It also offers a direct tram link for the almost 400,000 bus passengers a week who use services at the Moor Street bus interchange.
Mayor Richard Parker has earmarked £400m to build the tram extension to the new stadium and surrounding Sports Quarter regeneration scheme.
The money is also being used to plan and design the full East Birmingham and Solihull extension out to Birmingham Airport and HS2 Interchange.
Late night tram runs will continue over the next few weeks as Midland Metro Alliance engineers fully test the line and fine tune the track ready for the route to be handed over to West Midlands Metro for driver training and timetable testing.
Passenger services will start in the autumn following the completion of the testing.
The tests are the first time trams have run down Lower Bull Street, Albert Street and across Moor Street Queensway, before stopping at a temporary terminus next to the Eastside City Park.
