Overview

The Alex Fraser Bridge is long with a main span of . The towers are tall. It consists of seven lanes, three in each direction with the middle lane acting as a counterflow lane, and had a maximum speed limit of 90 km per hour until July 24, 2019 when the speed limit was lowered to 70 km/h to accommodate the additional counterflow lane. Upon opening in 1986, only four of the six available lanes were open. Cyclists and pedestrians share two narrow sidewalks one on each side. All six lanes opened in 1987 after traffic demand justified the need. The bridge's southern end is in North Delta and its northern end is on Delta's Annacis Island. Connections on its southern end lead to

Recent history

In December 2016, the Alex Fraser Bridge along with the Port Mann Bridge dropped "ice bombs," also called "slush bombs" on vehicles causing damage to windshields. The Alex Fraser has the cables along the sides of the driving lanes where as the Port Mann has them cross over-top of the driving lanes. In addition to 2016, this also happened on the Alex Fraser in 2005, 2008, and 2012. The Alex Fraser needed to be closed a few times during December 2016 due to the possibility of ice bombs; this caused major traffic problems in the region. To combat this issue, the BC Government announced that a heavy lift helicopter will be used to blow snow and ice off the cables to prevent it from accumulating and falling onto the cars below. An announcement was made on January 19, 2017, that a new seventh travel lane will be added on the bridge by slightly narrowing the existing lanes and removing the shoulders.
