What solution is recommended to meet the minimum clearance to a historic tower if design review shows it is not met?

The recommendation to increase the tangent distance is rooted in providing the necessary horizontal clearance to a historic tower without altering its position or immediate surroundings significantly. By increasing the tangent distance, the road alignment can be adjusted to ensure that the minimum clearance is achieved, while also maintaining safety and minimizing impacts on the historic structure.

This approach respects the integrity of the historic tower since it avoids potentially disruptive changes, like shifting the tower itself or changing its immediate environment. It provides a sustainable solution that prioritizes both the preservation of historical features and adherence to design standards.

Adjusting the tangent distance can facilitate smoother transitions in road geometry, accommodating vehicles while ensuring long-term safeguarding of the structure. This method is often preferred when working around sensitive sites because it strikes a balance between necessary infrastructure modifications and the protection of cultural or historical assets.
