Murdo has said that "more people" will die on the A9 Perth to Inverness road until it is fully completed.
He was speaking following an update in Holyrood by Transport Minister Jenny Gilruth on the SNP Government's £3 billion project to dual the notorious road.
The Minister said it was now "simply not achievable" to meet the original intended target of 2025 to have the whole road fully dualled, citing a plethora of reasons for not doing so, including the war in Ukraine.
Commenting, Murdo Fraser MSP said: "We might have hoped for some positive news, some detail on a timetable for long-delayed completion. Instead, we had more bad news, with a further delay to the Tomatin to Moy stretch. We had no details on timescales, no hope, just empty words repeated over and over.
"More people will die this year, and next year, and the one after, as this SNP promise is not delivered."
Murdo continued: "The Transport Minister even had the nerve - on the day President Zelensky visited Britain - to blame Vladimir Putin's invasion of Ukraine for the SNP's inability to get this work done."
Thirteen people died on the A9 Perth to Inverness road last year - the highest number for 20 years.
