These projects are built within budget and on schedule, overcome unique challenges or embrace innovation – or any combination. This y te Link Exten- sion for Sound Transit in Seattle. The te Link project involves the construction of 4.3 miles of twin-track railway from a new elevated station near 1st Av eet to the existing University of Washington Sta te Link project includes 3.6 miles of twin-track tunnels and two new underground stations, all built within a densely populated area as well as under the university itself. The notoriously difficult ground in the region came in to the play, as usual, as did restrictions on tunneling under campus and its world-class research facilities. The joint venture of Jay Dee/ Coluc warded the design-bid-build contract for $440 million in 2013, and recently finished c - gate Link is scheduled for revenue service in 2023. Interestingly as te Link was under construction in 2016, Seattle voters approved ST3, a ballot measure that provides $54 billion to expand and improve the region's transportation, in- cluding an additional 62 miles of light rail. Plans going forward include the Ballard Link Extension that may include a new 3-mile long tunnel under downtown Seattle, parallel to the existing downtown tunnel. This surge in demand for sustainable, reliable and efficient transportation options are being seen across the country and across the glob oronto and Los Angeles are in the midst of huge investments in new rail infrastructure, as are areas lik rancisco/San Jose, Vancouver, eal, Calgary. According to the statistics from the International Tunnelling Association (ITA), the demand for tunnels in general is stag- gering. Global output for tunnels in 2016 was €86 billion euros (approximately $100 billion USD), with an average 5,200 km (3,200 miles) of constructed tunnels per year. The yearly aver- age growth rate in tunneling is 7%, double that of the global con- struction market at large. What more, interesting is building in non-traditional transpor- tation systems that could drive demand even higher. Studies are underway for a 60-km maglev train between Washington, D.C., and Baltimore with more than 75 percent of the alignment under- ground, and Chicago has awarded a contract to The Boring Com- pany for the construction of an 18-mile high-speed link between downtown Chicago and O'Hare airport. Similarly, interest is building in hyperloop systems elsewhere in the United States, as well as in Europ Speaking at the 1st annual HARP International Conference on Hyperloop Transportation and Related Technologies July 23-24 in Los Angeles, Brad Swartzwelter of Amtrak said the ultimate key to the success of hyperloop systems is tunneling. Tunnels allow the hyperloops to be straight – both in terms of line and grade – and provide greater protection from compet- ing transportation systems/utilities, the elements and terrorism. From a financial standpoint, tunnels may have a higher initial cost, but the total construction and land cost would be cheaper than the surface option in the long run. "As the hyperloop systems start to get built, we could see the greatest expansion of tunnel construction ever seen," he said. While there are still issues to be resolved – technically, legally, politically, financially – high speed, safe and efficient transporta- tion systems are certainly appealing. The appeal becomes even greater when the systems are underground, leaving surface space untouched.
