"Extending the M74 motorway above Glasgow's existing road network in 2011 has not affected the number or severity of road traffic accidents in the area. While the number of accidents fell by around 50% between 1997 and 2014, similar reductions were seen across other areas not affected by the motorway, suggesting a general trend of improved road safety."--Provided by publisher.
