Description

The Roadside Design Guide states that the minimum bridge width for new bridge construction is 9.0m. However, the closest configurations of SLC girders to this standard provide either 8.7m or 9.9m clear roadway. Technically, the minimum standard would rule out use of the 8.7m clear roadway configuration. However, due to the potentially significant cost increase, the practice outlined in this resource has been developed to achieve a balance between the principles behind the minimum standard and the available structure options.
