There is now an official CBS website for THE BRIDGE.
http://www.cbs.com/primetime/the_bridge
At the moment the website only has a show synopsis and a cast list. So check back for updates.
UPDATE: When you click on SHOWS in the header on the CBS website it lists THE BRIDGE with an * after it.
The * (highlighted in yellow in the below screen cap) reads * Denotes NEW Fall show.
‘New Fall show’ not a ‘mideseason show’?!?!? Fingers crossed this isn’t just a typo.
