6th October Bridge - 67,300 Feet
While the 6th October Bridge in Cairo is named after a single day – the outbreak of the October War in 1973 – it took more than 30 years to complete. Most of the 12.7-mile elevated highway passes over land, but the bridge does cross the Nile River twice, and with half a million people using it each day, it can sometimes take up to 45 minutes to stop-and-go from one end to the other.
