| Description | The Lions' Gate Suspension Bridge arches 60 meters above Vancouver's First Narrows, connecting communities on both sides of Burrard Inlet. More than 60 years of constant traffic and corrosive deicing treatments left the steel and concrete roadway in need of improvements. A distinguished landmark, it has average daily traffic of between 60,000 and 70,000 vehicles. Beginning in 1999, a rehabilitation project included replacement of the three-lane bridge deck and trusses encompassing widened lanes for traffic, widened sidewalks for cyclists and pedestrians, and seismic strengthening, as well as a complete upgrade of the traffic control system and lighting. The deck and trusses were replaced simultaneously while allowing traffic to use the bridge during replacement. Most of the reconstruction occurred during 10-hour shifts at night. Individual deck sections between 10 and 20 meters long were cut away and lowered with a jacking traveler (a gantry-like platform that attached directly to the suspenders of the bridge) to a waiting barge, and the replacement section was lifted into place. When assembled on the bridge, each section was connected to its neighboring section with more than 700 high-strength steel bolts. The first of 54 sections was replaced the weekend of September 9 and 10, 2000, and the final one was replaced the weekend of September 29 and 30, 2001. |
