The establishment of the tram line was complicated by the need to have it pass underneath the railway and Suur-Sõjamäe streets. The builder faced real challenges of how to ensure that trains could continue in operation during construction. The novel solution and the heightened safety requirements made it time-consuming to execute the project, yet the result is that Tallinn has its first tram tunnel. During establishment of the 150-metre-long enclosed part of the tunnel and the 125 metres of ramp, about 10,000 m³ of limestone pulverized by hydraulic jackhammers and 6,000 m³ of soil were removed. A total of approximately 1,000 m³ of concrete was poured, plus tram tracks and load-bearing structures totalling close to 700 m³ in volume.
