Map with all coordinates: The Wisłostrada Tunnel is a road tunnel in Warsaw on the left bank of the Vistula in the course of the Vistula Boulevard .
history
The creation of the tunnels is connected with the construction of the Świętokrzyski Bridge . Since the bridge carriageway is close to the level of the carriageway of the Vistula boulevards, the traffic was moved in tunnels. The two tunnels were extended in the south direction to allow free access of the under the Vistula embankment city district Powiśle to create the bank of the Vistula. The busy traffic artery in the west-east direction (part of the road number 7 Gdansk-Krakow) cut off urban life from the river environment. Due to the tunneling, it was possible to end this situation, which was perceived as negative, and thus also to expand the area that could be used for urban development. The Copernicus Science Center was later built on part of the terrain above .
The construction costs amounted to about 210 million zlotys and thus around 30 million more than planned. The building project was partially criticized in public as unnecessary and inexpedient. The construction work lasted from April 2001 to August 2003. The opening had to be postponed several times because security measures were not met.
Both tunnels are equipped with three lanes each. The north-south tunnel is 930 meters long, the south-north tunnel 889 meters. They are equipped with a ventilation and smoke extraction system and a lighting system. There are bus stops with stairs in the middle of the tunnels. The area above the tunnels was greened and provided with walking paths.
In August 2012, the passage was closed because during construction work on the nearby “Powiśle” metro station, the earth masses collapsed, with the tunnel construction being undermined 11 meters deep. There was a risk of collapse. The road traffic was provisionally diverted and the cavity was filled with 5000 cubic meters of concrete; the tunnel was still closed in March 2013. The reopening took place on June 23, 2013, but only on two lanes.
