Hyperloop Transportation Technologies, Los Angeles, announced a partnership with the Los Angeles design firm AECOM for help constructing a five-mile prototype track to test the principle of the hyperloop: a transit system that shoots passenger-filled capsules at hundreds of miles an hour over long distances through low-pressure tubes.
Pile-driving adjacent to an Interstate 65 bridge near Lafayette, Ind., appears to have started a subterranean chain reaction that left one of the structure's riverbank piers skewed out of alignment, forcing a 37-mile closure of the northbound lanes that could extend into mid-September.

The 7-MW component is for a 14-MW wind farm under construction in the Onahama Port test area of Fukushima.The turbine stands 105 meters from sea level to the rotor center and 188.5
Lerner and Associates Planned 60-acre urban park in commercial center would channel traffic into underground tunnel. An average of 750,000 vehicles drive every day on Israel's most heavily used freeway. Tel Aviv city officials have given initial approval to an estimated $500-million plan to add a 60-acre roof park over the central segment of the Ayalon Freeway, the busiest transportation artery and densest infrastructure corridor in Israel.The plan calls for covering a 2-kilometer-long by 100-meter-wide section with a grassy roof, with traffic flowing through a tunnel underneath.While a freeway roof has long been eyed by city officials, last month's approval

The Federal Highway Administration provided $2 million in emergency-relief funds to repair a California bridge that partially collapsed after the foundation washed away under an abutment.A heavy rainfall on July 19 washed away the abutment at the eastern end of the Tex Wash Bridge near Desert Center, Calif., which carries eastbound traffic on Interstate 10, the main link from Southern California to Arizona. The westbound bridge also was damaged but still standing, and traffic flowed over it in both directions after foundation repairs.The

On July 23, the cutterhead of a tunnel-boring machine, dubbed "Lady Bird," that is mining the first section of one of several tunnels being built to improve the water quality of the Anacostia River, was lifted out of a shaft near a pumping station in Washington, D.C., after completing its mission.Manufactured in Germany by Herrenknect, the TBM removed approximately 1.2 million tons of material from the four-and-a-half-mile tunnel.The tunnels are being built to reduce stormwater and combined-sewer overflows.
