To edit or update a Worksite or Traffic Management Plan (TMP) that has been submitted, approved, or declined, you must first create a revision of the application.

To revise a worksite, you can click on the 'Create revision' button in the footer of the declined Worksite.

To revise a TMP and make changes to it, you can click on the 'Create revision' link on the TMP, under the TMPs section in the Worksite application.
