An MSP has called for the Forth Road Bridge to be reopened in a bid to ease congestion until the “tourist boom” of the Queensferry Crossing passes.
Alex Cole-Hamilton has urged Transport Scotland to temporarily allow traffic to use the old bridge.
Both ends of the new £1.35bn bridge have experienced queues stretching for miles since its opening.
Transport Scotland said the build-up of traffic in the initial weeks of opening was to be expected.
Mr Cole-Hamilton, Edinburgh West MSP, said: “With such a fantastic structure there was always going to be an addition to traffic due to tourists wanting to see the new structure.
“However, it is clear that this is having a material impact on people’s livelihood with some commuters from Fife missing half a day of work due to the excessive build up of traffic.
“To help those who depend on free flowing traffic to on from Fife Transport Scotland should consider delaying the work to the Forth Road Bridge and keep it open until the ‘tourist boom’ of the new bridges passes.”
Later, on BBC Radio’s Good Morning Scotland programme, Mr Cole-Hamilton said: “My Call to Transport Scotland is to say ‘before you start digging up the old Forth Road Bridge for the much-needed repairs – which they say are going to take six to eight weeks to conclude – then let’s just make sure that this isn’t just small teething problems’.
“If there is a material problem with the road layout of the bridge we have a release valve in the form of the Forth Road Bridge.”
The new bridge across the Firth of Forth re-opened to vehicles on Thursday, ahead of the morning rush hour.
It had initially opened to traffic on 30 August 30 but was closed for celebrations between 1 and 6 September, with vehicles using the Forth Road Bridge instead.
A 40mph speed limit is in place on the approach roads and over the new crossing.
The Forth Road Bridge remains open to pedestrians and cyclists as work continues to make the final connections to the network.
‘Resilience and journey time’
Later in the year the Queensferry Crossing will become a motorway and the Forth Road Bridge will only be used by public transport and cyclists.
A Transport Scotland spokesman said: “We appreciate road users’ patience as the new road layout and crossing continues to bed in and recommend people plan their journeys in advance and check Traffic Scotland for the latest position on the roads before starting their journey.
“We have always said that even when the crossing becomes a fully operational motorway the main advantage will be its resilience and journey time reliability, as result of the introduction of hard shoulders, wind-shielding and a 70mph speed limit.
“It is a replacement for the Forth Road Bridge and as such does not increase capacity.
“The Forth Road Bridge will become a public transport corridor in the autumn, until then we are not going to get a true picture of operational performance.”
Transport Scotland officers are monitoring the new network to identify congestion points.
The Queen officially opened the bridge last Monday, following a series of events marking the opening of the structure, the longest three-tower, cable-stayed bridge in the world.
