A 20-metre-high and 50-metre-wide bridge will tower over the M6 in Birmingham as tyre company Dunlop Motorsport plans to pay homage to its original factory, making rubber since 1916. Set to cost £5 million, the Dunlop Centenary Bridge is due to be completed by 2016, and will replicate the famous bridges seen on display by the manufacturer at racing circuits such as the Cirque de la Sarthe and Bathurst.
