basis every evening from sunset until midnight. Critics derided the effort as a waste of electricity, given Halifax Harbour's frequent foggy weather conditions. The lighting was estimated by the bridge authority to cost in excess of $50,000 a year in 1999. Safety barriers The Angus L. Macdonald Bridge has attracted media attention as the spot where well known environmental activist Tooker Gomberg is believed to have committed suicide on March 3, 2004. In June 2004 the Department of National Defence filed a lawsuit against the Bridge Commission alleging that snow, ice, bottles and other debris rained down on HMC Dockyard below, endangering staff. The DND first sought $527,000 in damages for its efforts to protect employees, an amount that was later increased to $1.04 million. The lawsuit claimed that the issue had been exacerbated when chain link fencing on the bridge had been removed during the 1999 modernization. In July 2007, as part of the settlement, barriers were installed along 22% of the pedestrian lane at the bridge's western end (Halifax abutment) to prevent suicide attempts and protect navy staff below. Initially, the Halifax-Dartmouth Bridge Commission was concerned that the structure was not capable of handling the additional weight of installing safety barriers along the entire span of the bridge. Subsequent computer modeling eliminated the previous concerns, and on May 13, 2009 the general manager and CEO of the Halifax-Dartmouth Bridge Commission, Steve Snider, announced that a tender for the long-called for extension of the barriers along the full length of the bridge would be issued in June 2009. By March 2010, the remaining sections of the safety barrier had been installed. The bridge now has safety barriers installed along 100% of its pedestrian walkways. 2015 "Big Lift" project Beginning in 2015 another major renovation of the bridge started which saw the temporary removal of the pedway and bike lanes. At a cost of $150 million, every piece of steel that makes up the suspended spans, except the towers and two main cables, were replaced; the non-suspended approach spans remained. New vertical cables were required due to the relocation of the stiffening trusses from above deck level to below deck level. Construction mostly occurred overnight with the bridge open to traffic during the day, but many full-weekend closures were necessary. The replacement portion of the project was completed in February 2017. After the Lion's Gate Bridge, this was only the
