On Oct. 28, Elon Musk shared a photo on Twitter showing the progress made on a Los Angeles tunnel constructed by his infrastructure and tunnel-drilling company, the Boring Company. In a separate Instagram post, Musk elaborated on how the underground tunnel would function: "It will work like a fast freeway, where electric skates carrying vehicles and people pods on the main artery travel at up to 150 mph, and the skates switch to side tunnels to exit and enter." According to the tweet, the tunnel has been dug a length of 500 feet so far, and is scheduled to reach a length of 2 miles in the next four months. [Twitter]

Students at the University of Virginia School of Architecture designed 3D-printed models of temporary installations inspired by the school's pavilions (famously designed by Thomas Jefferson) for the institution's bicentennial celebrations. Assembled in the school's fabrication lab, the end result was "a series of interlocking arches made of nontoxic, recyclable polypropylene plastic." [UVA]
