The construction traffic management team analyzed impacts of highway and local road projects in 2014 and identified three hot spots and one watch list area in the greater Puget Sound region. Hot spots are areas where several roadway construction projects occur in close proximity at the same time. Watch list areas also have several projects occurring, but do not necessitate the extra coordination required by a hot spot. We track watch lists because they may require additional coordination as updated closure information becomes available. Early coordination in hot spots keeps traffic moving during construction and helps projects stay on time and within budget.

How to Read Maps and Schedules
Project data for each area is represented in two documents: maps and schedules. Each of these documents displays the project data in different ways.
Maps are visual tools used to show approximate project locations and anticipated impacts. The maps represent all projects occuring during the time period listed in the heading; not all projects shown on the map will occur at the same time. If the map heading says '1/1/2014-1/31/2014', this means that all project on the map occur in January 2014. The numbers used to label projects on the maps correspond to the ID number in the schedule.
Schedules provide more detailed information about the anticipated impacts for each project. Basic project information (ID number, project title, start and end date, contact information, etc) is displayed on the left and detailed impact information is shown on the right.
Instructions for reading and interpreting maps and schedules are shown in the introduction to hot spot maps and Gantt charts (pdf 29 kb) .

Watch List Information*
SeaTac (updated: 3/31/2014)
This area is on our watch list due to the number of projects affecting routes parallel to I-5, such as SR 167 and Military Road. At this point there aren't any major conflicts, but we continue to watch it in case there are any changes or if any new projects arise.

* Please note:
- Information on the maps and schedules is useful for planning purposes, but is subject to change without notice due to the fluid nature of construction schedules. Closure information tends to become more accurate as the closure date approaches. For more information about construction closures occurring in the next week, check out our Construction Update page.
- Maps and schedules focus on highway and arterial construction and do not list every construction project in every neighborhood
- Maps and schedules include information from multiple public agencies for coordination and planning purposes; each agency retains responsibility for their own construction and related traffic closures.
- For more detailed information about construction in Seattle, check out the Seattle Department of Transportation's construction closures page.
- Maps and schedules are numbered as a single set for each area, but are divided into separate pdfs for ease of use.
- Maps are designed for printing on 11'' by 17'' paper.
- Schedules are designed for printing landscape on 11" by 17" paper.
