months, and cost about $3m. In the mid-1990s, the bridge underwent seismic upgrades, which comprised deficient bearings, piers and foundations, and potential soil liquefaction. The work included 800 stone columns installed along either side of the bridge for ground improvement. Richmond, about metre above sea level, requires drainage and flood protection. To this end, Grauer Road was raised to 4.7m, which would handle a one-metre rise in sea level. At the road perimeter, the installation of a buried steel sheet pile wall will ensure the bridge piers remain flexible in a seismic event. The road base comprises pumice for light weight and drainage. The project was completed in 2014 for the opening of the McArthurGlen outlet mall. In 2008, Translink added a bus lane on Russ Baker Way, between Gilbert Road and Cessna Drive. To respond to 127 crashes each year on the bridge, camera monitoring was added and a tow truck stationed at the south end of the bridge during morning rush hour. In 2014, the adjustment of vehicle lane widths allowed bike-lane widening to improve safety for cyclists. Gliding above In May 1981, a Cessna 172, that ran out of fuel, crash landed on the bridge deck, but caused no injuries. Since completion of the north runway in 1996, primarily used for landings, signs have warned bridge traffic of low flying aircraft. The Middle Arm SkyTrain Bridge, which opened in 2009, passes over the Arthur Laing southern approach.
