Construction Projects

Traffic will be maintained in most areas during construction, however, delays should be expected. Some projects will require road closures and detours. Visit the Road Closures page for a list of current and upcoming planned closures and detours.

You can find a list and maps of approved, scheduled road and bridge projects for the 2026 construction season in the 2026-2030 Roads Construction Program, along with a list of future planned projects.
