Bridge Points Cape Cod 2025

Overview This Feature Service provides detailed spatial data representing bridges across Cape Cod, Massachusetts. Collected and updated using high-resolution aerial imagery captured in the spring of 2025, the dataset supports accurate and current planimetric mapping with a horizontal positional accuracy within 0.38 meters. Feature Layer BridgePoint : This layer captures detailed information on bridge structures that facilitate the crossing of obstacles such as rivers, canals, railways, or roads. It includes data on bridge identifiers, names, types, designs, traffic usage, and structural characteristics such as span type, deck type, and measurements like span length and deck thickness. Condition and ownership attributes are also recorded to support asset management and maintenance planning. The data were sourced from aerial photography taken under optimal acquisition conditions ensuring minimal shadows and clear views for precise mapping. Geographic Coverage The dataset covers the Cape Cod region in Massachusetts, encompassing multiple towns such as Barnstable, Bourne, Falmouth, and others, providing comprehensive bridge asset data essential for regional planning and infrastructure management. Data Quality and Currency The imagery used has a ground sample distance of 7.5 cm enabling detailed planimetric feature extraction suitable for large-scale mapping and analysis. The data's recency from 2025 ensures up-to-date infrastructure information for decision-making and resource allocation.
