<p>The latest estimate for the cost of the M56 junction 6-8 smart motorway scheme
is between £62m - £120m.</p><p> </p><p>The economic assessment for this scheme indicates
that it will lead to an overall reduction in collisions and casualties on the network
over the 60 year appraisal period. Traffic modelling indicates that the scheme will
divert vehicles from the surrounding road network, releasing the pressure on that
network. This will improve journey time reliability and contribute to a reduction
in the number of people killed and seriously injured (KSIs) on the road network as
a whole.</p><p> </p><p>This scheme is also expected to deliver journey time savings
in both directions.</p>
