Plans for an almost £2 million transformation of a road in the South Hams could be approved later.
The A3121 connects the A379 west of Modbury to Ermington and the A38 east of Ivybridge.
In 2016 the nine kilometre road was listed as one of the 50 most dangerous in the country in a Goverment report.
Between 2012 and 2016 it saw 31 accidents - including six fatal ones.
Devon County Council is today expected to vote to make 12 changes to the route.
It would be paid for through a Government fund which was set up to help transform dangerous roads.
The report identified two roads in Devon in the national list of 50 - the A3121 in the South Hams and the A3123 in North Devon.
A Council report says: "A 'Safer Roads Fund' bid was submitted to DfT for both the A3121 and the A3123.
"Devon County Council was subsequently awarded £1,900,000 for the A3121 and £2,200,000 for the A3123.
"The proposal is to implement up to twelve road safety improvement schemes along the 9km length of the A3121, the twelve combined comprising a ‘whole route’ intervention.
"This is in line with the original grant requirements imposed by DfT and Devon’s Road Safety Vision that every route and every mode should be available to everyone, free from risk or fear of harm.
"The collision analysis identified future risk as being, at least in part, related to the presence of junctions and associated inter-vehicle conflict."
