NEXT STOP: THE LOS ANGELES METRO RAIL

The article describes the design aspects and budget constraints that have slowed construction of the Los Angeles subway. Gassy tunnels and the risk of building settlement in the densely populated metropolis have caused problems. Also ground water severely contaminated with hydrogen sulfide took designers by surprise and forced construction of an on-site wastewater treatment plant. Engineers had also to design for the likelihood of an earthquake, even though there are no seismic codes in Califronia governing underground construction.
