Residents living on one of the UK's most polluted roads could be offered 150% of the value of their homes, so they can be demolished.
Hafod-Yr-Ynys Road in Caerphilly County, is described as one of the UK's worst polluted areas outside London with the levels of pollution far exceeding World Health Organisation guidelines.
Last year, it was revealed there were 69 units of nitrogen dioxide in the air. The legal unit is 40.
"The front of our houses look so dirty - they're like slums. We've worked hard and spent thousands - but we're just giving up", resident Martin Brown told ITV News in 2018.
The Welsh Government told the council in February 2018 it needed to work out what to do about the pollution problem. A compulsory purchase of the south side of the street was one of the options given to the council as well as introducing banning lorries between peak times, and a clean air zone.
Mr Brown said he also had serious concerns about the safety of residents, due to the volume and speed of traffic in the area.
"If they do knock them down, which I wish they would. At least we could go somewhere where we're not in fear of our lives. It's frightening"
The A472 between Pontypool and Newbridge sees more than 21,000 vehicles pass through it every day.
The council is due to meet next week and will decide whether to give the go-ahead to the plans.
