Transit System Impacts
(formerly Construction Information Center)
The Metro Transit System Impacts Group serves as the first point-of-contact at Metro Transit for public or private contractors, including city, state or other government agencies planning construction projects that may impact Metro transit or the Seattle Streetcar service or properties.
The Metro Transit System Impacts Office requires construction notification and offers these guidelines for construction activities that have the potential for impacting Metro transit or the Seattle Streetcar Operations including Trolley or streetcar overhead outage requests, Special Events that would impact Transit, or any event impacting transit routes, bus stops, facilities, or properties.
We require you to email us prior to your event for information about how your project may impact Transit Operations. This allows us to best advise you on your submittal for street use permits and/or special event permits and our requirements. Please refer to Downloads & resources for detailed information.
