1987 borders. However, the new owner of the quarry, Italian company of "Adige Bitumi" continued the works, causing damages to the complex with the underground explosions. As Straževica was one of the first targets to be bombed in Serbia, one of the most attacked targets in general, and the first bombed location in Belgrade itself, there is a memorial on the hill, named "Herald of Straževica", commemorating the 1999 bombing. Glasnik monument In the summer of 2002, the monument was built on top of the hill, within the military complex. It was named "Glasnik" ("Herald"). The monument has the base in the shape of F 117 aircraft, surrounded by the large slabs of granite. At the bottom of the central part there is a relief, representing images of army officers Vlastimir Lazarević and Vladimir Vujović. They were repairing damaged antenna in 1999, trying to use the period after one wave of bombing, but the next wave ensued quickly killing them both. The sculpture was made by Slaviša Čeković. It is made of various metal debris, grenade shrapnel, parts of military antennae and pieces of metal constructions. On top of it is the antenna which is disconnected, but still operational, so it could be used eventually. Artistically, the sculpture is described as the "slightly tousled constructivism" with the touch of Vladimir Tatlin, while the style is characterized as Yves Tanguy's play on the unusual contraptions form. Transportation The first lane of the "Straževica tunnel", a long part of the projected Belgrade's outer beltway ( long Batajnica-Bubanj Potok section) was dug in January 2007 and the digging of the second lane was to begin soon. Digging of the tunnel originally began in 1992 (of the beltway itself in 1990), but was halted in 1996 and then resumed in September 2004. As the regulations of the European Union do not allow for highways to go right through the middle of the cities' urban tissue (which is the case with the Pan-European corridor X in Belgrade), Serbian government got 3 years to finish the beltway, but it wasn't finished in time. Since 2012, the right tube functioned as the two-way tunnel. Two sides of the left, long tube, were connected only on 9 June 2020. The deadline for the tube to become operational, so as the complete tunnel, was moved for the early 2022. On the western slopes of the hill, two elevated bridges
