The final phase of major runway renovation work will see a number of flights to Ljubljana Airport temporarily suspended in April.
With the first and second stages of construction work having been completed, the third and biggest stage will see traffic stop for a period of 15 days.
During the closure, which will be between April 7th and 21st, passengers can head to Maribor, Slovenia’s second city, where flights will continue to operate as normal.
Zmago Skobir, Ljubljana Airport’s chief executive officer, said the runway is the airport’s "key fixed asset".
"In deciding how to renovate the runway’s central section, our choice was between full and night-time-only closure," he commented.
"We concluded that full closure would mean lower risk, in terms of both safety and finance."
The runway is 3,300 metres long and 60 metres wide. Having been asphalted in 1978, it last received a thin coating in 1992.
A previous statement by the airport valued the cost of the upgrade work at EUR14 million (£12.5 million).
