The paper shows how the geometric design standards were developed for the 98 kilometre Trans Canada Highway project in New Brunswick. A brief description of the Trans Canada Highway Project (TCHP) and how it fits into the overall transportation system in the province is provided. The paper describes how each geometric design feature was evaluated based on the owner's engineer having a thorough knowledge of the project to be constructed and the adjacent network in which the project was to be incorporated. It also talks about the lessons learned from the project in relation to the establishment of geometric design standards. The paper also talks about the application of an enhanced clear zone concept and how it was used on the project. This concept allowed for low cost safety improvements to be undertaken outside the traditional clear zone limits in order to add value to the project.
