In order to have an accurate 2023 inventory for the NBI submittal replaced or removed structures are not archived from now until the submittal is complete.
These structures will be removed from the SIIMS inventory shortly after a valid tape is submitted.
Although notifications regarding the replaced or removed structures cannot be eliminated, these are
not a concern during this time frame and will be properly handled by Iowa DOT
personnel.
If you are having issues with your LOGIN TO SIIMS, there was a recent change to new usernames and a different authentication process.
