Caltrans QuickMap vs FloodRoute

Know Before You Go: QuickMap puts real-time California traffic data straight from Caltrans in the palm of your hand — so you can plan smarter, avoid delays, and drive with confidence. What's on the map: - Freeway speeds and congestion - Live traffic cameras and snapshots - Lane closures and CHP incidents - Chain controls and snow plows - Changeable message signs - Border wait times - Safety roadside rest areas, Park & Ride lots - Commercial vehicle information including: -- Weigh stations and Escape Ramps -- Terminal/Service Access Ramps -- Overweight Corridors and California Truck Networks Auto-refresh will refresh data every 3 minutes unless a different refresh interval is selected in the settings screen. Manual refresh is also available via the refresh button at the bottom right of the map. Enable Geotargeted Notifications to receive alerts about road closures near you — even when the app is closed. Note: If you choose to enable Geotargeted Notifications, this app will monitor your location in the background and alert you (via a Push Notification) to State Highway System road closures occurring near you. Continued use of background location may decrease battery life. Questions or something not looking right on the map? We want to hear from you — reach us at quickmap@dot.ca.gov.

AS FEATURED IN THE ARK NEWS (Jan 28, 2026) in Tiburon, CA, FloodRoute shows which roads may flood during high tides, before you drive into trouble. Using NOAA tide data, OpenWeatherMap barometric pressure, Open-Meteo rainfall data, road elevation mapping, FEMA flood zone data, historical news records, and crowdsourced user-submitted verifications, FloodRoute provides realtime estimations of flood-prone streets -- and "what if" scenarios -- so you can plan safer routes in coastal communities. AVAILABLE IN 6 REGIONS: • Boston, MA • Marin County, CA • Miami, FL • New York City, NY • San Francisco, CA • Tampa, FL My first iOS app, FloodRoute was inspired by Nextdoor neighbors in my home of Marin County.
