Where are bridgemarks measured from in the East Waterway P-18?

Bridgemarks, which are reference points used in construction and engineering projects, are typically established from a specific point to ensure consistent measurement and navigation. In the context of the East Waterway P-18, the bridgemarks are measured from the north end. This is the standard practice in many engineering applications, where a designated starting point along the structure or project is necessary for clarity and accuracy in planning, scheduling, and construction operations.

Understanding that the bridgemarks are defined from the north end provides crucial information for project stakeholders, as it helps in identifying distances, planning work sequences, and setting up project timelines effectively. This north-end reference can serve as the baseline for further measurements required throughout the project, ensuring that all work aligns with the established design and criteria.
