History

- On 5 October 2000, a civil house above the tunnel collapsed and the work stopped for one year.
- On 29 April 2005, the tunnel opened to traffic in the first step. Only small vehicles were allowed. A truck over 3500 kg in gross weights and a bus with 10 or more seats including the driver were prohibited while the authorities were not ready to deal with emergencies involving large vehicles.
