Work to turn the next section of the M6 into a managed motorway starts today.
When complete it means the hard shoulder will be used between junctions 5 and 8 to reduce congestion at peak times.
The section of motorway includes Spaghetti Junction, and it will become the fourth managed motorway scheme in the West Midlands.
The works will link the previous parts of the road which have already been converted, between junctions 4 and 5 and junctions 8 to 10a.
It's hoped when finished it will help traffic flow more freely by using variable speed limits and opening up the hard shoulder at the busiest times of day.
Construction firm Carillion are carrying out the works, which they say are challenging because much of the carriageway between junctions 5 and 8 are elevated, including the complexities of the infamous Spaghetti Junction.
The work is expected to cost £126 million and is due to be completed in 2014.
