According to a Border Roads Organisation (BRO) official, the restoration work has been started and the closed tube would reopen by tomorrow.
He said that a portion was damaged by it and after a joint inspection of experts from various departments, including geologists, the repair work was started this evening and is expected to be completed by tonight or by early morning tomorrow.
"We are hopeful of throwing the tube open for traffic anytime tomorrow," he said.
Senior police officers, including the Deputy Inspector General of Doda-Ramban-Kishtwar range, Rafiq-ul-Hassan, visited the spot to take stock of the situation.
The tunnel was constructed in the 1950's for round-the-year surface transport and has been operational since December 1956.
The tunnel was renovated by the BRO several times over the past decades to ensure it stays open.
