Tools

12 tools split across two domains — traffic (WSDOT Traveler API) and ferries (WSF Ferry API):

wsdot_get_mountain_passes

Current road conditions for all WA mountain passes.

• Covers all 16 passes: Snoqualmie, Stevens, White, Blewett, Cayuse, and others
• Fields include status (Open/Closed/Caution), road surface, active traction law, temperature, and elevation
• Use for "is the pass open?", traction law checks, or winter driving planning

wsdot_search_alerts

Active WA highway alerts — incidents, construction, closures, restrictions.

• Filter by state route — natural forms all work: "I-90", "90", "090", or "SR 520" / "520"
• Filter by WSDOT region: Northwest, Olympic, Southwest, South Central, North Central, Eastern
• Filter by milepost range to scope to a corridor — an alert matches when its extent overlaps the range, so a closure that spans the boundary is returned
• Omit all filters to return all current statewide alerts
• Descriptions are plain text — upstream authors them with markup, and a link is rendered inline as link text (url) so the destination survives
• Results are ordered by alertId and paged (default 50, max 500) — pass offset/limit to page through the full statewide set; the notice reports the next offset. Upstream returns the same alert set in more than one row order, so the ordering is imposed here to keep a given offset reproducible

wsdot_get_travel_times

Current vs. average travel times for named WA highway corridors.

• Covers I-5, I-90, SR 520, SR 99, I-405, SR 167, and others
• Filter by route ("I-5", "5", "SR 520") to get every corridor measured on it, or by any text to match corridor names ("Everett")
• When current time exceeds average, the corridor is congested; the delta is the delay
• Reversible express-lane corridors report no travel time while closed in the queried direction — those figures are omitted rather than reported as zero minutes
• Results are paged (default 50, max 500) — pass offset/limit to page through the full statewide set; the notice reports the next offset

wsdot_get_toll_rates

Current dynamic toll rates for WA tolled facilities.

• SR 99 (WSDOT Tunnel), SR 167 HOT Lanes, I-405 Express Lanes, the SR 509 tolled segment, and the SR 520 Bridge
• Rates are time-banded and change dynamically based on traffic conditions
• stateRoute is a bare, zero-padded route number ("099", "405") with no route type; the rendered text resolves the posted designation, so I-405 reads as I-405 rather than SR 405
• Each entry leads with its readable startLocationName → endLocationName segment; the opaque upstream trip key stays available as tripName
• Results are paged (default 50, max 500) — pass offset/limit to page through the full statewide set; the notice reports the next offset

wsdot_get_border_waits

Current vehicle wait times at WA/Canada land border crossings.

• Covers I-5 (Peace Arch, Blaine), SR 543 (Pacific Highway, Blaine), SR 539 (Lynden), and SR 9 (Sumas)
• Each crossing reports a general-purpose lane and a Nexus lane; SR 539 adds a truck lane and SR 543 adds truck and FAST truck lanes — eleven entries in crossings[], one per lane
• crossingName is a route code (e.g. I5, SR543Trucks); location.description holds the readable name
• Wait times in minutes; updateTime is ISO 8601. A crossing reporting no current data is still returned — only waitTimeInMinutes is omitted, and the rendered text reads Not available

wsdot_search_cameras

WSDOT highway camera metadata and image URLs.

• Filter by state route ("I-90", "90", "SR 520", or "520" all work), WSDOT region, or milepost range
• Camera road names carry a route-type prefix, so "SR 26" excludes US 26 and "US 97" excludes US 97A; a bare "26" returns both
• Returns metadata and image URLs — camera images are copyright WSDOT, not fetched as bytes
• Results are ordered by cameraId and paged (default 50, max 500) — pass offset/limit to page through the full statewide set; the notice reports the next offset. Upstream returns the same camera set in more than one row order, so the ordering is imposed here to keep a given offset reproducible

wsdot_get_ferry_terminals

All WSF ferry terminals with numeric IDs.

• 20 terminals; the list rarely changes
• Call this first to resolve human-readable names (e.g. "Bainbridge Island", "Seattle", "Kingston") to the numeric IDs required by wsdot_get_ferry_schedule and wsdot_get_terminal_space

wsdot_get_ferry_routes

WSF ferry routes operating on a given date.

• Returns each route's ID, abbreviation, and description
• Route IDs correspond to impactedRouteIds in wsdot_get_ferry_alerts — use this tool to resolve alert route IDs to route names
• Use to discover which routes are running; for the numeric terminal IDs that schedule and space lookups need, call wsdot_get_ferry_terminals

wsdot_get_ferry_schedule

Departure times for a specific WSF ferry route.

• Requires numeric terminal IDs — use wsdot_get_ferry_terminals first
• remainingOnly: true returns only future departures for today (useful for "next ferry" queries)
• For future dates, all sailings for that day are returned
• departureTime and arrivalTime are ISO 8601 UTC, while tripDate is the Pacific service day — an evening sailing therefore carries the following UTC calendar date and will not match tripDate. Convert to America/Los_Angeles before quoting a clock time
• arrivalTime is populated on some routes and absent on others
• No cancellation status — WSF drops a cancelled sailing from the schedule rather than flagging it, so a listed sailing is not confirmation it will run; check wsdot_get_ferry_alerts, which reports disruptions at route level

wsdot_get_vessel_locations

Real-time AIS positions for all active WSF vessels.
