The Goverment has given the go-ahead to award the contract for a notoriously dangerous section of road in Co Sligo.
The N4 between Collooney and Castlebaldwin, described by Transport Minister Shane Ross as a notoriously dangerous stretch of road, is to undergo a €150 million upgrade.
Minister Ross has announced that the 15km section of road is to be rebuilt to a modern standard.
The existing road has seen 9 fatal road collision, 10 serious accidents and over 80 minor accidents over the past 20 years.
Following a fatality in 2015, the section of road was described by the Sligo Coroner as "possibly the worst road in Ireland".
The Collooney to Castlebaldwin road is to be upgraded to a Type 2 dual carriageway.
Transport Infrastructure Ireland says it will work with Sligo County Council and the contractor Roadbridge to complete the project in 2021.
