Most drivers spend many hours of our lives on motorways - but the gangs who carry out the roadworks risk their lives every day.
In fact, more than 300 have been killed in the last five years.
The dangers can be worse at night and, of course, when drivers speed or use mobile phones.
Roadworks on the M60 around Manchester are a particular nightmare for motorists at the moment.
The work will make it a smart motorway able to monitor a variety of different speed limits.
