This week we're heading to Chicago, USA to look at the SECRET $4BN tunnel network under the metropolis, AKA: the Tunnel and Reservoir Project (TARP) - this massive 175-kilometre tunnel is quietly saving the windy city.Later in the show, we talk about the £3.5BN new district that's been proposed for London. Extending across a 20 hectare site in the Royal Docks to the east of the city centre and opposite the ExCel centre, this proposal looks to transform a whole area of the UK's capital - including the derelict Millennium Mills. Also, Saudi Arabia appears to have started construction work on Trojena — a vast development in the desert mountains that hopes to host the 2029 Asian Winter Games. Lastly, we chat about Chengdu's dramatic new Science Fiction Museum that's under-construction and set to host the international Worldcon event later this year. Conceived by Zaha Hadid Architects, the 59,000 square metre complex is designed to appear like a "star cloud" floating over the surrounding Jingrong Lake. It looks immense.We end the show with a lovely email sent in from Ludvig Ring, who seems to be our biggest fan yet…? Maybe? We also read out a lovely Apple Podcasts review.Get in touch!
