The Molonglo Valley has two arterial road corridors, one running east to west and the other north to south. The North South Arterial has been named John Gorton Drive. The East West Arterial (EWA) has yet to be named and expected to be completed before 2041. The East West Arterial includes a bridge over the Molonglo River and a new East West Arterial / Tuggeranong Parkway Interchange. The route is decided and traffic studies are underway.
