infrastructure to rot: wires are draped across customers' lawns (and over their propane tanks!), boxes containing key network gear are left smashed and rusting, and carriers' poles and other furniture are literally propped up with 2x4s, or have random logs placed against their wires to hold them in place.

Geographic information systems used to be 2-D maps, but new AR technologies are letting users see where pipes and other underground infrastructure is through augmented reality .
Brief video showcasing a few features of the vGIS Utilities system (http://www.vgis.io/). vGIS Utilities is the most advanced augmented reality solution for GIS designed specifically with utilities, municipalities and GIS service providers in mind. The system connects to Esri ArcGIS to seamlessly convert traditional 2D GIS data into powerful, accurate and stable 3D visuals.
vGIS is the only system that supports the full spectrum of technologies - augmented reality (Android and iOS), mixed reality (HoloLens) and virtual reality.
The system is deployed in at over 40 sites across the world to bring real-life benefits to municipalities, utilities, locate service providers and multiple other organizations.
Bernie Sanders has a plan to solve America's wage stagnation and its long-neglected infrastructure: tax the super-rich and massively profitable corporations, then use the money to fix the multi-trillion-dollar infrastructure overhand left behind by decades of neglect, and hire Americans at $15/hour, plus full healthcare, to do the work.

US infrastructure spending as a proportion of GDP is at a low not seen since WWII, and that's why America's bridges, dams, roads, power plants and other key infrastructure are such easy fodder for Hurricane Harvey (and the impending Irma devastation). Trump's plan for infrastructure spending is a "ludicrous patchwork of tax breaks and privatizations" that will do nothing to solve the problem. Read the rest
