New safety measures have been approved for a road previously listed among the most dangerous in the UK.
Slough Borough Council's cabinet green-lit the measures, including average speed checks and red-light cameras, as part of the A4 Safer Roads scheme.
The busy commuter route was identified by the government in 2016 as being in the country's top 50 most dangerous.
There were four fatal and 42 serious crashes on the road between 2016 and 2022.
The measures will be funded using £1.7m from the Department for Transport, and the cameras will be implemented jointly with Thames Valley Police.
Slough Borough Council transport lead Puja Bedi said: "The A4 is our main route through the town, and it is used by thousands of drivers every day.
"We are committed to making the route as safe as possible for everyone, as one death is one too many."
'Highest recorded risk'
Road surface treatments, traffic signal improvements, and work on pedestrian and cycle crossings are also among the planned measures.
Speed limits of 30mph are also set to be introduced in sections of the A4, after being approved in December 2022.
A government analysis further showed three fatal and 44 serious collisions on the route between 2011 and 2015.
A report by Slough council officers reads: "In 2016, the government established a Road Safety Fund as part of its ongoing investment in the national transport infrastructure.
"The aim of the funding was set out to provide financial resources to local authorities whose road network had the highest recorded risk of fatal and serious collisions.
"The A4 in Slough was identified with having a disproportionate number of casualties."
