Cardiff Council say that building a tram linking Cardiff Bay and the city centre "remains a priority." In the green paper published today, the council say that Light Rail Transit system would "encourage development and enable the expansion of the city centre southwards."
If built, it would follow a similar route to the current rail link to Cardiff Bay.
The paper also says that completing the Cardiff Bay link road to the east of the capital "remains a priority" to avoid people driving through the city.
A new Indoor Arena is also included in the plans along with new public open spaces.
It also suggests 6,000 new homes between Cardiff Bay and the city centre.
