Abstract
This report summarizes the results of a study into the economic impacts of the transportation damage caused by the January 17, 1994 Northridge Earthquake. The Northridge Earthquake damaged four major freeways in the Los Angeles metropolitan area. Even though state and local agencies responded quickly to reroute traffic and rebuild collapsed bridges and overpasses, major interstates were closed for several weeks and, in some cases, months. This research focuses on the effects of those transportation disruptions on business activity.
