Focal Point Markers are signs placed on the left side of the road and read in the direction of travel. Focal Point Markers provides road users with a distance to larger town centres, roadhouses or well known features along roads in remote localities.This layer indicates the location of Focal Point Markers on the State Road Network and is provided for information only.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

SLKs or Straight Line Kilometers are a location reference system used by Main Roads Western Australia to define the location of features or events along a road. This layer shows SLK points (every 100m) along the left and single carriageways for all State and Local Roads, Main Roads controlled paths contained within the road centreline of Main Roads road asset database. The purpose of this layer is to identify and label the measure of SLK along a particular route and is provided for information only. The SLK points are based on geometric measure and include points of equation. This means that you may notice “jumps” in the SLK between two points that are not equal to 100m. This is as a result of network changes that have been incorporated into the spatial road centr eline.A point of equation is a business term used to describe a point on the road network, which has two SLK references, one for the section leading up to it, and one for the section leaving from it. A Point of Equation is either: •A gap, which occurs when the new deviation/realignment is built shorter than the existing road. An SLK range is missing. •An overlap, which occurs when the new deviation/realignment is built longer than the existing road. An SLK range is duplicatedNote that you are accessing this data pursuant to a Creative Commons (Attribution) Licence, which has a disclaimer of warranties and limitation of liability.

This layer shows the location of regulatory signs & Main Roads Western Australia is the responsible authority. The term regulatory sign describes a range of signs that are used to indicate or reinforce traffic laws, regulations or requirements which apply either at all times or at specified times or places upon a street or highway, the disregard of which may constitute a violation. One type of regulatory signs are stop signs or give way signs, intended to instruct road users on what they must or should do (or not do) under a given set of circumstances. Signs can be on the State Road Network or other public access roads and is provided for information only.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

Layer of Structures (road and pedestrian bridges, rail bridges, sign gantries and tunnels), in Western Australia. This layer provides general inventory information for all Structures on State roads, Local roads or Department of Environment and Conservation (DEC) roads. A road structure is that portion of the carriageway that carries vehicular, pedestrian, and bicycle traffic over or under an obstruction such as a watercourse, another road or railway line.

Speed Zones (State and Local Roads)This layer shows the location of Speed Zones on all public access roads found in the Integrated Road Information System (IRIS) and includes temporal speed zones such as school zones. A school zone refers to an area on a street near a school or near a pedestrian crossing leading to a school that has a likely presence of younger pedestrians. School zones generally have a reduced speed limit during certain hours.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

Please use as a reference only and verification is to be undertaken on site.2. Confidence Rating has been assigned to individual assets to provide an indication of the accuracy of the data. However please note that this is only an estimated rating which should be used as a reference only.3. Asset Owner – Please note that Main Roads WA drainage data includes multiple organisations’ interface drainage and, as a result, the ‘Asset Owner’ attribute is only to be used as a reference only as it may be inaccurate and should not be referred to as the source of truth.4. Asset Types:a. Interfacing Structuresi. Note that the drainage data includes interface points between Main Roads WA drainage structures and structures owned by other asset owners. However not all assets owned by other asset owners have been included. Please seek clarification from the respective asset owners if required.b. Ghost Linki. Ghost link can be used to represent an interfacing drainage network not owned by Main Roads WA. These are commonly used to simplify complex networks located downstream on route to the ultimate stormwater outlet destination.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.
