A Guardrail is a barrier fastened to the end of a bridge abutment, along the shoulder of a road or between travel lanes of opposing traffic. It is a Linear feature

The Road Structures on the highway that are maintained by the Ministry. Highway structures include bridges, culverts (greater than or equal to 3m diameter), retaining walls (perpendicular height greater than or equal to 2m), sign bridges, tunnels/snowsheds. Information is recorded in the Bridge Management Information System (BMIS)

A Retaining Wall is a structure designed to protect the road infrastructure by retaining materials on the fill side to prevent road bed slips and by retaining materials on the cut side to prevent the road surface from being covered by debris. Retaining walls that are greater than or equal to 2m in height are stored in the MoT Bridge Structure Road dataset. It is a Linear feature

This layer contains point representation of bridge, tunnel and ferry events along the Alberta road network.

All bridges in Ontario are inspected every 2 years using the Ontario Structure Inspection Manual (OSIM) format. The weighted condition of all elements is summarized in the Bridge Condition Index (BCI). More details about the BCI can be found on [the Bridge Safety page](http://www.mto.gov.on.ca/english/highway-bridges/ontario-bridges.shtml) on the Ministry of Transportation website. Bridges that were recently constructed or recently transferred to the Ministry of Transportation may not have been inspected in OSIM format yet. *[OSIM]: Ontario Structure Inspection Manual *[BCI]: Bridge Condition Index

A Culvert is a pipe (less than 3m in diameter) or half-round flume used to transport or drain water under or away from the road and/or right of way. Culverts that are greater than or equal to 3m in diameter are stored in the MoT Bridge Structure Road Dataset. It is a Point feature

BRIDGES_PT_25K contains center point locations of bridges along roads. It does not include bridges along Unmaintained Roads.Distributed from GeoYukon by the Government of Yukon.

All available bathymetry and related information for Bridge Lakes were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.
