Restoration work on the collapsed Interstate 5 bridge over the Skagit River in Washington state will include the use of "fast-track construction methods" for both temporary and permanent repairs. The temporary fix will involve a pre-constructed steel-girder bridge that would be delivered to the site for faster installation. Later, a permanent span will be built adjacent to the collapsed bridge and slid into place before the temporary bridge is removed. Design for the permanent span is yet to be finalized.
