All our drawings and details are maintained on the ODOT FTP server, which is open to the general public with no restrictions. If you are unable to open a particular
PDF or DGN on this page, please contact our web editor
who will correct the broken link. However . . .
If you are unable to open any
of the PDF or DGN files on this page, you must contact your IS staff to correct your network problem. While some computer configuration or security settings could block FTP access, this condition is most likely
related to your company's firewall settings. The leading suspect would be some rule or restriction on certain firewall ports. In order to view PDF/DGN files from FTP servers, your firewall must be able to process and allow traffic over port 443. If this port is blocked or restricted, you will not be able to access any of our files. Please contact your IS staff for support.
