Police are urging drivers to take extra care on the roads after prolonged downpours led to a number of landslides.
Heavy rains battered the West of Scotland and Highlands overnight leading to landlips on the A835 Inverness to Ullapool and the A83 Rest and Be Thankful in Argyll and Bute.
The A890 between Ardnarff and Strathcarron was also closed to all traffic and pedestrians due to a large landslide.
Police Scotland said there was a danger of falling rocks and motorists were advised to use the A87 as an alternative route between Kyle and Inverness.
A police statement said: "Police Scotland are advising motorists to take extra care when travelling on roads throughout the Highlands.
"Heavy rain has continued to affect roads throughout the night and the early morning.
"Motorists are being advised to allow extra time when planning their journey."
Conditions began to improve throughout the morning and the Met Office amber and yellow warnings, which have been in place, have now expired as the weather front moves south.
The Scottish Government said it is monitoring the situation closely and the partnership approach to ongoing incidents continues, with an average of 227mm, almost nine inches, of rain falling in the North West Highlands since Friday.
It is estimated that about 150 tonnes of material has come away from the hillside at the Rest and Be Thankful and the Old Military Road diversion route is being set up for use in tandem with a clear-up operation, to allow people to continue to travel through Argyll and Bute.
Elsewhere, there were some flooding issues in Oban and on local roads and in Greenock, Inverclyde, a diversion has been put in place as a result of flooding on the A8.
Transport minister Keith Brown said: "We are seeing a generally improving situation and this will continue throughout the day.
"The main issue is the A83 where there has been a large landslip at the Rest and Be Thankful and two smaller events at either side.
"Our teams are working hard to get the Old Military Road diversion route up and running, and clear debris from the two less serious incidents at Glen Kinglas and Ardgarten, at either end of the Rest, to allow the alternative route to be used.
"This will keep Argyll and Bute open for business with the clear-up at the RaBT under way.
"A substantial amount of rock and mud has been dislodged from the hillside above the Rest and Be Thankful due to the significant rainfall in the last few days and while some of it has reached the road, a great deal of the debris has been caught by the netting that Transport Scotland has installed as part of its landslide mitigation measures in the area.
"The Scottish Government is intent on finding solutions to keep the A83 open and operational, and has already invested nearly £8 million on the A83 around the Rest and Be Thankful.
"Our landslide mitigation work at Glen Kinglas continues, with the aim of having the first stage of the work completed in advance of the summer.
"We are working closely with our stakeholders to give people the latest information on what is happening and I would urge those travelling in the area to use the Traffic Scotland website and Twitter feed for updates.
"While the weather will be better over the next few days, we are expecting more wet and windy conditions towards the end of the week.
"Our Ready for Winter campaign highlights how the public can be prepared for weather events and we would encourage everyone to be as prepared as they can be, be aware of where to get help and look out for those nearby who may not be as able to cope with extreme weather events."
Environment minister Paul Wheelhouse, who also attended the SGoRR meeting, said: "Although the Met Office warnings have now expired, many areas have seen heavy rain in the last few days and localised flooding later today remains possible - especially in the Inverness area.
"We will continue to monitor the situation and with more rain expected later this week I would ask everyone to remain vigilant
"I'd encourage everyone to regularly check with the Sepa floodline website for updates and warnings. If you sign up you can also receive floodline warnings directly to your mobile phone."
