Closures
On 6 February 2009, the bridge was closed by weather for the first time since its opening after three vehicles were struck by falling ice, damaging windscreens. Bad weather, and again falling ice, repeated this in December 2009. Temporary speed limits are put in place due to heavy wind or fog, with drivers informed of this by the electronic signs. Owing to the more advanced aerodynamic design of the later bridge, the Second Crossing is far less prone to such restrictions owing to crosswinds than the first Severn Bridge.
