A project where the shape or width of the roadway changes will require more than one of what section?

In project design, especially when dealing with roadways where the shape or width varies, it is essential to utilize multiple typical sections. A typical section illustrates the standard cross-section of the roadway, including elements such as lane widths, shoulder widths, medians, and ditches. When changes occur in roadway shape or width across the project, more than one typical section is required to accurately represent these variations.

Using multiple typical sections allows engineers and planners to clearly communicate how the roadway will be constructed at different segments, ensuring that all stakeholders have the right information for the correct implementation. This clarity is crucial for maintaining compliance with design standards and ensuring the safety and functionality of the road. Having a single typical section would not be sufficient as it would not be able to convey the necessary information for different roadway configurations present in a project with varying geometries.
