The Grič Tunnel is a four-lane tunnel in Lika region of Croatia, an integral part of the A1 motorway located between Otočac and Ličko Lešće interchanges.

The tunnel consists of two tubes, excavated in 2003 and opened for traffic in 2004.

0.9 metres (3.0 ft) wide inspection sidewalks are present in both of the tunnel tubes.

[6] Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the motorway carries substantial tourist traffic to the Dalmatian Adriatic resorts.

The traffic count is performed using analysis of toll ticket sales.
