Currently the tunnel, which connects the Istrian peninsula with the rest of mainland Croatia and spans slightly more than five kilometers, has only one tube consisting of two traffic lanes for east and west-bound traffic.
The European Commission has approved Croatia's plan to extend the concession agreement with Bina-Istra for the Istrian “Ypsilon” highway until 2039. This will allow for the construction of a second tube through the Učka Mountain, providing for separate tunnels for east and west-bound traffic, the renovation of an existing rest area and the construction of another access road leading to the tunnel. All told the investment stands at some 197 million Euros."
"This is a continuation of large scale investment into the transport infrastructure in Croatia. Currently we are investing somewhere in the vicinity of 25 billion Kuna, from the Pelješac Bridge to large scale rail road projects. This will obviously mark the coming period, the next four to five years," said Maritime Affairs, Transport and Infrastructure Minister Oleg Butković.
The Učka Tunnel is a toll tunnel on the A8 motorway in Croatia. Construction on the existing tunnel tube began in 1978 and it was opened for traffic on September 27th, 1981.
