Agencies with online road and bridge logs are listed below with links to the appropriate sites.

Each county has a different format for their data, so don’t expect bridge and pavement dates for all of them. Some of these county agencies also have publicly available bridge and highway logs. Most agencies do respond quickly to these problems and doing so can help create safer roadways for us all. I highly recommend contacting the agency closest to you should you have any problems with potholes, signs, or other issues. Within these websites, you can find all sorts of valuable data, such as construction projects, closures, detours, and maintenance requests. These agencies maintain most of the roadways outside of incorporated cities, though some cities contract with the county for maintenance. County Highway DepartmentsĬounty Highways are maintained by a separate agency in each county. They can be found on the Structures Maintenance site by clicking here. These are great resources for determining highway construction dates, old alignments, and much more. To report problems on the State Highways, such as I-5, US 101, and SR-71, please use the links below.Ĭaltrans also maintains a database of all their highways and bridges. Caltrans Quickmap is also available in the Apple App Store and Google Play. Traffic cameras, changeable message signs, CHP incidents, and more can be accessed via the site. I highly recommend their “Quickmap” for traffic conditions throughout the state.
