The Alba Party has called for a new motorway to be build to connect Edinburgh to the north-east of the country.
The capital city is connected to Glasgow via the M8, and the M90 runs to the north.
However, it is only 36 miles (58km) long and extends only as far as Perth.
Ash Regan of Alba is calling for a new stretch of motorway between Perth and Aberdeen which would bypass Dundee.

The current main route to the north-east, the A90, connects through the north of the city on the Kingsway.
The MSP is calling for a feasibility study to be carried out into the project, which she says would lead to safer and quicker journeys.
Most of Britain’s motorways were built during the 1960s and 1970s, but there have been extensions of existing routes in recent years.
From 2003 to 2005 the M77 was extended by nine miles to reach close to Kilmarnock, while the M74 was extended to meet the M8 between 2008 and 2011.
The M90 itself was extended southward to meet with the news Queensferry Crossing, having previously begun two miles north of the Forth Road Bridge.
Ms Regan said: “We shouldn’t rest on our laurels when it comes to continuously improving Scotland’s road network. We have witnessed through the delays to the A9 and A96 duelling projects what happens when an anti-road agenda is allowed to have influence on the Government.
“If the Scottish Greens had their way these projects would be scrapped and Scotland would never again build a new road.
“It is long past time to address the lack of motorways that connect the central belt to the North of Scotland. It takes nearly three hours at busy periods to drive from Edinburgh to Aberdeen. A new motorway would take emissions and congestion out of Dundee, it would make transport between Scotland’s capital and the North East much easier and everyone along the route would benefit from far safer travel.
“I would urge the Scottish Government to give this proposal serious consideration as part of this year’s programme for Government.”
Plans to create a bypass at Dundee have been floated in the past, and was cited in a 2008 transport report by the Scottish Government.
Dubbed the Dundee Northern Relief Road, ministers believed it would remove up to 50% of traffic from the Kingsway which runs through the city, also reducing emissions for those living close to it.
In 2022 though the Scottish Government published its second Strategic Transport Projects Review which instead focused on an “integrated transport plan” for the A90.
