Every weekday, more than 80,000 vehicles cross the River Mersey using the Silver Jubilee Bridge, overshadowed by its 87-metre high, 330-metre wide arch. Opened in 1961, the now Grade II-listed structure was designed to cope with only one-tenth of that number of cars, and the resulting traffic jams has reduced the journey between Runcorn and Widnes to a snail's pace.
