Alterations

The original stringer-supported bridge was constructed in 1951. It was designed to comply with the HS20 design codes released by the American Association of State Highway and Transportation Officials, which were current at the time.

In the early 1990s, the government of British Columbia, responsible for the upkeep of Rock Creek Canyon Bridge, reviewed it and decided that the structure was not wide enough to cope with modern traffic. Instead of replacing the bridge altogether, significant alterations to the bridge were made in 1992, a much less expensive option. The capacity of the structure was increased to comply with more rigorous and up-to-date design codes. The deck was widened, from 7.3 metres (24 ft) to 10 metres (32.8 ft), and was made of composite steel and concrete. Additionally, some seismic improvements were undertaken and the bridge was repainted. These works were designed and supervised by Buckland and Taylor Ltd, a bridge engineering firm, and the project was delivered on time and under budget. The construction works were phased, keeping one lane open at all times to minimise the traffic disruption that a full closure would cause.
